Abstract: A scheduling apparatus for dynamically setting a size of a rotating register of a local register file during runtime ids provided. The scheduling apparatus may include a determiner configured to determine whether a non-rotating register of a central register file is sufficient to schedule a program loop; a selector configured to select at least one local register file to which a needed non-rotating register is allocated in response to a determination that the non-rotating register of a central register file has a size which is sufficient to loop a program loop; a scheduler configured to schedule a non-rotating register of the at least one selected local register file.

Abstract: An apparatus and method for calculating a physical address of a register in a processor are provided. The apparatus includes an offset calculator configured to calculate an offset between the physical address and a logical address of the register, based on a current iteration number and a size of a rotating register; an address calculator configured to calculate the physical address of the register by adding the calculated offset to the logical address of the register; and an address corrector configured to output a final physical address of the register based on the calculated physical address and the size of the rotating register.
