Parallel arrangement of serial concatenated convolutional code decoders with optimized organization of data for efficient use of memory resources

摘要

A decoding system (100) is provided. The decoding system is comprised of two or more serial concatenated convolution code (SCCC) decoders (102₁-102_N) operating in parallel. The SCCC decoders are configured to concurrently decode codebocks which have been encoded using a convolutional code. The decoding system is also comprised of a single common address generator (108) and data store (114). The address generator is responsive to requests for data needed by two or more of the SCCC decoders for permutation and depermutation. The data store is comprised of two or more memory blocks (116₁-116_K). The SCCC decoders concurrently generate requests for two or more different data types. Selected ones of the different data types are exclusively stored in different ones of the memory blocks. Selected ones of the different data types are comprised of data which is requested at the same time by a particular one of the SCCC decoders.
