GZIP decompression accelerator is fabricated in 14nm CMOS, achieving industry-leading 20.5Gbps throughput. The design features out-of-order speculative Huffman decoder to break the fundamental serial dependency resulting in 69% higher decode throughput. The hybrid dual-path decoder provides 2.3× higher performance with multi-write enabled register-file array increasing decompression throughput by up to 41%. The arithmetic-architecture-circuit co-optimized design operates at 1.4GHz at 750mV, 25°C with peak measured energy-efficiency of 1.86pJ/code at 280mV, 2.7× higher than previously reported implementations. |
