Title:
PACHINKO MACHINE
Document Type and Number:
Japanese Patent JP3225228
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve more complicate and more processing by a method wherein two central processing units are arranged on one chip to form a controller and are both made up of a dual one-chip microcomputer which are operated alternately at very short intervals to perform a parallel operation.
SOLUTION: A dual one-chip microcomputer 1 has two central processing units(CPU) and is sustained to allow accessing of an internal ROM and an external RAM from the both while letting an external ROM 3 and an external RAM 5 be accessed from both the CPUs. The first CPU is used for main processing to control the proceeding of a game, for instance and the second CPU is used for sub processing to control a sound generator, a light emitting device and other output devices. Both the CPUs can use the memories exclusively or in common to enable storing of an own program and common management of common data thereby simplifying the complicated processing of games.
