Abstract
An apparatus includes a processor to determine an extremum among a series of values that are successively provided to a first register and a second register. The processor is configured to execute a single cycle search instruction, including compare a value in the first register with a value in a first accumulator, and store an extremum of the two values in the first accumulator; and compare a value in the second register with a value in a second accumulator, and store an extremum of the two values in the second accumulator. The processor is configured to execute a single cycle select instruction, including compare the value in the first accumulator with the value in the second accumulator, and store an extremum of the two values in the first accumulator, the extremum stored in the first accumulator representing the extremum of the series of numbers.
