A Novel Search-Based Compute-in-Memory Minimum Values Generation Scheme for Low-Complexity LDPC Min-Sum Decoding

The generation of the minimum values (the first two minima and the index of the minimum) of numerous variable-to-check messages (V2CM) is the major bottleneck in efficient min-sum decoding of low-density parity-check (LDPC) codes. This brief proposed a novel search-based compute-in-memory (CIM) base...
