| 20110058629 | COEFFICIENT PROVISION SYSTEM AND METHOD USING SQUARE MATRICES - Methods and systems for providing coefficients to data processing systems. The method operates by calculating the coefficients instead of storing them. A full rank square matrix (having either 1 or −1 in all positions) is used in conjunction with a single column matrix of specific numbers. Depending on the binary input, one row in the square matrix is matrix multiplied with the single column matrix to arrive at the desired coefficient. The result of the matrix multiplication is the desired coefficient after a series of additions and subtractions between the specific numbers in the single column matrix. An implementation of the method has an input module which receives the digital input, a square matrix module that selects a 1 or a −1 to be applied to specific stored values, a stored values module which stores the stored values and which multiplies the selected 1 or −1 to the relevant stored value. Finally, an accumulator module adds and subtracts the stored values after the relevant 1 or −1 has been applied. The output of the accumulator module is the desired coefficient. | 03-10-2011 |
| 20110043256 | SAMPLING FILTER USING MULTIPLE CLOCKS - Methods and devices for forming a series of samples of a filtered version of an input signal. Multiple tap current cells each generate a tap current from the signal. Multiple distribution means couple the tap current cells with multiple integrating means. The distribution means is controlled by a first clock signal. The multiple integrating means integrate tap currents that they receive and these integrating means form the samples. The tap currents generated are each sent to each integrating means in a predetermined sequence according to the first clock signal. The integrating means each use integrating and sampling phases controlled by a second clock signal. During the integrating phase an integrating means receives tap currents in sequence, while during the rest phase, no tap currents are received and the contents of the circuit are sampled and the integrator means is reset. | 02-24-2011 |
