Memory Cache Submenu

Enabling cache increases CPU performance by holding data most recently accessed in a
special high-speed static RAM area called cache. The XVME-655 provides two levels of
cache memory; level one is 16 Kbytes internal to the Pentium processor, and level two,
or external cache, is the cache-on-a-stick site (COAST) which can accommodate 256 or
512 Kbytes of high-speed cache memory.
