  • Processor and data processing method with non-hierarchical computer security enhancements for context states
    Patent number: 8850557
    Abstract: Disclosed are a processor and processing method that provide non-hierarchical computer security enhancements for context states. The processor can comprise a context control unit that uses context identifier tags associated with corresponding contexts to control access by the contexts to context information (i.e., context states) contained in the processor's non-stackable and/or stackable registers. For example, in response to an access request, the context control unit can grant a specific context access to a register only when that register is tagged with a specific context identifier tag. If the register is tagged with another context identifier tag, the contents of the specific register are saved in a context save area of memory and the previous context states of the specific context are restored to the specific register before access can be granted.
