High-throughput Hardware Decoder Implementation for Optical Deep-space Communications

Future space missions will have to meet the demand for very high data rates. Transmission of scientific data and other high-bandwidth communications from deep space back to Earth are among the key challenges coming along with next-generation missions to the Moon and beyond. Optical communication has gained significant interest recently as a promising candidate to offer these high data rates. Co...

Design and Implementation of a High-Throughput CABAC Hardware Accelerator for the HEVC Decoder

HEVC is the new video coding standard of the Joint Collaborative Team on Video Coding. As in its predecessor H.264/AVC, Context-based Adaptive Binary Arithmetic Coding (CABAC) is a throughput bottleneck. This paper presents a hardware acceleration approach for transform coefficient decoding, the most time consuming part of CABAC in HEVC. In addition to a baseline design, a pipelined architectur...

Design and VLSI Implementation of a High Throughput Turbo Decoder

Turbo codes are one of the most efficient error correcting code which approaches the Shannon limit. However the major drawback of turbo codes is its high latency due to its iterative decoding process. The high throughput in turbo decoder can be achieved by parallelizing several Soft Input Soft Output(SISO) units together. In this way, multiple SISO decoders work

High-Throughput Irregular LDPC Decoder

Abstract— This paper presents a high-throughput area-efficient decoder design for the irregular Quasi-Cyclic (QC) Low-Density Parity-Check (LDPC) codes. Two new techniques are proposed, including parallel layered decoding architecture (PLDA) and critical path splitting. PLDA enables parallel processing for all layers by establishing dedicated message passing paths among them. The decoder avoids...
