yes.

cos, atan2, irsqrt, yuv2rgb, zbuffer, these are all to be added to *POWER*
ISA, as *native* POWER opcodes.

not even as a separate core disconnected from the POWER core, *actually*
add an *actual* atan2 ALU pipeline to the *one* processor core and an atan2
opcode to the *POWER* instruction decoder.

the CPU *is* the GPU.

the GPU *is* the CPU.
