| 20080243971 | METHOD AND APPARATUS FOR CALCULATING AN SSD AND ENCODING A VIDEO SIGNAL - The present invention relates to a method and apparatus for calculating the Sum of Squared Differences (SSD) between a source block and a reconstructed block of image or video data encoding according to an encoding scheme such as H.264/AVC. In a preferred embodiment, the method computes the SSD by finding the SSD between coefficients of an integer transformed residual block and the corresponding inverse-quantized coefficients. Preferably the inverse quantized coefficients are found with the aid of a look up table. This method may save computing time and processing power compared to calculating the SSD directly from the source and reconstructed blocks. The SSD is related to the distortion caused by encoding and the method may be used in calculating the rate-distortion of a particular encoding mode. One embodiment of the invention encodes a block of data by selecting the encoding mode with the least rate-distortion. | 10-02-2008 |
| 20110225218 | LOW-RATE SAMPLING OF PULSE STREAMS - A method includes accepting an analog input signal that includes a sequence of pulses. The analog input signal is filtered so as to produce a filter output, using a filter whose time-domain response is confined to a finite time period and whose frequency-domain response is non-zero at a finite set of integer multiples of a frequency shift Δω, and is zero at all other integer multiples of Δω. The filter output is sampled so as to produce digital samples. Respective amplitudes and time positions of the pulses in the sequence are calculated based on the digital samples. | 09-15-2011 |

| 20080201394 | Computer Technical Solution Of The Digital Engineering Method Of Hybrid Numeral Carry System And Carry Line - The present invention relates to the digital engineering method and the field of computer, and it puts forward a new digital engineering method which can remarkably increase the computation speed and greatly reduce the error rate of written calculation. The present invention uses the “method of hybrid numeral carry system and carry line”, in which K common Q-ary numerals that participate in the computation of addition and subtraction are transformed into K or 2K numerals of hybrid numeral carry system, then said K or 2K numerals are added for the sum in the hybrid numeral carry system. “Adding by place” is performed from the lowest place or at each place at the same time, and the number of the sum is written into the next computation layer; meanwhile, the obtained “hybrid numeral carry” is put into the next computation layer or at the empty place or zero place of the adjacent high place of any data line that has not undergone the computation in the present computation layer. Such computation is repeated until only one numeral is obtained after the computation in the computation layer. Then the finally obtained numeral is the sum of the addition in the hybrid numeral carry system. The present invention also provides a computer technical solution of hybrid numeral carry system and carry line. | 08-21-2008 |
| 20110131260 | EFFICIENT DETECTION ALGORITHM SYSTEM FOR A BROAD CLASS OF SIGNALS USING HIGHER-ORDER STATISTICS IN TIME AS WELL AS FREQUENCY DOMAINS - An algorithm system to detect a broad class of signals in Gaussian noise using higher-order statistics.

This algorithm system gives the time frequency detection ratio that may be used to determine if the detected signal falls in Class Single-Carrier of Class Multi-Carrier.

| 20080320063 | Transacting accesses via unmanaged pointers - Various technologies and techniques are disclosed for transacting accesses via unmanaged pointers in a transactional memory system. A transactional memory system is provided. Source code is analyzed to identify operations that create unmanaged pointers. Information is tracked about the targets of unmanaged pointer values in pointer variables. The target information is used to determine how accesses through an unmanaged pointer argument are to be transacted. When an unmanaged pointer is created, a descriptor of the target with the resulting pointer value is associated with the location. Within the method that creates the unmanaged pointer, the target can be identified using the descriptor, thereby enabling accesses to be transacted. When an unmanaged pointer is being passed as an argument, a descriptor is also passed as an argument to allow the unmanaged pointer target to be identified. | 12-25-2008 |
