Abstract:
1. A method comprising: receiving from a single, integrated memory, current and previous iterations of Log Likelihood Ratio (“LLR”) parameters for a current iteration of a Low-Density Parity-Check code (“LDPC code”) error-correcting process; performing an LDPC code error-correcting algorithm using the current and previous iterations of LLR parameters; overwriting the previous iteration of LLR parameters with a now-current iteration of LLR parameters and treating the current iteration of LLR parameters as a now-previous iteration of LLR parameters; after overwriting the previous iteration of LLR parameters, receiving both the now-current and the now-previous iterations of LLR parameters for the now-current iteration of the LDPC code error-correcting process from the single, integrated memory; and performing the LDPC code error-correcting algorithm using the now-current and the now-previous iterations of LLR parameters.
