Abstract
A master device communicating a first range of speeds at which the master device is operable, to a first slave device, the master device and the first slave device determining a second range of speeds most closely matched to the first range of speeds at which each of the master device and the first slave device is respectively operable; and the master device setting the operating range of speeds of each of the master device and the first slave device to the second target range of speeds.
Claims22
A method comprising:
- a master device communicating a first range of speeds at which the master device is operable, to a first slave device;
- the master device and the first slave device determining a second range of speeds, most closely matched to the first range of speeds, at which each of the master device and the first slave device is respectively operable;
- and
- the master device setting the operating range of speeds of each of the master device and the first slave device to the second range of speeds.

An apparatus comprising:
- a master device coupled in communication with a first slave device to provide a first range of speeds to the first slave device and to determine with the first slave device a second range of speeds at which each of the master and the first slave devices is operable.
In a multi-processor system, a method comprising:
- a bootstrap processor starting a first application processor;
- the bootstrap processor communicating to the first application processor a first pair of operating frequencies, at which the bootstrap processor is operable;
- the bootstrap processor and the first application processor determining a second pair of operating frequencies, most closely matched to the first pair of operating frequencies, at which both processors are operable;
- the bootstrap processor starting a second application processor;
- the bootstrap processor communicating to the second application processor the second pair of operating frequencies;
- the bootstrap processor and the second application processor determining a third pair of operating frequencies, most closely matched to the second pair of operating frequencies, at which the bootstrap processor and both application processors are operable;
- and
- the bootstrap processor setting each processor in the system to operate at the third pair of operating frequencies;
