Abstract
A computer system operates for pipe-line processing, and includes a cache memory and a tracing circuit for tracing the operation of the pipe-line processor for developing the computer system. The pipe-line processing is executed in separate stage blocks, and the trace data are supplied to the tracing circuit through a dedicated tracing bus at the final stage of the pipe-line processing. If the data is hit in the cache memory, the trace data can be provided to the tracing circuit without losing real time processing.
