Abstract
A scheme for improving the decoding time of macroinstruction opcodes in a programmed computer is provided. By having a direct Instruction Jump Table responding to macroinstructions and a pipelined Address Jump Table responding to the same macroinstructions simultaneously, larger sequences of microinstructions are decoded in a minimum number of microcycles, thus resulting in a faster operating programmed computer.
