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-653/658 provides two lev-
els of cache memory; level one is internal to the CPU (see CPU Chip on p. 1-2), and
level two (external cache) is 512 KB of high-speed cache memory.
