Original Abstract Submitted
A system for generating trace packets in a computer system is disclosed. A processor circuit may generate trace information in response to an activation of a trace operation, and a trace circuit, coupled to the processor circuit via a trace interface, may be configured to receive the trace information. The trace circuit may be further configured to generate a plurality of trace packets including a given trace packet that includes an ordered data structure of data sections, wherein an initial data section of the ordered data sections includes a payload, and a final data section of the ordered data sections includes a footer. The trace circuit may be configured, in response to a detection of a load/store instruction in the trace information, to assign a particular index to the load/store instruction from a pool of indices, and generate a data index trace packet using the particular index.
