Abstract

High fan-in/fan-out, low power (1 fJ per gate), high performance computing (HPC) modules are being developed that integrate global (multidimensional) free space `smart' optical interconnects with GaAs DANE technology. This new architecture implements N⁴ global free space optical interconnects coupled with 2-D arrays of N-bit Boolean multiplications by DeMorgan's theorem on wide word fan-ins. `Smart' interconnects provide a high speed inter- module alternative without the power requirements and cross-talk limitations of GaAs circuitry. Selected algorithms such as 64-bit addition can operate at lower power and higher speeds using global technology and GaAs logic. Thus, faster processing can be fully realized which allows for a reduction in pipeline delays.
