A processing unit (PU) retrieves a file from system memory and loads it
into its internal memory. The PU extracts a processor type from the
file's header which identifies whether the file should execute on the PU
or a synergistic processing unit (SPU). If an SPU should execute the
file, the PU DMA's the file to the SPU for execution. In one embodiment,
the file is a combined file which includes both PU and SPU code. In this
embodiment, the PU identifies one or more section headers included in the
file which indicates embedded SPU code within the combined file. In this
embodiment, the PU extracts the SPU code from the combined file and DMA's
the extracted code to an SPU for execution.
