Partial-parallel implementation of LDPC (Low Density Parity Check) decoder. A novel approach is presented by which a selected number of cycles is performed during each of bit node processing and check node processing when performing error correction decoding of an LDPC coded signal. The number of cycles of each of bit node processing and check node processing need not be the same. At least one functional block, component, portion of hardware, or calculation can be used during both of the bit node processing and check node processing thereby conserving space with an efficient use of processing resources. At a minimum, a semi-parallel approach can be performed where 2 cycles are performed during each of bit node processing and check node processing. Alternatively, more than 2 cycles can be performed for each of bit node processing and check node processing.
