ABSTRACT:
A data processing system selects between a general register file and an alternate register file during an operation such that resources of the data processor may be more flexibly mapped to a context of the data processing system and, therefore, be more efficiently utilized. A control bit in a processor status register (PSR) is used to select between a general register file and an alternate register file depending upon a logic value to which it is set to a during an exception handling process.
