Is Power PC a RISC cpu?
- mmrezaie 7y agoThe name "POWER" was originally presented as an acronym for "Performance Optimization With Enhanced RISC" [1]. So yes. [1] https://en.wikipedia.org/wiki/IBM_POWER_microprocessors https://en.wikipedia.org/wiki/IBM_POWER_microprocessors
- Symmetry 7y agoYes. IIRC its main break with RISC orthodoxy is storing comparison results in one of a small number, 8 I think, of special purpose registers and then specifying which of those branches to look at in conditional operations like branches.
