Abstract
A central processing unit in a microprocessor, or the like, executes at high speed a simple program and sets a different immediate depending on a true or false state of a predetermined condition. In the central processing unit, the first and second immediates are set in the instruction code, which is prefetched by an instruction queue. Depending on whether a value of one or zero is stored in the zeroflag, which corresponds to the true or false state of the predetermined condition, the first or second immediate is written into an address location of the register or the memory designated by the same instruction code.
