Abstract
PURPOSE:To perform the tracing operation without causing the overhead by carrying out the tracing operation to a desired instruction code in parallel with execution of an instruction of a processor. CONSTITUTION:A single instruction code includes two independent instructions and an instruction executing part 2 and an action analyzing part 3 work in parallel with each other to carry out both instructions within an instruction cycle. Therefore the tracing operation is carried out in parallel with execution of the instruction of a 1st field FF as long as an instruction for the tracing operation is set in a 2nd field SF of a desired instruction code. In such a way, the original program processing is not affected by the tracing operation and the occurrence of the overhead is avoided.
