Fault tolerant gaming systems
View Patent ↗Method and apparatus are provided wherein, in one example embodiment, a gaming machine includes a computing platform and a software program executing on the computing platform to provide a gaming experience to a user of the gaming machine, and there are provided one or more hardware or software components operative on the computing platform to detect faults occurring on the platform. At least one fault recovery software component is also operative on the gaming platform, and the fault recovery software component is adapted to operate in response to the detection of a fault.
1. A gaming system comprising:
a computing platform including one or more processors;
a software program executing on a primary board of the computing platform to provide a gaming experience to a user of the gaming system;
one or more fault detection components operative on the computing platform to detect faults occurring on the platform, the one or more fault detection components comprising at least one of a hardware component or a software component; and
at least one fault recovery software component operative to execute on a secondary board of the computing platform;
wherein the computing platform, in the absence of a detected fault, receives a request to execute a calculation on a received data set and, in response to results of the calculation meeting certain criteria, the one or more fault detection components causes the at least one fault recovery software component to execute on the secondary board of the computing platform.
2. The gaming system of claim 1 , wherein the results meeting certain criteria indicates a hardware fault.
3. The gaming system of claim 1 , wherein the results meeting certain criteria indicates a fault on the primary board of the gaming machine.
4. The gaming system of claim 1 , wherein the at least one fault recovery software component causes the gaming system to save one or more states of the gaming system and then restart the gaming system to an error-free condition.
5. The gaming system of claim 4 , wherein the one or more states represent at least one probable stable configuration, and wherein the one or more states are stored in a nonvolatile storage device.
6. The gaming system of claim 4 , wherein restarting the gaming system to an error-free condition includes restoring the last known stable configuration stored in a memory device.
7. The gaming system of claim 1 , wherein the at least one fault recovery software component, when executed, causes the computing platform to halt or restrict operation of the gaming system.
8. The gaming system of claim 1 , wherein the request and the received data are received from a server connected to a network.
9. The gaming system of claim 1 , wherein the request and the received data are received from a server connected to a network, and the results of the calculation are transmitted to a server connected to a network for comparing to the certain criteria.
10. A method of operating a gaming system to conduct a wagering game, the gaming system including a computing platform with a primary board and a secondary board, and one or more fault detection components operative on the computer platform to detect faults occurring on the computing platform, the method comprising:
executing a software program on the primary board to present the wagering game to a user;
receiving, at the computing platform and in the absence of a detected fault, an electronic request to execute a calculation on a received data set;
in response to results of the calculation meeting certain criteria, the one or more fault detection components causing a fault recovery software component to execute on the secondary board.
11. The method of claim 10 , wherein, in response to the results of the calculation meeting certain criteria, the method further comprises initializing a boot procedure and increasing the speed of the boot procedure by causing the computing platform to load during the boot procedure only those graphics or sound files that are required to initiate play of the wagering game.
12. The method of claim 10 , wherein executing the fault recovery software component causes the gaming system to initialize a boot procedure, causes the computing platform to verify the authenticity of only those files that are required to initiate play of the wagering game, causes the computer platform to initiate the play of the game, and causes the computer platform to verify the authenticity of additional files after the play of the game has been initiated.
13. The method of claim 10 , wherein the results of the calculation meeting certain criteria indicates a fault on the primary board of the gaming system.
14. The method of claim 10 , further comprising continuously receiving the request to execute the calculation and repeatedly determining if the results of the calculation meet the certain criteria.
15. A gaming machine configured to play a wagering game, the gaming machine comprising:
a computing platform including one or more processors, a primary board, and a secondary board;
a software program operative to execute on the primary board to provide the wagering game to a user;
one or more fault detection components operative on the computing platform to detect faults occurring on the computing platform, the one or more fault detection components comprising at least one of a hardware component or a software component; and
at least one fault recovery software component operative to execute on the secondary board;
wherein the computing platform, in the absence of a detected fault, receives a request to:
execute a calculation on a received data set, and
in response to results of the calculation meeting certain criteria, causes, via the one or more fault detection components, the at least one fault recovery software component to execute on the secondary board.
16. The gaming machine of claim 15 , wherein executing the at least one fault recovery software component includes saving a state of the gaming machine and restarting the gaming machine in an error-free condition.
17. The gaming machine of claim 16 , wherein a state of the gaming machine in the error-free condition is different from the saved state of the gaming machine.
18. The gaming machine of claim 15 , wherein the request and the received data set are received from a server connected to a network.
19. The gaming machine of claim 15 , wherein the computing platform further causes the results of the calculation to be transmitted to a server connected to a network for comparing to the certain criteria.
20. The gaming machine of claim 15 , wherein, the at least one fault recovery software component includes a self-diagnostic check.
21. The gaming machine of claim 15 , wherein the results meeting the certain criteria indicates a fault on the primary board of the gaming machine.
