Abstract
A system, apparatus, and method for writing trace data to storage. Trace data is captured from one or more processors, and then the trace data is written to a trace buffer. The trace data includes program counters of instructions executed by the processors and other debug data. A direct memory access (DMA) controller in a non-real-time block of the system reads trace data from the trace buffer and then writes the trace data to memory via a non-real-time port of a memory controller.
