Publication number: 20240097703Abstract: A lossless data compressor prevents normalization overruns on-the-fly as symbol occurrence counts are rounded to generate symbol frequencies, allowing an encoding table generator to generate encoding table entries without waiting for the symbol frequency table to finish filling. Rounding errors are accumulated as symbols are normalized and compensated for by reducing a symbol frequency when the symbol frequency is at least 2 and the accumulated errors have exceeded a threshold. The symbol frequency is also reduced when the number of remaining states in the encoding table is insufficient for a number of remaining unprocessed symbols and states for a current encoding table entry. Since error compensation occurs as symbols are being normalized, encoding table generation is not forced to wait for all symbols in the block to be processed, reducing latency. Three pipeline stages can operate on three input blocks: symbol counting, normalization/error compensation/encoding table generation, and data encoding.Type: ApplicationFiled: September 20, 2022Publication date: March 21, 2024Inventors: Hing-Mo LAM, Hailiang LI, Ho Yu WONG

Patent number: 11575390Abstract: Systems and methods which provide parallel processing of multiple message bundles for a codeword undergoing a decoding process are described. Embodiments provide low-latency segmented quasi-cyclic low-density parity-check (QC-LDDC) decoder configurations in which decoding process tasks are allocated to different segments of the low-latency segmented QC-LDPC decoder for processing multiple bundles of messages in parallel. A segmented shifter of a low-latency segmented QC-LDPC decoder implementation may be configured to process multiple bundles of a plurality of edge paths in parallel. Multiple bundles of messages of a same check node cluster (CNC) are processed in parallel. Additionally, multiple bundles of messages of a plurality of CNCs are processed in parallel.Type: GrantFiled: July 2, 2021Date of Patent: February 7, 2023Assignee: Hong Kong Applied Science and Technology Research Insitute Co., Ltd.Inventors: Hing-Mo Lam, Hin-Tat Chan, Ying-Lun Tsui, Zhonghui Zhang, Man-Wai Kwan, Kong-Chau Tsang

Patent number: 10877729Abstract: Systems and methods that provide reconfigurable shifter configurations supporting multiple instruction, multiple data (MIMD) are described. Shifters implemented according to embodiments support multiple data shifts with respect to an instance of data shifting, wherein multiple individual different data shifts are implemented at a time in parallel. Reconfigurable segmented scalable shifters of embodiments, in addition being reconfigurable for scalability in supporting data shifting with respect to various bit lengths of data, are configured to support data shifting of differing bit lengths in parallel. The data shifters of embodiments implement segmentation for facilitating data shifting with respect to differing bit lengths. Different data shift commands may be provided with respect to each such segment, thereby facilitating multiple data shifts in parallel with respect to various bit lengths of data.Type: GrantFiled: January 31, 2019Date of Patent: December 29, 2020Assignee: Hong Kong Applied Science and Technology Research Institute Co., Ltd.Inventors: Hing-Mo Lam, Man-Wai Kwan, Ching-Hong Leung, Kong-Chau Tsang
