Abstract

In a pipelined data processor (11), an address pipeline (39, 41) is provided to hold the addresses of the instructions presently in the instruction pipeline (23, 25) . The address pipeline facilitates tracing only executed instructions, and permits stopping the data processor during a branch delay slot without losing the branch information.
