Abstract
A gaming machine may include memory, a software program loaded into the memory and a trusted cache. The trusted cache may include a context data save engine, a context data recovery engine and a restart engine. The context data save engine may be configured to save the context and state of the gaming machine at least upon sensing a failure condition. The context data recovery engine may be configured to load the context and state from the context data save engine back into memory, and the restart engine may be configured to restart the gaming machine and restore execution of the software program, and may be further configured to carry out a multi-stage recovery process that may include a soft reboot, a hardware reset and a power-off and, after a predetermined delay, a power-on of the gaming machine, attempting to restart the software program between each stage of the process.
