Abstract
There are provided a method, an apparatus and a computer program product for reducing power consumption in an iterative decoder. The apparatus includes a memory device and an iteration termination device. The memory device is for storing a bit number difference indicating a number of bits that are different between a decoded codeword for a current iteration and a decoded codeword for a previous iteration, for each iteration of the iterative decoder prior to a maximum number of iterations. The iteration termination device is for comparing the bit number difference to a pre-specified bit number difference threshold value, incrementing a confidence value when the bit number difference exceeds the pre-specified bit number difference threshold value, and terminating further iterations of the iterative decoder when the confidence value exceeds a pre-specified confidence threshold value.
