Hardware-enabled instruction tracing

摘要

A data processing system includes an instruction pipeline, including one or more execution units that execute instructions and an instruction sequencing unit that dispatches instructions to the execution units for execution. The data processing system further includes a memory controller for a memory containing an instruction trace log and an interconnect coupled to the instruction pipeline and to the memory controller. The interconnect transmits to the memory controller for storage in the instruction trace log instructions processed within the instruction pipeline.
