Metaflow Technologies was a La Jolla, California-based microprocessor design company. It was founded in 1988 by Val Popescu, Merle Schultz, Gary Gibson, John Spracklen, and Bruce Lightner. The company is not well known to the general public as none of its designs were ever manufactured in volume. The company is known within the computer architecture community as it published articles in technical journals in the early 1990s that described how an out-of-order with speculative execution CPU might be designed. This was one of the first publicly disclosed OoO designs from a non-academic source.
