I mean are they totally independant and able to access the system or are they just sub processors which use the main core for scheduling and essentially just run encapsulated processes and submit the results to the main core CPU. |
As far as I understand the architecture the scheduling happens on the PPE, which communicates events to the SPEs over some dedicated channels. Other channels can be used by the SPEs for DMA communication, so once they start crunching numbers they can work quite indipendently on a chunk of main memory.
