One SPE is disabled to increase yield, so the PS3 can have at most 9 threads runnings at the same time (2 from PPE and 7 from SPE). Note that one SPE is reserved for the hypervisor, so PS3 programs can take advantage of 8 threads. Both the PPE and SPE of the Cell are 64 bit, and manipulate data in Big Endian. | ||
