LOW POWER LOW-DENSITY PARITY-CHECK DECODING

摘要

In general, a minimum determination capability, adapted for determining one or more minimum values from a set of values, is provided. The minimum determination capability may enable, for a set of values, determination of a first minimum value representing a smallest value of the set of values and a second minimum value representing an approximation of a next-smallest value of the set of values. The minimum determination capability may enable, for a set of values where each of the values is represented as a respective set of bits at a respective set of bit positions, determination of a minimum value of the set of values based on a set of bitwise comparisons performed for the respective bit positions of the values.

1. An apparatus, comprising:
a set of modules configured to:
receive a set of values;evaluate a first portion of the values to determine a magnitude of a minimum value of the first portion of the values;evaluate a second portion of the values to determine a magnitude of a minimum value of the second portion of the values; anddetermine, based on a comparison of the magnitude of the minimum value of the first portion of the values and the magnitude of the minimum value of the second portion of the values, a first minimum value representing a magnitude of a smallest value of the set of values and a second minimum value representing an approximation of a magnitude of a next-smallest value of the set of values.
