AUTOMATIC CONTROL OF MULTIPLE ARITHMETIC/LOGIC SIMD UNITS

摘要

There is provided a method of performing single instruction multiple data (SlMD) operations. The method comprises storing a plurality of arrays in memory for performing SIMD operations thereon; determining a total number of SIMD operations to be performed on the plurality of arrays; loading a counter with the total number of SIMD operations to be performed on the plurality of arrays; enabling a plurality of arithmetic logic units (ALUs) to perform a first number of operations on first elements of the plurality of arrays; performing the first number of operations on first elements of the plurality of arrays using the plurality of ALUs; decrementing the counter by the first number of operations to provide a remaining number of operations; and enabling a number of the plurality of ALUs to perform the remaining number of operations on second elements of the plurality of arrays.
