Method and apparatus for determining processor performance

An apparatus for determining performance of a processor when processing a unit of data, the apparatus comprising:

• a receiving device operable to receive, at a first sample rate, data indicating the performance of the processor when processing the unit of data;
• a generating device operable to generate an identifier that identifies the unit of data being processed;
• a comparing device operable to compare the identifier with previous identifiers at a second sample rate;
• and
• an outputting device operable to output the identifier of the unit of data being processed and the performance data when, during the comparing step, a predetermined condition is met.

A computer device comprising:

• a display driver operable to control a display;
• a central processing unit operable to control the display driver;
• a graphics processor coupled to both the display driver and the central processing unit;
• and
• an apparatus for determining performance of a processor when processing a unit of data, the apparatus comprising:
• a receiving device operable to receive, at a first sample rate, data indicating the performance of the processor when processing the unit of data;
• a generating device operable to generate an identifier that identifies the unit of data being processed;
• a comparing device operable to compare the identifier with previous identifiers at a second sample rate;
• and
• an outputting device operable to output the identifier of the unit of data being processed and the performance data when, during the comparing step, a predetermined condition is met.

A non-transitory computer readable storage medium storing a computer program therein, the computer program, when executed by a processor, causes the processor to perform a method of:

• receiving, at a first sample rate, data indicating the performance of the processor when processing the unit of data;
• generating, with a processor, an identifier that identifies the unit of data being processed;
• comparing the identifier with previous identifiers at a second sample rate;
• and
• outputting the identifier of the unit of data being processed and the performance data when, during the comparing step, a predetermined condition is met.
