Gerät und Verfahren um von der Topografie abhängig zu signalisieren |
摘要 |
Bus communications are optimized by adjusting signal characteristics in accordance with one or more topography dependent parameters. In a bus transmitter a transmit signal characteristic is adjusted in accordance with a topography dependent parameter. A port in the bus transmitter receives the topograpy dependent parameter for later use by the parameter adjustment circuitry. The parameter adjustment circuitry adjusts a parameter control signal in accordance with the topography dependent parameter, which is coupled to the out-put driver. Prior to driving an output signal onto a bus, the output driver adjusts the transmit signal characteristics in accordance with the parameter control signal. In a bus receiver, a receive signal characteristic is also adjusted in accordance with a topography dependent parameter. A port associated with the bus receiver receives the topography dependent parameter and stores it in a register. Parameter adjustment circuitry adjusts a control signal in accordance with the stored topography dependent parameter. An input buffer receives an input signal from a bus coupling the receiver to a transmitter of the input signal. The input buffer generates a first signal from the input signal by adjusting a parameter of the input signal in accordance with the control signal. |
