Abstract

PURPOSE: To suitably detect the location of program loop occurrence.
CONSTITUTION: The unit provides the first to third registers, ADR1, ADR2 and ADR3. The first register ADR1 stores the instruction address of the cycle under execution, the second register ADR2 stores the instruction address executed at the cycle before by one, and the third register ADR3 stores the output value of ADR1 when the output value of ADR1 is smaller than that of ADR2. Further, in the cycle after the said cycle, when the output value of ADR1 is in agreement with that of ADR2, the program loop detection signal 209 is outputted to stop the execution of the program.
