ABSTRACT:
A multi-cache memory system resides on-chip with a system interface to external memory. A general cache memory holds frequently used data and OPCODES for delivery to a processor in one clock cycle. A microcode cache holds frequently used microcode instruction words for delivery to the processor in one clock cycle. Both general and microcode cache memories operate to replace less frequently used OPCODES, data words, and microcode instruction words, with more frequently used words.
