Abstract

PURPOSE:To detect the runaway of software by hardware by deciding whether or not a value incremented for each execution of the instruction and reset by the software reaches a prescribed value in the operand memory. CONSTITUTION:An environment identifier stored in an input packet register 21 is used as an address via an address register 23 in an operand memory at the start of instruction and data corresponding to the address is read from a counter memory 24 and written again in the memory 24. On the other hand, when a counter memory part corresponding to the environment identifier or the instruction code is a reset instruction, an operand memory control circuit 22 resets the data register 28 before reaching the overflow value to set an initial value to the counter memory. However, when the value reaches the overflow value, it is informed to the circuit 22, then the circuit 22 recognizes the occurrence of runaway of the software.
