PURPOSE:To easily measure a load factor by utilizing the timer function and processing capability that a CPU itself has. CONSTITUTION:The CPU1 processes a specific application program with information received from an input/output device 3 and supplies the result to the input/output device 3 again. A memory 2 and a display device 4 are connected to the CPU1. This CPU1 measures the frequency of looping of an instruction waiting program within a specific time and calculates the CPU load rate on the basis of said frequency of looping of the instruction waiting program in the absence of an input instruction within the specific time. This calculated CPU load factor is displayed on the display device 4. |
