Gaming machine

Abstract

The present invention provides a gaming machine that can effectively save the storage capacity used in a specific program storage area of ​​the main ROM. [Solution] The arithmetic circuit of the gaming machine calls a specific subroutine by executing a specific call instruction used when calling a specific subroutine, and then returns to the program in the first storage means by executing a specific return instruction. The instruction capacity stored in the first storage means differs depending on whether the specific subroutine to be called calls a program stored before a specific address in the second storage means or a program stored at an address after the specific address. When the program body of the specific subroutine is stored at an address after the specific address, in order to reduce the instruction capacity, the specific call instruction calls a program stored at an address before the specific address.

Claims

1. A gaming machine that controls the progress of a game by implementing a microprocessor including an arithmetic circuit, read memory, and read / write memory, The read memory comprises a first storage means that stores programs and data directly involved in the progress of the game, and a second storage means that stores programs and data not directly involved in the progress of the game. The program stored in the second storage means contains a specific subroutine that, after being called by the program stored in the first storage means and executing processing, always returns to the program in the first storage means that called it. The arithmetic circuit executes a specific call instruction used when calling the specific subroutine to call the specific subroutine, and executes a specific return instruction to return to the program in the first storage means. The amount of instruction capacity stored in the first storage means differs depending on whether the specific call instruction calls a program stored before a specific address in the second storage means or a program stored at an address after the specific address. The instruction capacity required is greater when calling a program stored at an address after the specified address than when calling a program stored at an address before the specified address. If the program body of the specified subroutine is stored at an address after the specified address, in order to reduce the instruction capacity, the specified call instruction calls a program stored at an address before the specified address. The interrupt control state can be set to an interrupt-disabled state by executing an interrupt-disable command that can set an interrupt-disabled state, and to an interrupt-enabled state by executing an interrupt-enabled command that can set an interrupt-enabled state. Executing the aforementioned specific call command makes it possible to store a predetermined value indicating the interrupt control state when executing the interrupt disable command, and after executing the interrupt disable command and executing the aforementioned specific return command makes it possible to restore the predetermined value to its original state. A gaming machine characterized by the following features.

2. The aforementioned specific subroutine is a consistency generation process that generates consistency values ​​from a defined address range of the first storage means and the second storage means. The gaming machine described in feature 1.

3. The aforementioned specific subroutine is an initialization process for initializing the set range of the second storage means. The gaming machine described in feature 1.
