Method for measuring quantity of usage of CPU

A method for measuring processing resource utilization in a personal computer, comprising:

• providing a personal computer executable process algorithm for monitoring the usage of a processor;
• reading execution times of threads during a predetermined timer time interval using one or more manager functions, wherein the threads are executed by the processor;
• adding execution time values for each thread that is not a system thread to get a first total;
• and
• determining a quantity of usage of the processor using the first total, wherein the quantity of usage is used by the personal computer.

A method for measuring CPU usage, the CPU executing threads, comprising:

• reading the execution times of all threads except for a system thread during a prescribed timer time interval;
• adding the values of the execution times to obtain a first sum;
• subtracting a second sum of previously executed and stored thread execution times from the first sum to obtain a result;
• and
• calculating a CPU usage by dividing the result by the prescribed timer time interval, wherein the CPU usage is stored in a memory.

A method for updating a resource utilization value in an updatable usage value register contained in a processing resource circuit, comprising:

• reading execution times of a first subset of threads executing during a time interval, the first subset excluding system threads;
• adding the read execution times of the first subset of threads to obtain a first total;
• calculating a current resource utilization information based on a calculation involving the first total and the time interval;
• and
• updating the updatable usage value register with the current resource utilization information.

An article including a machine-readable storage medium containing instructions, said instructions, when executed, cause a personal computer to:

• provide an operating system registry containing a processor usage information of a processor;
• read execution times of threads during a predetermined timer time interval using one or more manager functions when the threads are executed by the processor;
• add execution time values for each thread that is not a system thread to get a first total;
• determine a quantity of usage of the processor using the first total;
• and
• update the processor usage information in the operating system registry.
