The VLIW (Very Long Instruction Word) architecture is rooted in the parallel microcode used yet at the dawn of computer engineering and in Control Data CDC6600 and IBM 360/91 supercomputers. In 1970 most computation systems were equipped with additional vector signal processors using VLIW-like long instructions flashed in ROM. These processors were used for(More)
