Abstract

A system and method to record and trace data exchanges between cooperating hardware unit operations and software unit operations, providing an efficient mechanism to trace back to a root cause point from an observed failure point in a series of executed instructions performed within a data processing system. A data debug memory records information pertaining to each system memory access performed by instructions executed by the hardware and software units into separate memory information blocks. Linked relationships are created between certain ones of the memory information blocks to represent data dependencies that occurred between the instructions. These linked relationships may then be utilized to generate lists that map the various data dependencies between the executed instructions.
