Summary Chuck Moore discusses what it takes to program a 144-core asynchronous chip that consumes only 7 pJ/inst, the idle cores taking just 100 nW while the active ones need 4mW running at 666 Mips: tight coding to minimize the number of instructions executed, reducing instruction fetches, transistor switching, and duty cycle.

Bio Chuck Moore is 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 database. Designed a Forth gate-array in 1983 and circuit boards to sell it. Its successor (RTX2000) is orbiting Saturn. Filed a valuable asynchronous patent in 1989, embodied in the Sh-Boom microprocessor.

About the conference Strange Loop is a multi-disciplinary conference that aims to bring together the developers and thinkers building tomorrow's technology in fields such as emerging languages, alternative databases, concurrency, distributed systems, mobile development, and the web.
