GreenArrays is shipping its 144-core asynchronous chip that needs little energy (7 pJ/inst). Idle cores use no power (100 nW). Active ones (4 mW) run fast (666 Mips), then wait for communication (idle). Tight coding to minimize instructions execut... Read more

A computer engineer specializing in software, hardware and silicon. Invented the Forth computer language in 1968. Forth, Inc still programs embedded apps from telescope to data base. Designed a Forth gate-array in 1983 and circuit boards to sell it. It's successor (RTX2000) is orbiting Saturn. Filed a valuable asynchronous patent in 1989, embodied in the Sh-Boom microprocessor. Then laid-out fast, low-power Forth microprocessors. In 1998 invented colorForth and used it to position Forth microcomputers into
