  • Microcode generation for a scalable compound instruction set machine
    Patent number: 5398321
    Abstract: An apparatus for generating microcode in a scalable compound instruction set machine operates in response to compounding information indicating that two or more adjacent instructions are to be executed in parallel. Separate and independent microcode is held in control store for each possible instruction in a group. Microcode sequences for each instruction of a group of instructions to be executed in parallel are merged in response to the compounding information into a single microinstruction sequence.
