摘要： A method and system for reducing the complexity of block motion estimation is described. According to the invention, the block distortion measure is determined by calculating a partial error result using a proportion of pixels in the block, comparing the partial error result with a threshold value and rejecting blocks where the partial error result is greater than the threshold value, and calculating a full error result for non-rejected blocks only. The threshold value is a function of the current minimum partial error result, and is preferably the current minimum partial error result multiplied by a threshold constant lambda. Another aspect of the invention provides a video transport scheme which exploits the different importance of both GOP and re-synchronisation levels. According to this aspect, an unequal loss protection (ULP) philosophy is utilized. That is, the bit stream data is partitioned into several parts according to different importance, and the parts are unequally protected against packet loss using forward error correction codes.

摘要： A method ( 400 ) and an apparatus for AVC intra prediction to code digital video comprising a plurality of pictures are disclosed. The method comprises the steps of: generating ( 410 ) edge directional information for each intra block of a digital picture; and choosing ( 420 ) most probable intra prediction modes for rate distortion optimisation dependent upon the generated edge directional information. The edge directional information may be generated by applying at least one edge operator to the digital picture. The edge direction histogram may sum up the amplitudes of pixels with similar 15 directions in the block. The method may further comprise the step of intra coding ( 430 ) a block of the digital picture using the chosen most probable intra prediction modes.

摘要： Apparatus and methods are disclosed for solving Mixed Integer Programming (MIP) problems, such as Security Constrained Unit Commitment (SCUC) problems used by power grid authorities to perform day-ahead market clearing. In certain examples, a plurality of threads of a software tool implementing a concurrent optimizer can be executed concurrently and sequentially to generate new solutions to a SCUC problem for an upcoming planning horizon. Data can be shared among the concurrently executing threads, such as intermediate/incumbent solutions and hints regarding the fixing of variables and constraints to reduce the size of the SCUC problem. In some examples, the threads are seeded with historical solutions from prior planning horizons. The software tool can select a best solution from the solutions generated by the threads, and determine dispatch instructions for a device coupled to the power grid for the upcoming planning horizon based at least in part on the selected solution.

摘要： A method and system for computing 2-D DCT/IDCT which is easy to omplement with VLSI technology to achieve high throughput to meet the requirements of high definition video processing in real time is described. A direct 2-D matrix factorization approach is utilized to compute the 2-D DCT/IDCT. The 8x8 DCT/IDCT is computed through four 4x4 matrix multiplication sub-blocks (1320, 1330, 1340, 1350). Each sub-block is half the size of the original 8x8 size and therefore requires a much lower number of multiplications. Additionally, each sub-block can be implemented independently with localized interconnection so that parallelism can be exploited and a much higher DCT/IDCT throughput can be achieved.

摘要： According to different embodiments of the present invention, various methods, devices and systems are described for managing power in charge pumps in a non-volatile memory system having a high voltage charge pump and associated regulator. A method includes the following operations, receiving an operation command corresponding to an operation, pumping up a charge pump output voltage to a desired output voltage, turning off the regulator and the charge pump when the output voltage is approximately the desired output voltage compensating for charge sharing by turning on the charge pump and setting a pump clock rate to a slow clock rate in order to avoid overshooting the desired output voltage by the charge pump while the operation is being carried out, and compensating for junction leakage by turning on the regulator and the charge pump until the charge pump output voltage is the desired output voltage.
