ADDRESS GENERATION CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide an address generation circuit reducing a circuit scale. SOLUTION: A fetch address generation circuit 20 formed of adders 21 and 22 generates a fetch address based on an execution address generated by a program counter circuit 110 formed of a flip flop 111, an adder 112 and a multiplexer 113 and on a differential address generated by a differential address generation circuit 10 formed of a flip flop 11 and a computing element 12.
