專利摘要 |
A segmental allocation method of expanding RISC processor register includes the steps of a) setting an instruction format of the RISC processor, the destination register field being set having 6 bits to correspond to 64 registers and at least one source register field having at least 4 bits to correspond to at least 16 registers; b) providing two solutions to the problem resulting from that the instruction format in the step a) goes beyond range under some circumstances; and c) setting a register segment allocation algorithm having the steps of c1) providing and grouping a plurality of pseudo registers; c2) prioritizing the pseudo registers in each of the groups; c3) combining the groups pursuant to the priorities thereof; and c4) locating the physical register of lowest computational cost. |
