On the other hand, the performance of the entire computer including the peripheral circuit whose input / output is controlled by this CPU is "MIP
It is represented by an index called “S” or “MFLOPS”. "MIPS" means Million Istruction Per Sec
It is an abbreviation for ond, and is a unit indicating how many millions of operations can be performed per second. Also, "MFLOPS" means Mi
llion Floating-point Operation Per Second, which is a unit indicating how many millions of floating-point operations can be performed per second.

Therefore, in order to grasp the CPU load factor of the computer during the arithmetic processing in real time, what percentage of the maximum load represented by the above-mentioned "MIPS" or "MFLOPS" is operating? Just show it. CP on the operating system (OS) side
When a check command for checking the current load factor of U is provided, the load factor of the CPU can be grasped by inputting the check command.

However, when the operating system (OS) side does not have the above-mentioned inspection command, a program for measuring the load factor is created and the program is interrupted during the arithmetic processing. However, if the program is interrupted during arithmetic processing, other processing temporarily enters the halt state.
There is a problem that the load factor cannot be accurate, and the result of processing is displayed on the display device side, so that the load factor cannot be displayed in real time. In addition, in order to obtain the CPU load factor based on the inspection command, a command input operation must be performed each time, and in order to grasp the load factor in real time, the command must be continuously input. Not relevant. Therefore,
The present invention has been made in view of the above-mentioned circumstances, and CP
An object of the present invention is to provide a load factor display device capable of continuously displaying the load factor of U in real time.

A first load factor detection means for generating a first load factor signal according to the above, and a second load factor signal for detecting the number of calculations executed by the calculation unit and generating a second load ratio signal according to the number of calculations. And a third load factor detection unit that detects an address space managed by the storage unit and generates a third load factor signal that represents a ratio of the address space to the entire address space. Of the first to third load factor signals Zureka or they first to third,
And a load factor display means for displaying the load factor of the central processing unit by combining the load factor signals of 1.

[0007]

In the present invention, the first load factor detection means generates the first load factor signal according to the number of instruction times, and the second load factor detector means the second load factor signal according to the number of calculations. And the third load factor detection means generates a third load factor signal representing the ratio of the address space to the entire address space. Then, the load factor display means displays any one of the first to third load factor signals or the load factor of the central processing unit by combining these first to third load factor signals.
Therefore, the load factor of the central processing unit can be continuously displayed in real time without interfering with the processing operation of the central processing unit.
