Patent GB-2293467-A (GB)
Title: Trace analysis of data processing
Inventor: FLYNN DAVID WALTER
IPC: G06F11/28
Filed: 1994-09-20
Abstract: A data processing system provides trace signals on a trace bus 12 to track the address of an instruction code currently being executed and the latest address to which a data access was made. The system incorporates a central processing unit (CPU) core 14 and an instruction pipeline 16 via which instruction codes are fed to the CPU core 14. When a non-sequential instruction code fetch is made, a number of cycles must pass before that non-sequential instruction has made its way along the instruction pipeline 16 to the CPU core 14. This period is utilised to output the address of the non-sequential instruction code fetch upon the trace bus. The multiple cycles available for this allow a time division multiplexing technique to be employed for different portions of the address thereby enabling the trace bus to be narrower. The same technique can be used to output data access addresses using time division multiplexing, but in this case a portion of the time taken to output the address overlaps with execution of some other instruction. When successive accesses are to sequential addresses a trace address increment signal, which may be a single bit, is provided on the trace bus. <IMAGE>
