Abstract
According to this invention, when a program requiring an inseparable operation is to be executed, prior to its program processing, an instruction fetch counter setting instruction is executed by an instruction fetch counter setting unit, and a value indicated by the instruction fetch counter setting instruction, i.e., an instruction count required for the program processing, is set in an instruction fetch counter. The instruction fetch counter is counted down by a count down unit every time an instruction is fetched. When an interrupt is generated, an interrupt control unit refers to the instruction fetch counter. When the reference value is '1' or more, the interrupt is inhibited until the value is set to be '0.'
