**82495XP/490XP Cache Controller / Cache RAM (for i860)       06/05/91
***Notes:...
***Info:
The Intel 82495XP cache controller and 82490XP cache RAM, when coupled
with a user-implemented memory  bus controller, provide a second-level
cache  subsystem  that eliminates  the  memory  latency and  bandwidth
bottleneck for  a wide  range of multiprocessor  systems based  on the
i860 XP  microprocessor. The CPU  interface is optimized to  serve the
i860  XP microprocessor  with zero  wait  states at  up to  50 MHz.  A
secondary cache  built from the  82495XP and 82490XP isolates  the CPU
from  the memory subsystem;  the memory  can run  slower and  follow a
different protocol than the i860 XP microprocessor.
