Method in a gaming machine for providing data recovery
View Patent ↗Disclosed is a gaming machine capable of data restoration.
1. In a gaming machine comprising a processor, a first memory operatively coupled to the processor and equally divided into two memory banks, and a second memory coupled to the processor, a method for providing data recovery, comprising:
storing gaming data in the first memory;
storing a variable in each bank that identifies the integrity of gaming data stored in the memory bank; and
executing a recovery algorithm in the processor upon the variable indicating that data corruption has occurred for providing recovery of gaming data in the first memory.
2. The method of claim 1 further comprising storing gaming data comprising storing meter data.
3. The method of claim 1 further comprising storing gaming data comprising storing a data log.
4. The method of claim 1 further comprising implementing the first memory with battery backup.
5. The method of claim 1 , further comprising implementing the first memory with EEPROM.
6. The method of claim 1 , further comprising providing the first memory as a disk drive.
7. The method of claim 1 , wherein the step of storing a variable in each bank that identifies the integrity of gaming data stored in the memory bank comprises storing one of a checksum and a cyclical redundancy check.
8. The method of claim 1 , wherein executing the recovery algorithm recovers the gaming data in the first memory by replacing the corrupted data with a copy of the same data known to be good.
9. In a gaming machine comprising a processor, a set of peripherals operatively coupled to the processor by an input-output board, a first memory operatively coupled to the processor, a second memory separate from the first memory and operatively coupled to the processor, a third memory separate from the first and second memories and operatively coupled to the processor the third memory equally divided into two memory banks, a method comprising:
storing in the first memory operating software run by the processor to control the set of peripherals, the operating software comprising a non-gaming operating system and gaming-machine specific software, wherein the logic to control the peripherals is primarily implemented by the gaming-machine specific software;
storing in the second memory software run by the processor specific to a game playable on the gaming machine;
storing gaming data in each memory bank of the third memory;
storing a variable in each memory bank of the third memory that indicates the integrity of gaming data stored in each memory bank; and
executing a recovery algorithm in the processor by the gaming-machine specific software configured to recover gaming data in the third memory upon the variable indicating that data corruption has occurred.
10. The method of claim 9 wherein storing gaming data comprises storing meter data.
11. The method of claim 9 wherein storing gaming data comprises storing a data log.
12. The method of claim 9 further comprising implementing the third memory device with battery-backed memory.
13. The method of claim 9 , further comprising implementing the third memory with EEPROM.
14. The method of claim 9 , further comprising implementing the third memory with a disk drive.
15. The method of claim 9 , wherein storing the variable in each memory bank of the third memory comprises storing one of a checksum and a cyclical redundancy check.
16. The method of claim 9 , wherein the recovery algorithm comprises replacing the corrupted data with a copy of the same data known to be good.
17. The method of claim 9 wherein storing operating software in the first memory comprises implementing the non-gaming operating system with a UNIX-based operating system.
