Processor with maximum and minimum instructions

摘要

A method of operating a processor in a variable bit-length environment by performing a maximum limit function and minimum limit function. The method comprises accessing a most significant portion of a first number in a first register, wherein the most significant portion of the first number includes a first value. The method also includes accessing a most significant portion of a second number that includes a maximum/minimum limit, wherein the most significant portion of the second number includes a second value. The method includes changing the most significant portion of the first number to match the most significant portion of the second number if the first value is greater/less than the second value and storing the most significant portion of the first number in the first register.
