Design of a High-Speed Asynchronous Turbo Decoder
This paper explores the advantages of high performance asynchronous circuits in a semi-custom standard cell environment for high-throughput turbo coding. Turbo codes are high-performance error correction codes used in applications where maximal information transfer is needed over a limitedbandwidth communication link in the presence of data corrupting noise. Specifically we designed an asynchronous high-speed Turbo decoder that can be potentially used for new wireless communications protocols with close to OC-12 throughputs. The design has been implemented using a new static single-track-full-buffer (SSTFB) standard cell library in IBM 0.18µm technology that provides low latency, fast cycle-time, and more robustness to noise than previously studied single-track full-buffer technology (STFB). A high-speed synchronous counterpart using the same high-speed architecture is designed in the same technology for comparison. The results demonstrate that for a variety of network constraints, t...
