**CS8233 PEAK/386 AT (Cached) (82C311/82C315/82C316) c:Dec90
***Info:
Introduction.
The CS8233 PEAK/386 AT CHIPSet is a three chip VLSI implementation of
most of the system logic required to implement a CACHE BASED iAPX
386DX based system. The CHIPSet is designed to offer a 100% PC AT
compatible integrated solution. The flexible architecture of the
CHIPSet allows it to be used in any iAPX386DX based system design,
such as CAD/CAE workstations, office systems, industrial and financial
transaction systems. The CS8233 PEAK/386 AT CHIPSet provides a
complete CACHE BASED 386/AT system using only 19 components plus
memory device. The CS8233 PEAK/386 AT CHIPSet consists of one 82C31l
CPU/Cache/DRAM Controller, one 82C315 Bus Controller, and one 82C316
Peripherals Controller. The CHIPSet supports a local CPU bus, a 32-bit
system memory bus, and AT buses as shown in the system diagram [see
data sheet]. The 82C311, 82C315, and 82C316 are all available in 160
pin PFP package.
The 82C311 CPU/Cache/DRAM Controller
The 82C311 provides the generation and synchronization of control
signals for all buses. The 82C311 also supports an independent AT bus
clock, and allows selection of different processor and AT bus clock
speed.
The 82C311 contains a high performance and high integration Cache/DRAM
controller designed to interface directly to the 80386DX micro-
processor. By integrating Cache/DRAM control functions on-chip,
simultaneous activation of cache and DRAM accesses minimize the cache
miss cycle penalty.
The 82C311 Cache Controller supports a two-way set associative cache
architecture and cache sizes of either 32KB, 64KB or 128KB. It
implements a buffered-write through scheme and a Least Recently Used
(LRU) replacement algorithm.
The 82C311 also has hardware support to allow the user to designate up
to four blocks (of variable size from 4KB to 4MB) of main memory as
non-cacheable address space. This feature is important for
compatibility issues when operating in a multi-processing LAN
environment, dual-port memory environment, and non-caching of video
RAM. In addition, this feature eliminates the need to use very fast
PALS externally to decode non-cacheable regions and gives the user
much more flexibility.
82C315 Bus Controller
The 82C315 Bus Controller contains the data buffers used to interface
between the local, system memory and AT data buses. In addition to
having high current drive, they also perform the conversion necessary
between the different sized data paths. The 82C315 also includes all
the interface logic required to directly interface to the 80387DX and
Weitek 3167 co-processors with no additional discrete logic required.
82C316 Peripheral Controller
The 82C316 Peripheral Controller contains the address buffers used to
interface between all address buses and the addresses needed for
proper data path conversion. In addition to integrating a variety of
TTL/SSI interface logic, the 82C316 includes the equivalent of the
82C206 Integrated Peripheral Controller (IPC). The IPC section
contains:
o Two (2) 82387 DMA controllers [sic, should be 8237A?]
o Two (2) 8259 interrupt controllers
o One (1) 8254 timer/counter
o One (1) MC146818 real time clock
o One (1) memory mapper
