***Info:
The CS8231 TURBO CACHE BASED 386/AT CHIPSet is a seven chip VLSI
implementation of most of the system logic to implement a CACHE BASED
iAPX 386 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 iAPX386 based system design, such
as CAD/CAE workstations, office systems, industrial and financial
transaction systems.
The CS8231 CHIPSet combined with CHIP's 82C206, Integrated Peripherals
Controller, provides a complete PC AT compatible system using only 40
components plus memory devices.
The CS8231 CHIPSet consists of one 82C301 Bus Controller, one 82C307
Integrated CACHE/DRAM controller, one each of 82A303 and 82A304
Address Bus Interfaces, two 82B305 Data Bus Interfaces, and a 82A306
Control Signal Buffer.
The CHIPSet supports a local CPU bus, a 32-bit system memory bus, and
AT buses as shown in the system diagram below. The 82C301 and 82A306
provide the generation and synchronization of control signals for all
buses. The 82C301 also supports an independent AT bus clock, and
allows for dynamic selection of the processor clock between the 16M
Hz, 20MHz, or 25MHz clocks and the AT bus clock. The 82A306 provides
buffers for bus control signals in addition to other miscellaneous
logic functions.
The 82C307 is a high performance and high integration CACHE/DRAM
controller designed to interface directly to the 80386 micro-
processor. It maintains frequently accessed code and data in high
speed memory, allowing the 80386 to operate at its maximum rated freq-
uency with near zero waitstates. By integrating DRAM control func-
tions on-chip, it supports simultaneous activation of cache and DRAM
access, thereby minimizing the cache miss cycle penalty. It has
hardware support to allow the user to designate up to four blocks (of
variable size from 2KB to 128KB) of main memory as non-cacheable
address space. This feature is important for compatibility issues
when operating in a multiprocessing or LAN environment, or where dual-
port memory is used, and to designate certain regions of video RAM as
non-cacheable. This feature eliminates the need to use very fast PALs
externally to decode non-cacheable regions and gives the user much
more flexibility. Optional EDC support logic is integrated on to the
82C307 which allows it to interface to any of the generically
available 32-bit Error Detection and Correction Circuits to realize a
highly reliable memory subsystem.
Cache coherency is maintained during DMA cycles by channeling all acc-
esses through the cache controller logic. During DMA read operations,
the cache RAM is not accessed and data is retrieved from the main
memory. During DMA write operations, if a cache hit is detected, the
cache RAM is updated and the corresponding tag validated. Cache
coherency is maintained at all times, with no performance penalty.
The 82C307 is available in a 100 pin PFP package.
The 82A303 and 32A304 interface between all address buses, and the
addresses needed for proper data path conversion. Two 828305 are 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.
