"The PS3 has a general logic (PPE) PowerPC main controller and 7 SPE "sub-cores." These sub-cores are not general logic cores - unlike Core 2 Duo's "2" cores or 360's "3" cores... Therefore they cannot function independently without the main core "
Not being a fanboy either, just trying to understand the tech a bit. |
Well "sub-cores" is not an official term either I think. the SPE and PPE have different roles in the OS/hardware environment, like which one boots first and which one is the master/slave. The PS3 uses the PPE's support for hypervisor/kernel/user protection model. The kernels in use on SPEs are much simpler as they don't have to run the full real-time OS, they just run tasks.
At the end of the day though the SPEs are just a type of general logic core. Both the PPE and SPE are 3.2GHz dual-issue RISC cores.
