Very long instruction word compressing and decompressing method, involves producing secondary-very long instruction word with decompression phase, where segment of compressed instruction word is interchanged

摘要

The method involves dividing a primary-very long instruction word (VLIW) (2) into same size segments (3) during compression phase, where breadth of the segments is independent of the layout of instruction set architecture and contains a compressed instruction word of the segment. The compressed instruction word varies between the primary-VLIW and a reference-primary-VLIW. A secondary-VLIW is produced with a decompression phase, where the segment of the compressed instruction word is interchanged into a reference secondary-VLIW (7) identical to the reference-primary VLIW. An independent claim is also included for an arrangement for implementing a method for compressing and decompressing a very long instruction word.
