A scalable ASIP for BP Polar decoding with multiple code lengths

In this paper, we propose a flexible scalable BP Polar decoding application-specific instruction set processor (PASIP) that supports multiple code lengths (64 to 4096) and any code rates. High throughputs and sufficient programmability are achieved by the single-instruction-multiple-data (SIMD) based architecture and specially designed Polar decoding acceleration instructions. The synthesis result using 65 nm CMOS technology shows that the total area of PASIP is 2.71 mm2. PASIP provides the maximum throughput of 1563 Mbps (for N = 1024) at the work frequency of 400MHz. The comparison with state-of-art Polar decoders reveals PASIP’s high area efficiency.
