Abstract

Vector processing engines (VPEs) employing format conversion circuitry in data flow paths between vector data memory and execution units to provide in-flight format-converting of input vector data to execution units for vector processing operations are disclosed. Related vector processor systems and methods are also disclosed. Format conversion circuitry is provided in data flow paths between vector data memory and execution units in the VPE. The format conversion circuitry is configured to convert input vector data sample sets fetched from vector data memory in-flight while the input vector data sample sets are being provided over the data flow paths to the execution units to be processed. In this manner, format conversion of the input vector data sample sets does not require pre-processing, storage, and re-fetching from vector data memory, thereby reducing power consumption and not limiting efficiency of the data flow paths by format conversion pre-processing delays.
