Abstract

The Optoelectronic Viterbi Decoder (OVD) in [1] is proposed to alleviate the interconnect bottleneck prevalent in high speed, fully parallel, multi-chip Viterbi decoders used in digital communication systems to decode long constraint length convolutional codes. The OVD utilizes a reflective optical system comprised of a macro-lens array and a mirror to globally interconnect VCSEL/MSM PD based smart pixel arrays distributed across multiple OEIC’s on a PCB or MCM. Smart pixels that possess identical functionality are clustered on the chips and interconnected with VLSI interconnects. This hybrid approach of optical/electrical interconnects overcomes the interconnect density and speed limitations of traditional VLSI approaches to long constraint length decoding and provides high decoder throughput and trace-back speed by maintaining on-chip speeds between chips. This paper presents a model for the OEIC’s of the OVD, and estimates decoder speed by utilizing interconnect prediction [2] and stochastic cycle time models [3].
