***Info:
The VT82C570M Apollo Master is a high performance, cost-effective and
energy efficient chip set for the implementation of PCI/ISA desktop
and notebook personal computer systems based on the 64-bit
P54C/Pentium/K5/M1 super-scalar processors. Either 3.3v or 5v CPU and
cache interface is supported up to 66Mhz CPU external bus speed (with
CPU internal speed up to 150Mhz and above). In either case, DRAM, PCI
and ISA bus runs at 5v voltage level.
The VT82C570M chip set consists of the VT82C575M system controller,
the VT82C576M PCI bus controller with integrated master mode
Enhanced-IDE controller, and two instances of the VT82C577M data
buffers. The CPU bus is minimally loaded with only the CPU, secondary
cache and the chip set. The VT82C577M data buffers isolate the CPU bus
from the DRAM, PCI and ISA bus so that CPU and cache operation may run
reliably at the high frequencies demanded by today's processors. The
chip set also interfaces directly with the VT82C416 integrated clock
generator, real time clock with extended CMOS (128 byte) and keyboard
controller with PS2 mouse support. A complete main board can be
implemented with only ten TTLs. Please refer to Figure 1 for the
system block diagram.
The VT82C570M supports eight banks of DRAMs up to 512MB. The DRAM
controller supports Standard Page Mode DRAM, EDO-DRAM and Burst
EDO-DRAM in a flexible mixed/match manner. The eight banks of DRAM
are grouped into four pairs with an arbitrary mixture of
256K/512K/1M/2M/4M/8M/16MxN DRAMs. Zero, one or both banks may be
populated in each pair with either 32bit or 64bit data width.
The secondary (L2) cache is based on Burst Synchronous (Pipelined or
non-pipelined) SRAM, asynchronous SRAM or cache module from 128KB to
2MB. For burst synchronous SRAMs, 3-1-1-1 timing can be achieved for
both read and write transactions at 66Mhz. For standard SRAMs, 3-2-2-2
and 4-2-2-2 timing can be achieved for interleaved read and write
transactions at 66Mhz. Four levels of CPU/cache to DRAM write buffers
with concurrent write-back capability are included in the VT82C577M
data buffer chips to speed up the cache read and write miss
cycles. For primary cache fill cycles that result in secondary cache
misses, the primary and secondary caches are filled up concurrently to
further enhance the performance.
