In one embodiment, a reconfigurable minimum operator has two five-bit non-reconfigurable minimum operators and is selectively configurable to operate in a five- or ten-bit mode. In five-bit mode, the first non-reconfigurable minimum operator determines whether a first five-bit message is less than a second five-bit message, and the second non-reconfigurable minimum operator determines whether a third five-bit message is less than a fourth five-bit message. In ten-bit mode, the first non-reconfigurable minimum operator determines whether a first half of a first ten-bit message is less than a first half of a second ten-bit message, and the second non-reconfigurable minimum operator determines whether a second half of the first ten-bit message is less than a second half of the second ten-bit message. The reconfigurable minimum operator determines whether the first ten-bit message is less than the second ten-bit message based on the comparisons of the first and second non-reconfigurable minimum operators.
