Abstract
A parallel processor has a plurality of operation units that execute operation instructions, and a multi-bank register file in which a plurality of banks each having a plurality of registers are formed. Each of machine instructions, which are input simultaneously, is split into a plurality of nano-instructions each of which includes at least one of an access instruction and operation instruction. The output clock cycles of operation instructions with respect to the operation units are arbitrated. Furthermore, the output clock cycles of access instructions to the multi-bank register file are arbitrated so as to prevent access instructions from contending in an identical bank in the multi-bank register file.
