Abstract:
Systems and methods for generating DMA transaction trace records are described. One example system includes a controller that includes a trace module. The trace module receives transfer requests for direct memory access channels, receives timestamps indicative of a transfer request time, generates trace records, wherein each trace record includes a respective timestamp indicative of a transfer request time, generates save commands, and delivers the trace records and the save commands as outputs. The system includes a storage module for saving trace records.
