Abstract
Microprocessors use a conditional branch instruction so as to change processing in accordance with conditions. According to the prior art, a NOP instruction, which causes no operation, is used when a condition is satisfied, and the use of the NOP instruction inevitably lengthens the processing time. According to the present invention, a conditional transfer instruction is included in the instruction set of a microprocessor, and a flag decoder is additionally employed. The flag decoder determines whether a condition is satisfied or not, and outputs a control signal on the basis of the determination. The control signal is supplied to the instruction decoder of the processor to make a data transfer operation effective or ineffective. Accordingly, it is not necessary to use a NOP instruction, and the processing time can be as short as possible.
