摘要： A method of finding an unknown value from within a range of values is disclosed that divides the range into weighted subranges and then, beginning with an arbitrary search value within the range, performs a number of simple comparisons to determine the value for each subrange that will result in a match with the target value. This method can also detect those cases where the target value lies outside the range. In one embodiment, the method of finding an unknown value within a range of values is applied to impedance matching. In this embodiment, the output impedance of a pin on an integrated circuit is automatically matched to the impedance of the load connected to it. The output driver has a controllable impedance that can be adjusted within a specific range of impedances to match the external load impedance it is to drive.

摘要： Systems, data paths and methods of transferring data. By utilizing the systems, data paths, and methods, data can be transferred at a single or double rate. One embodiment of the present invention provides a system having a data unit, an output register, and a holding register. The output register is coupled to the data unit. The holding register is coupled to the data unit and the output register. Data from the data unit is passed to the output register and the holding register substantially simultaneously and data from the holding register is then passed to the output register. Data can be output from the output register.
