1. Apparatus for processing data, said apparatus comprising:

  • a processor operable to perform data processing operations under control of program instructions, said processor being operable under program instruction control to generate a performance level request signal indicative of a desired data processing performance level of said processor; and

    a mapping circuit operable to map said performance level request signal into a control signal supplied to one or more further circuits to control operation of said one or more further circuits so as to support said desired data processing performance level of said processor such that said program instructions controlling generation of said performance level request signal are independent of how said one or more further circuits are controlled to meet said desired data processing performance level, wherein said mapping circuit performs at least one many to one mapping between performance level request signal values and corresponding control signal values.
