***Info:
The  VT82C580VP Apollo-VP  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. CPU and cache interface is
supported up to 66Mhz CPU  external bus speed (with CPU internal speed
up  to  200Mhz  and  above).  The  CPU,  DRAM  and  PCI  bus  are  all
independently powered  so that each of the  bus can be run  at 3.3v or
5v, independently. The ISA bus always runs at 5v.

The VT82C580VP chip set  consists of the VT82C585VP system controller,
the VT82C586  PCI to ISA bridge,  and two instances  of the VT82C587VP
data  buffers. The  CPU bus  is minimally  loaded with  only  the CPU,
secondary cache and the chip  set. The VT82C587VP data buffers isolate
the CPU bus from the DRAM and  PCI bus so that CPU and cache operation
may  run  reliably  at   the  high  frequencies  demanded  by  today's
processors. The  VT82C585VP contains arbitration logic  to support the
UMA (unified  memory architecture) with video/GUI  products from major
video  vendors.  Multiple  deep  FIFOs (thirty-two  double words)  are
included  between multiple  data paths  to allow  efficient concurrent
operation  and  DRAM utilization.   The  VT82C586  PCI  to ISA  bridge
includes  integrated  206-style  IPC  (DMA, interrupt  controller  and
timer),  integrated  keyboard   controller  with  PS2  mouse  support,
integrated DS12885 style  real time clock with extended  128 byte CMOS
RAM, integrated master mode  enhanced IDE controller with full scatter
and  gather  capability, and  integrated  USB  (universal serial  bus)
interface with root hub and  two function ports with built-in physical
layer transceiver. A complete main  board can be implemented with only
six  TTLs. Please refer  to Figure  1 [see  datasheet] for  the system
block diagram.
