PCIE clock rate stepping for graphics and platform processors

摘要: Circuits, methods, and apparatus for modifying the data rate of a bus. In circuit having two processors coupled by bus, each learn that other is capable operating at modified rate. The then changed to Each processor may other's capability reading vendor identification, example from defined message stored on processor. Alternately, provide an instruction operate rate, writing processor's extended registers. another communicating over it determined both are transmitting receiving An provided one or transmit
