Abstract
A data processing system having multiple register contexts is described. One embodiment of the present invention uses a user programmable context control register for each of the multiple register contexts to allow for the mapping of portions of an alternate register context into a current register context. The context control register may also be used to provide for the sharing of common stack pointers among multiple register contexts. Therefore, when operating in a current register context, the context control register may be used to access portions of an alternate register context in place of accessing corresponding portions of the current register context.
