**64200    (Wingine) High Performance 'Windows Engine'         c:Oct91...
***Info:...
****General:
The  concept  behind  the  64200  'Windows Engine'  (Wingine)  is  the
implementation of video display memory  as a bank (or banks) of system
memory.  The  idea  is that  the  system  CPU  (typically at  least  a
386-class processor)  can manipulate pixels  on the screen  quickly if
the  display  memory  bottleneck  is  removed.  The  video  memory  is
accessed directly by the system CPU as a frame buffer through the VRAM
random access  port while the display is  continuously being refreshed
via the VRAM serial data port.

Wingine  is  basically a  standard  16-bit  VGA  with extensions.  The
primary  extension is  to allow  the  system to  directly access  VRAM
display  memory as  system  memory.  Wingine  operates  in two  modes:
'Windows Acceleration'  mode and 'VGA'  mode.  In 'VGA'  mode, Wingine
drives the video memory.  Wingine uses  the VRAMs as DRAMs in VGA mode
(no special capabilities  of the VRAMs are required  or used); all VGA
operations are  implemented via the VRAM random  access port. (Wingine
pinouts are  defined such that future implementations  may be extended
to take advantage  of the VRAM serial port in  VGA mode.)  In 'Windows
Acceleration' mode,  the VRAM  random access ports  are driven  by the
system memory controller; the Wingine chip does not have access to the
VRAMs, but performs all VRAM serial data shift operations and provides
HSYNC and  VSYNC for the  display monitor.  In  'Windows Acceleration'
mode,  the  system performs  all  data  transfer  operations based  on
information provided from the Wingine chip.

The  result is  very high  performance, since  the entire  random port
bandwidth  is available for  CPU access  and the  VRAMs may  always be
accessed at full memory speed.  In addition, memory may be accessed at
the full width of system memory (16 or 32 bits).  The frame buffer may
be accessed  as a linear array  of pixels (in  'packed- pixel' format)
anywhere in the system memory space.

Another major  advantage is  the ability to  accept 32 bits  of serial
data from  the VRAMs and  convert it into  an 8-bit video  data stream
compatible  with  a standard  low-cost  VGA  RAMDAC.  This  capability
removes   the   requirement   for   an  expensive   RAMDAC,   allowing
implementation of cost effective, high performance graphics system.

Wingine  directly supports 4bpp  (nibble) and  8bpp (byte)  modes with
standard VGA  8-bit RAMDACs  which are available  up to 80  MHz. 16bpp
mode may  be supported  with an extended  capability RAMDAC such  as a
Sierra SC11482, 483, or 484. Wingine can also support various types of
high performance and extended  capability RAMDACs with 32-bit parallel
data input ports.  These RAMDACs  typically support pixel rates to 135
MHz and  modes of 1bpp, 2bpp, 4bpp,  8bpp, 16bpp, and /  or 24bpp. All
known RAMDACs support these modes  lsb first (e.g., nibble modes shift
the  first pixel out  of bits  0-3 of  the first  byte in  memory, the
second pixel  out of bits 4-7, etc).   All of these modes  up to 16bpp
are also  supported in the XGA  ('lsb first' is referred  to as 'Intel
order'  in IBM's  XGA documentation).   Therefore,  for compatibility,
pixel shift order is always lsb  first and pixels are always stored in
Wingine memory  as a  linear array of  n-sized elements  starting with
bit-0 of byte 0.

DISPLAY MEMORY CONFIGURATIONS
The  VRAM frame buffer  may be  implemented with  two, four,  or eight
256Kx4 (1Mb) or two or four  256Kx8 (2Mb) VRAMs, accessed as 1 bank of
32-bit memory in 386 DX or 486  systems or as 2 banks of 16-bit memory
in  386 SX systems.   This provides  1MB of  display memory,  which is
adequate for support  of 1024x768 at 8bpp (256-color).  This amount of
memory, using split buffer VRAMs  and a Sierra RAMDAC (or equivalent),
will also support 16bpp modes up to 800x600.

Wingine allows  512KB upgradable  to 1MB of  display memory in  386 SX
(16-bit) systems  by optionally populating the upper  bank.  The 512KB
configuration supports 1024x768 at 4bpp (16-color) and 640x480 at 8bpp
(256-color).   If word  interleaving is  done in  16-bit  systems, the
memory map  is identical between 16  and 32 bit systems  (and the same
drivers   may  be  used).    Wingine  is   designed  to   also  handle
non-word-interleaved 2  bank 16-bit memory maps,  if word interleaving
is not implemented by the system.

If 256Kx4 VRAMs are used,  512KB of display memory (upgradable to 1MB)
may also be  implemented by optionally populating the  upper nibble of
each byte.  In this  configuration, the system would always manipulate
display memory assuming 8bpp; screen  display would be 16-color with 4
VRAMs installed and 256-color with 8 VRAMs installed (the RAMDAC pixel
mask register would be set to mask  out the upper 4 bits of video data
in 4-VRAM mode).

Wingine will support 24bpp modes  up to 640x480 in 1MB configurations,
but a RAMDAC must be used which allows packing R, G, & B every 3 bytes
and  AT&T  206491 RAMDACs.   The  Bt482  support  this type  of  pixel
packing. However Wingine will support 24bpp modes up to 640x400 if the
RAMDAC ignores one byte out  of every four.  Many 32-bit input RAMDACs
(Bt484 / 485, TI 34075 / 34076) support 24bpp mode in this fashion (by
ignoring the upper byte of the 32-bit input).  Since only one pixel is
input to the RAMDAC every shift  clock, the maximum pixel rate in this
mode is limited by the VRAM shift clock rate: 33 MHz for '-10' (100ns)
VRAMs and 40 MHz for '-8' (80ns) VRAMs).

Wingine supports interlaced  displays at 1024x768 resolution.  Wingine
maintains a linear address mapping scheme so that software drivers are
independent of whether the display is interlaced or not.

Wingine is compatible with VRAM memory configurations larger than 1MB,
if implemented by the system as either multiple banks of 32-bit memory
using '256K x N' VRAMs or  single banks of 32-bit memory using '512K x
N'  or  '1M x  N'  VRAMs.   These  configurations would  typically  be
implemented  with  32-bit  input  extended-function,  high-performance
RAMDACs  and   support  high  resolutions   (e.g.,  1280x1024)  and/or
high-color modes (16bpp and 24bpp).

SYSTEM SUPPORT REQUIREMENTS
To implement  a Wingine-based  Graphics sub-system, the  system memory
controller must  be able to  map a bank  (or banks) of VRAMs  into the
system  memory space.   The memory  controller  must be  aware of  the
differences  between VRAMs and  DRAMs for  random access  port control
(the  VRAM serial  port is  controlled by  Wingine).   Wingine support
exists in  the CS4021  486 CHIPSet.  Chips  and Technologies  plans to
provide  Wingine support  in  all future  Systems  Logic CHIPSets  and
SYSTEMSets to  allow Wingine to interface directly  to those products.
Extensions are also planned for all current CHIPSets and SYSTEMSets.


MEMORY INTERFACE
Two types of  memory subsystems can be designed  with Wingine.  In the
first type,  2 or 4 DRAMs can  be used for VGA  compatible modes.  For
Wingine modes,  separate VRAMs are used.  In  this implementation, VGA
memory and  'Wingine mode' memory  are separate.  No  external buffers
are required to isolate the two memory buses.

In the  second type of memory  subsystem, a shared memory  bus is used
for a  cost effective  implementation.  In this  case, only  VRAMs are
used. In VGA  mode, Wingine controls video memory.  In 'Wingine' mode,
the system memory controller  has control over video memory.  External
buffers are required to isolate the two buses - the Wingine memory bus
and  the  system memory  bus.   Refer  to  the following  section  for
additional details.

Wingine can  support up to  2 Mbytes of  display memory.  It  can also
support 256 Kbyte and  512 Kbyte memory configurations.  The following
table  shows a  matrix of  resolution and  memory  requirements.  This
table  assumes  a shared  memory  architecture.   It  is important  to
buffers SCLK with a fast buffer when 2 Mbyte configuration is used.

SYSTEM INTERFACE
The  64200 Wingine  chip is  tightly coupled  to system  chipsets from
Chips and  Technologies.  This tight coupling between  Wingine and the
system   chipset  results   in   a  very   high  performance   Windows
architecture.  The  Wingine graphics  controller can be  interfaced to
two high performance  CHIPSets from Chips & Technologies  - the CS4021
and CS82310 chipsets.

***Notes:...
***Info:
The 82395DX High  Performance 82395DX Smart Cache is  a low cost, high
integration, 32-Bit peripheral for  Intel's i386 DX Microprocessor. It
stores a copy of frequently accessed  code or data from main memory to
on chip data RAM that can be accessed in zero wait states. The 82395DX
enables the 386 DX Microprocessor to run at near its full potential by
reducing the average  number of wait states seen by  the CPU to nearly
zero.  The dual  bus architecture allows another bus  master to access
the System Bus while the 386  DX Microprocessor can operate out of the
82395DX's  cache  on  the  Local  Bus.  The  82395DX  has  a  snooping
mechanism which maintains cache coherency during these cycles.

The  8239SDX  is   completely  software  transparent,  protecting  the
integrity  of system software.  High performance,  low cost  and board
space saving  are achieved due to  the high integration  and new write
buffer architecture.

1.0 82395DX FUNCTIONAL OVERVIEW
1.1 Introduction
The  primary function  of  a cache  is  to provide  local storage  for
frequently  accessed memory  locations.  The  cache  intercepts memory
references and handles them  directly without transferring the request
to the System Bus. This results in lower traffic on the System Bus and
decreases  latency   on  the  local  bus.   This   leads  to  improved
performance for a processor on the Local Bus. By providing fast access
to frequently  used code  and data,  the cache is  able to  reduce the
average memory access time of the 386 DX Microprocessor based system.

The 82395DX is a single chip cache subsystem specifically designed for
use  with the  386  DX Microprocessor.   The  82395DX integrates  16KB
cache, the Cache Directory and the Cache Control Logic onto one chip.

The 82395DX is  expandable such that larger cache  sizes are supported
by cascading 82395DXs. In a single 82395DX system, the 82395DX can map
4 Giga  bytes of main memory into  a 16KB cache.  In  the maximum con-
figuration of a  four 82395DX system, the 4 Giga  bytes of main memory
are mapped into  a 64KB cache. The cache is unified  for code and data
and is  transparent to application  software.  The 82395DX  provides a
cache consistency  mechanism which guarantees  that the cache  has the
most recently updated version of the main memory.  Consistency support
has no  performance impact on  the 386 DX Microprocessor.  Section 1.2
covers all the 82395DX features.

The 8239SDX cache architecture is similar to the i486 Microprocessor’s
on-chip cache. The  cache is four Way set  associative with Pseudo LRU
replacement  algorithm.  The  line  size is  16B  and a  full line  is
retrieved from the  memory every cache miss. A  TAG is associated with
every 16B line.

The 82395DX  architecture allows for cache  read hit cycles  to run on
the  Local Bus  even when  the System  Bus is  not  available. 82395DX
incorporates a  new write buffer cache architecture,  which allows the
386 DX Microprocessor to  continue operation without waiting for write
cycles to actually update the main memory.

A  detailed  description of  the  cache  operation  and parameters  is
included in chapter 2.

The 82395DX has an interface  to two electrically isolated busses. The
interface to the 386 DX Microprocessor bus is referred to as the Local
Bus (LB) interface. The interface  to the main memory and other system
devices is referred  to as the 82395DX System  Bus (SB) interface. The
SB interface emulates the 386  DX Microprocessor. The SB interface, as
does the 386 DX Microprocessor, can be pipelined.

in  addition,  it is  enhanced  by an  optional  burst  mode for  Line
Fills.  The  burst  mode   provides  faster  line  fills  by  allowing
consecutive read cycles to  be executed at a rate of up  to one DW per
clock cycle. Several  bus masters (or several 82395DXs)  can share the
same System Bus and the  arbitration is done via the SHOLD/SHLDA/SBREQ
mechanism   (similar   to   the   i486  Microprocessor)   along   with
SFHOLD#. Using  these arbitration mechanisms,  the 82395DX is  able to
support a  multiprocessor system (multi  386 DX Microprocessor/82395DX
systems sharing the same memory).

Cache  consistency   is  maintained  by   the  SAHOLD/SEADS#  snooping
mechanism, similar to the i486  microprocessor. The 82395DX is able to
run a zero  wait state 386 DX Microprocessor  non-pipelined read cycle
it the data exists in the cache. Memory write cycles can run with zero
wait states if the write buffer is not full.

The 82395DX cache  organization provides a higher hit  rate than other
standard  configurations.    The  82395DX,  featuring   the  new  high
performance write buffer cache architecture, provides full concurrency
between  the electrically  isolated Local  Bus and  System  Bus.  This
allows the 82395DX  to service read hit cycles on  the Local Bus while
running  line  fills or  buffered  write  cycles  on the  System  Bus.
Moreover, the  user has the  option to expand  his cache system  up to
64KB.

1.2 Features
1.2.1 82385-LIKE FEATURES
o The 82395DX  maps the  entire physical address  range of the  386 DX
  Microprocessor (4GB) into 16KB, 32KB,  or 64KB cache (with one, two,
  or four 82395DXs respectively).

o Unified code and data cache.

o Cache  attributes are  handled  by hardware.   Thus  the 82395DX  is
  transparent to application software. This preserves the integrity of
  system software and protects the users software investment.

o Double Word, Word and Byte writes, Double Word reads.

o Zero wait states in read hits  and in buffered write cycles. All 386
  DX  Microprocessor  cycles are  non-pipelined.   (Note:  The 386  DX
  Microprocessor must never be pipelined  when used with the 82395DX -
  NA# must  be tied to  Vcc).  

o A hardware cache FLUSH# option.  The 82395DX will invalidate all the
  Tag Valid bits in the Cache  Directory and clear the System Bus line
  butter when  FLUSH# is activated for  a minimum of  four CLK’s.  The
  line buffer is also FLUSH #ed.  

o The 8239SDX supports non-cacheable accesses.  The 82395DX internally
  decodes the 387 DX Math Coprocessor accesses as Local Bus cycles.  

o The system bus interface emulates a 386 DX Microprocessor interface.

o The 82395DX supports pipelined and non-pipelined system interface.

o Provides  cache  consistency (snooping):  The  82395DX monitors  the
  System Bus address  via SEADS# and invalidates the  cache address if
  the System Bus address matches a cached location.

1.2.2 NEW FEATURES

o 16KB on chip cache arranged in four banks, one bank for each way. In
  Read hit  cycles, one DW  is read.  In  a write hit cycle,  any byte
  within the DW  can be written.  In cache fill  cycle, the whole line
  (16B) is written.  This large  line size increases the hit rate over
  smaller line size caches.  

o Cache architecture  similar to  the i486 Microprocessor  cache: Four
  Way SET associative with Pseudo LRU replacement algorithm. Line size
  is 16B  and a  full line  is retrieved from  memory for  every cache
  miss. Tag.  Tag Valid Bit  and Write Protect Bit are associated with
  every Line.  

o New  write  buffer  architecture  with  four DW  deep  write  buffer
  provides zero  wait state memory  write cycles. I/O,  Halt/ Shutdown
  and  LOCK#ed  writes  are  not  buffered.

o Concurrent Line Buffer Cacheing: The  82395DX has a line buffer that
  is used as additional memory.  Before data gets written to the cache
  memory at the completion of a Line Fill it is stored in this buffer.
  Cache hit  cycles to the  line buffer can  occur before the  line is
  written to  the cache.

o Expandable: two  82395DXs support  32KB cache memory,  four 82395DXs
  support 64KB cache memory. This gives the user the option of config-
  uring a system to meet their own performance requirements.  

o In 387 DX Math Coprocessor  accesses, the 82895DX drives the READYO#
  in one  wait state  if the  READYI# was not  driven in  the previous
  clock.
  Note that  the timing of the  82395’5 READYO# generation  for 387 DX
  Math Coprocessor cycles is incompatible with 80287 timing.

o The  82395DX   optionally  decodes  CPU  accesses   to  Weitek  3167
  Floating-Point  Coprocessor address  space  (COOOOOOOH-ClFFFFFFH) as
  Local Bus  cycles. This option  is enabled or disabled  according to
  the LBA# pin value at the falling edge of RESET.

o An enhanced  System Bus interface:  
  a) Burst option  is supported  in  line-fills  similar  to the  i486
     Microprocessor.   SBRDY#  (System  Burst  READY) is  provided  in
     addition to SRDY#. A burst is always a 16 byte cache update which
     is equivalent  to four DW cycles.  The  i486 Microprocessor burst
     order is supported.
  b) System cacheability attribute  is provided (SKEN#). SKEN# is used
     to determine whether the current  cycle is cacheable.  If is used
     to  qualify Line  Fill requests.
  c) SHOLD/SHLDA/SBREQ  system  bus  arbitration  mechanism  is  supp-
     orted.  the same  as in  the  i486 Microprocessor.   A Multi  386
     DX/82395DX  cluster  can  share  the  same System  Bus  via  this
     mechanism.
  d) SNENE# output  (Next Near) is provided to  simplify the interface
     to DRAM controllers.   DRAM page size of 2K  is supported.
  e) Fast  HOLD function (SFHOLD#) is provided.   This function allows
     for multiprocessor support.

  f) Cache invalidation  cycles  supported  via SEADS#.   This  is the
     mechanism used to provide cache coherency.

o Full Local Bus/System Bus concurrency is attained by:
  a) Servicing cache read hit cycles on the Local Bus while completing
     a Line Fill  on the System Bus. The data requested  by the 386 DX
     Microprocessor was provided over the  local bus as the first part
     of the Line Fill.
  b) Servicing cache read hit  cycles on the Local Bus while executing
     buffered write  cycles on the system bus.
  c) Servicing  cache read hit cycles  on the Local  Bus while another
     bus master is running (DMA, other 386 DX Microprocessor, 82395DX,
     i486 Microprocessor, etc...) on the System Bus.
  d) Buffering write  cycles on the Local Bus while  the system bus is
     executing other cycles.

o Write protected areas are supported  by the SWP# input. This enables
  caching of ROM space or shadowed ROM space.

o No Post  Input (NPI#)  provided for disabling  of write  buffers per
  cycle. This option supports memory mapped I/O designs.

o A20M# input provided for emulation of 8086 address wrap-around.

o SRAM test mode. in which the TAGRAM and the cache RAM are treated as
  standard SRAM, is provided. A Tristate Output test mode is also pro-
  vided for  system debugging.  in this mode  the 82395DX  is isolated
  from the other devices in the board by floating all its outputs.

o Single chip, 196 lead PQFP package, 1 micron CHMOS-lV technology.
