**HTK320        386DX Chip Set                                 c:Sep91
***Info:
The  HTK320 chip  set  is a  2-chip, high-performance,  cost-effective
solution for the 80386DX microprocessor. In its minimum configuration,
this  highly  integrated chip  set  requires  only  four external  TTL
devices to implement a fully  compatible IBM PC/AT system at speeds up
to 40 MHz.

The HTK320 is based on Headland’s Bus Architecture and consists of the
HT321-ISA Controller and the  HT322-Memory Control Unit (MCU) packaged
in  two 184-pin plastic  quad flat  packs. Among  its features  are an
on-chip cache controller and internal tag RAM.

Unlike  other  3rd  generation  chip  sets that  have  integral  Cache
Controllers,  the HTK320 integrates  the high-speed  tag RAM  into the
chip  set to  enhance performance  and significantly  reduce component
count  and  manufacturing  cost.   The  direct  mapped  or  2-way  set
associative cache  design supports external  cache sizes of  32K, 64K,
and 128K.

The  HTK320  can  support  Peripheral  Devices such  as  VGA  or  SCSI
controllers on the  local processor bus, or any  3rd party device that
is  designed to  work within  the 386DX  Bus Protocol  and  Timing. By
eliminating the ISA backplane bottleneck, system designers can greatly
improve the  performance of functions such as  graphics generation and
disk access.

The HTK320 incorporates a 4-leve1  deep Write Buffer and performs byte
gathering into  32 bit  accesses to the  DRAM.  This  facilitates real
zero  wait  state  writes  and,   when  coupled  with  the  2-way  set
associative cache, provides enhanced memory performance.

The HTK320 Supports up to 4  banks of DRAM, configurable as 1-4 Banks.
This  flexible memory architecture  allows for  any memory  type, from
256Kb to  16Mb devices,  in any bank.   Maximum system  performance is
achieved  from  the  DRAM   banks  through  various  means,  including
interleave of  Memory Bank  and/or Page, and  CAS before  RAS refresh.
The memory may also be tuned  to its maximum potential through the use
of  extensive   DRAM  timing  Control   Registers,  controls  include,
Precharge time, Access  time on Reads, Active time  on Writes, as well
as CAS  and RAS  delays.  In addition,  further system  performance is
gained  by separate  timing parameters  on the  read and  Write cycles
which  allow  system  designers  to  take  maximum  advantage  of  the
pipelined structure of the chip set.

The  HTK320 also  supports  extensive mapping  registers, which  allow
system designers to take maximum advantage of system memory.  The chip
set supports EMS LIM 4.0, allows  for mixed Shadow/Remap in 16K blocks
between the 640K and 1M boundaries, and eliminates the requirement fer
external  decoding  logic  by  support of  27  Programmable  Non-cache
regions.   With  the'  extensive  HTK320  mapping  capability,  it  is
feasible  to seamlessly  place  3rd  party devices  on  the local  bus
without  the  need  for  external  TTL  support.  The  HTK320  Mapping
structure provides  for a single 8-bit  EPROM to be used  for both the
system  and Video  BIOS, further  reducing the  system chip  count and
cost.
