Abstract

A method for analyzing and presenting in a graphical manner single instruction, multiple data (SIMD) instructions involves disassembling a stream of machine instructions into a stream of assembly language instructions. Instruction objects “M” and “N” are created to represent SIMD instructions “M” and “N” from the stream of instructions. Instruction objects “M” and “N” include multiple data objects corresponding to the multiple data items of the respective SIMD instruction. Different colors are assigned to at least two of the multiple data objects of instruction object “M.” If a data item of SIMD instruction “N” is based on a data item of SIMD instruction “M,” the color from the source object is automatically assigned to the target object. Dependencies between data items of instruction “M” and “N” are annotated by arrows between corresponding data objects. Other embodiments are described and claimed.
