Microprocessor with automatic name generation including performance indication

A microprocessor chip, comprising;

• circuitry for measuring a core clock frequency for the microprocessor;
• and
• circuitry for determining a performance indication for the microprocessor in response to the measured core clock frequency;
• wherein:
• said circuitry for measuring a core clock frequency comprises,
• a first counter circuit that counts cycles of a reference clock for the microprocessor, and
• a second counter circuit that counts cycles of a core clock in the microprocessor;
• said circuitry for determining a performance indication comprises a lookup table coupled to an output of the second counter circuit;
• and
• said lookup table stores a set of predetermined performance indicators for the microprocessor such that the core clock frequency selects one of the predetermined performance indicators.

A method of determining performance of a microprocessor, comprising the steps of:

• producing a core clock signal that synchronizes execution of instructions in a processor core of said microprocessor;
• producing a core clock frequency indication that specifies a frequency of said core clock signal;
• and
• converting said core clock frequency indication into a performance number (Pnumber) and provide said Pnumber to said processor core.
