A circuit arrangement and method support offset based register address indexing, wherein register addresses to be used by an instruction are calculated using offsets to the full target register address, and the offsets are contained in the instruction and occupy less instruction space than the full address widths. An instruction may include at least one offset value that identifies a register address. During decoding of the instruction, an offset and a full target address are retrieved from the instruction, and then a register address is calculated by addition of the offset to the full target address. |
