MICRO PROGRAM CONTROL METHOD AND APPARATUS THEREOF HAVING BRANCH INSTRUCTIONS

In an information processing apparatus which executes micro programs having branch instructions, two micro instructions are read at once, each of which instructions comprises either a field for specifying the branch target address in the following Nth (N≧2) cycle from the reading cycle of the micro instruction, or a field for determining the termination of micro program in the following Nth (N≧2) cycle, and a control field for controlling the execution in the next cycle.
