> It was designed to be completely different from previous console CPUs. Sure, but they used a PowerPC core with specialized SIMD processors that they then extensively documented: https://arcb.csc.ncsu.edu/~mueller/cluster/ps3/SDK3.0/docs/arch/SPU_ISA_v1.2_27Jan2007_pub.pdf https://arcb.csc.ncsu.edu/~mueller/cluster/ps3/SDK3.0/docs/a... If they hadn't done the latter, it would probably have taken a lot longer to reverse engineer. It also would have made it near impossible for developers to code effectively for it, however.
