Abstract
A method and apparatus for operating a computer system comprising a first and a second computing unit, the method comprising selecting a first clock frequency for operation of said first computing unit, and selecting a second clock frequency for operation of said second computing unit wherein said first and said second frequencies differ one from the other by at least a predetermined bandwidth.
Claims17
A method for operating a computer system comprising a first and a second computing unit, the method comprising selecting a first clock frequency for operation of said first computing unit, wherein said first frequency is a function of a first predetermined number allocated to said first computing unit, and selecting a second clock frequency for operation of said second computing unit, wherein said second clock frequency is different from said first clock frequency, wherein said second frequency is a function of a second predetermined number allocated to said second computing unit, wherein said first and said second clock frequency are each dynamically allocated to a respective computing unit on start-up or resetting of the system, and wherein said first and said second frequencies differ one from the other by at least a predetermined bandwidth.
A method for operating a computer system comprising a plurality of computing units, the method comprising, selecting a plurality of different clock frequencies;
- allocating a different one of each of said plurality of clock frequencies to each of said plurality of computing units, wherein said allocating includes allocating a predetermined number to each computing unit and setting each unit clock frequency as a function of said number, wherein each different frequency is dynamically allocated to a respective computing unit on start-up or resetting of the system, and wherein each of said plurality of frequencies differs from at least one other of said frequencies by a predetermined bandwidth.
An apparatus for start-up of a computer system comprising a plurality of computing units, the apparatus comprising means for setting a different clock frequency for each unit so that said units each operate at a different frequency, each frequency differing from another frequency by at least a predetermined minimum bandwidth, means for dynamically allocating a different frequency to a respective computing unit on start-up or resetting of the system, and means for determining said predetermined minimum bandwidth as a multiple of a predetermined base frequency.
