ABSTRACT:
A method for conserving processor registers during the execution of a program in which short term data having a short processing period and long term data having a long processing period are processed. The method includes the acts of: providing a program having a first address space for addressing the short term data and a second address space for addressing the long term data, defining within the processor a first plurality of pooled registers for storing the short term data, executing said program, allocating, responsive to the program, at least one of the pooled registers to the first address space, controlling, via said program, the allocated pool register for the duration of said short processing period, and terminating program control of the allocated pool register upon the expiration of said short processing period.
