SUBNANOSECOND ARITHMETIC for 1990-1993

Michael J. Flynn

Abstract:

The Stanford Nanosecond Arithmetic Project is targeted at realizing an arithmetic processor with performance approximately an order of magnitude faster than currently avaiable technology. The realization of SNAP is predicated on an interdisciplinary approach and effort spanning research in algorithms, data representation, CAD, circuits and devices, and packaging. SNAP is visualized as an arithmetic coprocessor implemented on an active substrate containing several chips, each of which realize a particular arithmetic function. We have fabricated a number of prototype die.

SNAP-the Stanford subnanosecond arithmetic processor-is an interdisciplinary effort to develop theory, tools, and technology realizing an arithmetic processor with execution rates under 1 ns. During the course of our SNAP project, we have made significant progress toward accomplishing a gigaflop (a billion floating-point arithmetic operations per second) computing element. This report is an extended abstract summarizing the SNAP results.
