Abstract

Official abstract text for this publication.

A method to compare between a first number and a second number includes the steps of storing the first number in a first row of an associative memory array, storing a two's complement representation of the second number in a second row of the associative memory array wherein bit i of the second number is stored in a same column of the associative memory array as bit i of the first number, concurrently performing a carry save operation on a plurality of columns of the associative memory array to create a sum and a carry, predicting a value of a carry out bit without adding the sum and the carry, and indicating that the first number is smaller than the second number if the value of the carry out bit is 1.

First claim

Opening claim text (preview).

What is claimed is: 1. A method to compare between a first number and a second number, the method comprising: storing said first number in a first row of an associative memory array; storing a two's complement representation of said second number in a second row of said associative memory array wherein bit i of said second number is stored in a same column of said associative memory array as bit i of said first number; concurrently performing a carry save operation on a plurality of columns of said associative memory array to create a sum and a carry; predicting a value of a carry out bit without adding said sum and said carry; and indicating that said first number is smaller than said second number if said value of said carry out bit is 1.
