Like most technology firms, Apple has been home to many successes, and some spectacular defeats. One failure was Project Aquarius. At the dawn of the RISC era, before ARM architecture was “discovered” in Cupertino, engineers were hunkered over a Cray X-MP/48. The objective was to design Apple’s own quad core RISC processor to speed up the Macintosh.
As if designing an instruction set, execution units, and pipeline is not hard enough, getting four cores to work together is more than simply a matter of cloning and connecting.
