ABSTRACT:
A microprogram branching method and apparatus generate a continue address by successively incrementing an address, generate a branch address by referring to a branch address table depending on predetermined branch conditions, where the branch address table prestores branch addresses, discriminate whether or not a branch is to be made depending on the predetermined branch conditions and obtaining a discrimination result, select the continue address normally and selecting the branch address when the discrimination result indicates that the branch is to be made, and output a data which is read out from an address of a main memory depending on the selected address, where the main memory prestores microprograms.
