Method and apparatus for identifying selected values from among a set of values

摘要

The present invention is directed toward identifying selected values from among a set of values. In accordance with an embodiment, a method of identifying two selected values from among a plurality of values comprises: partitioning the plurality of values into pairs of values; for each pair of values, using a comparator to select one of the two values to form a vector from the selected value of each pair; and applying the vector to a hardware unit that identifies first and second extreme values from among the values of the vector.

1. A method of identifying two selected values from among a plurality of values, comprising steps of:
partitioning the plurality of values into pairs of values; for each pair of values, using a hardware comparator device within an error correction decoder system to select one of the two values to form a vector of values that includes the selected value of each pair, wherein the vector of values does not necessarily include a second most extreme value of the plurality of values; and applying the vector to inputs of a hardware selection circuitry that identifies first and second extreme values from among the values of the vector.
