**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.
