**SL82C470 'Mozart' 486/386 EISA chipset c:Dec91
***Info:
The SL82C470 chip set provides a very high performance. highly inte-
grated and cost-effective implementation for personal computer systems
based on the standard EISA bus. It supports both 386DX and 486DX/SX
CPUs over the entire performance range, from 20Mhz to 50Mhz. The chip
set can operate in either "conventional" or "concurrent" config-
uration. Under the conventional configuration, the cache subsystem is
dedicated to bus snooping when a DMA or master device becomes active.
Under the concurrent configuration, the CPU-cache operation continues
while bus snooping is performed for the DMA or master device to
explore maximum concurrency between the CPU and the EISA bus. Only
ten TTLs are required for a complete motherboard design under the
conventional configuration in addition to the chip set and memory
devices. Five additional TTLs are required for the concurrent
configuration. A complete EISA system of either configuration can be
easily implemented on a baby AT sized motherboard.
The SL82C470 chip set consists of three 160-pin PQFP devices: the
SL82C471 integrated cache/DRAM controller, the SL82C472 EISA bus
controller and the SL82C473 DMA controller.
SL820471 Cache/DRAM Controller
The SL82C47l Cache/DRAM controller controls the cache and DRAM
accesses from the CPU, EISA/ISA masters and DMA devices. The chip
adapts a write-back cache scheme to minimize the interference between
the CPU-cache and DMA/master during their concurrent operations. The
cache size ranges from 64KB to 1MB with advanced features such as
2-1-1-1 burst line fill. Snoop-filtering, local bus support and
programmable non-cacheable and write-protected regions. The page mode
DRAM controller supports 1 to 4 banks of DRAMS up to 256MB. A mixture
of 256KB, 1MB. 4MB and 16MB DRAMs is supported. The video and system
BIOS can be shadowed or cached independently. The cache-DRAM
subsystem allows zero wait state burst mode DMA transfers to take full
advantage of the high bandwidth of the EISA bus.
The DRAM data bus can either be connected directly to the CPU local
bus or be buffered externally, The control signals for the external
buffers are generated by the SL82C471.
SL82C472 EISA Bus Controller
The SL82C472 EISA bus controller translates bus control signals
between the CPU, EISA/ISA and DMA masters and slaves. The chip also
includes buffers and byte/word swap logic between the CPU (or DRAM)
and the EISA bus. The bus conversion and data alignment are performed
automatically.
The SL82C472 includes two 8259 interrupt controllers and four 8254
timer channels modified for 100% EISA compatibility. The chip also
includes parity generation and check logic and NMI and timeout logic.
SL82C473 EISA DMA Controller
The SL82C473 DMA controller implements seven EISA DMA channels. the
system arbiter and the co-processor interface logic. The DMA control-
ler supports compatible type A, type B and type C (burst) mode
operations with the buffer chaining capability. The multilevel
rotating priority arbitration with fail-safe timeout is implemented
for the system arbiter. Six sets of slot-specific master handshake
signals (MACK and MREQ) are provided directly without any external
components.
The address latches and buffers for the EISA bus are also included in
the SL82C473.
