Abstract
Tracing command execution in a data processing system having a host processor and a co-processor. The host processor maintains a record of a plurality of commands for the co-processor, storing each of the plurality of commands is stored in a command queue. Hardware trace logic is provided to store one or more events based, at least in part, on transfer of the plurality of commands to a small memory. Software is executed to store the one or more events to a main memory, wherein the one or more events are aggregated into a single memory trace within the main memory.
