11. Decoupled architectures play an important role in scheduling in very long instruction word ( VLIW ) architectures. 12. The 28 / had 1024-bit instruction words . 13. One attempt to break out of this limit is the very long instruction word ( VLIW ) concept. 14. By 1995, RISC had been overtaken in design circles by an approach called VLIW, for Very Long Instruction Word . 15. This required small opcodes in order to leave room for a reasonably sized constant in a 32-bit instruction word . 16. Speculation, prediction, predication, and renaming are under control of the compiler : each instruction word includes extra bits for this. 17. If this request was accepted, I would follow the instructions word -by-word and make a bot that would make major contributions. 18. For example, on PIC16, CALL and GOTO have 11 bits of addressing, so the page size is 2048 instruction words . 19. One attempt to introduce a new ISA are the very long instruction word ( VLIW ) architectures, typified by the Itanium. 20. Each long instruction word is 64 bits wide and specifies an arithmetic operation and a branch or a load / store.
