Abstract
An apparatus for increasing addressability of registers within a processor is disclosed. The apparatus includes a set of apparent registers and a set of real registers. The total number of real registers is substantially higher than the total number of apparent registers such that only a subset of the real registers is referenced by all of the apparent registers at any given time. Any one of the real registers can be designated by an instruction via one of the apparent registers. Any one of the actual registers can also be directly designated by an instruction.
Claims13
An apparatus for increasing addressability of registers within a processor, said apparatus comprising:
- a set of apparent registers;
- and
- a set of actual registers, wherein the number of said actual registers is greater than the number of said apparent registers such that only a subset of said actual registers is referenced by all of said apparent registers at any given time, wherein any one of said actual registers is capable of being designated by an instruction via at least one of said apparent registers, wherein any one of said actual registers is also capable of being directly designated by an instruction.
A method for increasing addressability of registers within a processor, said method comprising:
- providing a set of apparent registers;
- and
- providing a set of actual registers, wherein the number of said actual registers is greater than the number of said apparent registers such that only a subset of said actual registers is referenced by all of said apparent registers at any given time, wherein any one of said actual registers is capable of being designated by an instruction via at least one of said apparent registers, wherein any one of said actual registers is also capable of being directly designated by an instruction.
