ARCHITECTURE AND EXECUTION FOR EFFICIENT MIXED PRECISION COMPUTATIONS IN SINGLE INSTRUCTION MULTIPLE DATA/THREAD (SIMD/T) DEVICES

摘要

A method for improving power, performance, area (PPA) for mixed precision computations in a processing environment. The method includes determining a braiding factor as a number of units of work encoded into a physical thread. A value of the braiding factor is determined based on a mix of precision requirements presented for individual units of work. Units of work are classified as instructions for applied code transformation based on associated precision requirements for the processing environment. Instruction inputs from specified registers are packed together into a destination register according to the determined value of the braiding factor. The packed instructions presented in vector form are executed with an instruction set architecture configured for executing packed instructions of different precisions.
