Extending a register file utilizing stack and queue techniques

A processor integrated circuit operable to:

• in response to a first instruction, store a first value in a register in a set of registers, the set of registers each individually addressable by register operations executable on the processor using a corresponding register identification;
• and
• in response to a second instruction, store a second value in the register;
• wherein the register has multiple storage locations and wherein values stored in the multiple storage locations of the register are accessed according to the order in which the values have been stored.

A code preparation tool encoded as software executable code configured to:

• store a first value in a register in a set of registers, the set of registers each individually addressable by register operations executable on the processor using a corresponding register identification;
• and
• store a second value in the register;
• wherein the register has multiple storage locations and wherein values stored in the multiple storage locations of the register are accessed according to the order in which the values have been stored.

Software encoded in one or more computer readable media, the software comprising:

• a sequence of instructions executable on a processor, the sequence including one or more executable instructions that address a particular register of the processor and operate on a value stored therein,
• wherein at least one of the executable instructions directs the processor to store a first value in a register in a set of registers, the set of registers each individually addressable by register operations executable on the processor using a corresponding register identification;
• and
• at least another one of the executable instructions directs the processor store a second value in the register;
• wherein the register has multiple storage locations and wherein values stored in the multiple storage locations of the register are accessed according to the order in which the values have been stored.
