摘要：
A processor (92) contains a Trace RAM (210) for tracing internal processor signals and operands. A first trace mode separately traces microcode instruction execution and cache controller execution. Selectable groups of signals are traced from both the cache controller (256) and the arithmetic (AX) processor (260). A second trace mode selectively traces full operand words that result from microcode instruction (242). Each microcode instruction word (242) has a trace enable bit (244) that when enabled causes the results of that microcode instruction (242) to be recorded in the Trace RAM (210).
