Abstract
A processor architecture scheme which allows for encoding of multiple addressing modes through use of virtual register addresses in order to maximize number of directly addressable registers in the processor architecture scheme. A set of virtual address register locations associated with an indirect addressing pointer is reserved in memory. The number of virtual register address locations reserved is equal to a number of indirect addressing modes associated with the indirect addressing pointer. Each of the virtual register address locations initiates an indirect addressing mode to be used with the associated indirect addressing pointer when accessed.
