PROBLEM TO BE SOLVED: To obtain data on real time during a game without using a CPU by a method wherein the use condition of a CPU for controlling a game is monitored to obtain a game program or data during the execution of the game by utilizing a bus during a period when the bus is not used. SOLUTION: The processing unit 200 for use in a game is manufactured as an IC for amuse chips and is divided into a game block 200A for performing a game control and a managing block 200B for managing information. The block 200B includes a boot ROM 212, a parameter memory 213, a bus monitor circuit 214 and a control circuit 218, etc. And the condition of a CPU bus 210 is monitored by the circuit 214, and when the bus 210 is not used by a CPU core 201, a program ROM 202 and a user work RAM 203 are accessed as required, to take in a game program or data during the execution of a game into the managing block 200B.
