ABSTRACT:
Information error recovery apparatus and methods are disclosed. Responsive to an error detected in information retrieved from an information store for use by a processor in a software execution flow, the software execution flow of the processor is suspended. Use of the information store by the processor is also disabled. The software execution flow of the processor is allowed to resume using information from a further information store in which the retrieved information is also stored. This allows recovery from errors without resetting the processor. The information store may be reloaded from the further information store and re-enabled for use by the processor. The information store and the further information store are a cache and a main memory, respectively, in one embodiment.
