摘要： A computer implemented method, bus switching system, and computer usable program code are provided for saving bus switching power and reducing noise. A request for data is received from a requester by a first cache. A determination is made as to whether the data is stored on the first cache. Responsive to determining that the data is stored on the first cache, a bus in a plurality of buses is identified on which to return the data forming an identified bus. The data is sent to the requester on the identified bus. A logical state is initiated on the remaining plurality of buses stemming from the first cache in order to save bus switching power and reducing noise.

摘要： An incrementor circuit and method for incrementing is provided that computes an output data word by increasing an input data word magnitude by one of several integer values. The incrementor circuit includes a mode increment signal circuit providing a designation of one of the integer values for increasing the input data word magnitude. A single constant incrementor is connected to the mode increment signal circuit and the input data word and provides an intermediate sum by selectively adding a constant to the input data word. A multiplex circuit logically combines selected input data word bit position values with the mode increment signal circuit designation forming logical bit position values and directs selected input data word bit position values, selected logical bit position values, and selected bit position values of the intermediate sum to form the output data word.

摘要： A circuit and a method for regulating a voltage supply where the method includes the steps of concurrently measuring temperature, IR drop and frequency response within the circuit, adjusting voltage supplied to the circuit in response to the measured temperature, IR drop and frequency response, and determining a correction value based on the variance of the measured frequency response from an expected frequency response and providing a correction for subsequent predetermined frequency response values. The frequency response measurement is dependent upon the constant bandgap voltage source which may very according to temperature. Upon a determination that corrections may be required for the bandgap voltage source to compensate for temperature variations, the measurement process which uses the bandgap voltage source can be altered to compensate for the temperature variations.

摘要： A circuit and method are provided for storing a data word in a latch and determining the number of consecutive equal value bits within the data word. The data word consists of bits stored in unique bit positions and having a least significant bit position and a most significant bit position. The data word is examined to determine the number of consecutive bits having the same numeric value. The invention first corrects for any single bit anomaly within the consecutive equal value sequence, counts the number of consecutive bits having this equal value using logic that examines only every other bit position of the stored data word and provides a numeric value representing this number of consecutive equal value bits.
