Abstract: A processor having a limited amount of local memory for storing code and/or data utilizes a program stored in external memory. The program stored in external memory is configured into blocks which can be loaded individually into the local memory for execution. Queuing the individual blocks of code allows the program to be executed by the processor and also facilitates loading of the subsequent code to be executed. A semaphore system can be utilized to indicate which blocks of local memory are available/unavailable. A group of transfer parameters as queue entries allow code and data for an algorithm to be transferred between both local and external memory.

Abstract: An over-sampled sequence detector operates on sampled data and tracks the detection reliability of the sampled data. The detector separately analyzes sample sequences for different sampling phases and then picks a sample sequence that allows for the most reliable detection. For the different sampling phases, the detector inspects some amount of look-behind and look-ahead information in order to improve upon simple symbol-by-symbol detection. The over-sampled information is used to further improve detection performance.

Abstract: Global-adaptive deinterlacing systems and methods for reducing scintillation and feathering artifacts. Motion adaptive deinterlacing (MADI) local motion quantization thresholds are adaptively adjusted according to the amount of global motion present in the video sequence, thereby minimizing scintillation and feathering artifacts when deinterlacing the fields. A set of global motion scenarios are defined for the purpose of classifying fields, and a number of global motion indicators are used to detect on a field-by-field basis different global motion scenarios.

Abstract: Disclosed is a method for generating transfer curves for adaptive contrast enhancement. Transfer curves are generated so as to enhance the bright pixels in mostly dark images and the dark pixels in mostly bright images. For a dark image, a transfer curve is generated which increases luminance in high-luminance regions of the image without substantially changing the luminance in the mid- and low-luminance regions of the image. For a bright image, a transfer curve is generated which decreases the luminance in the dark areas of the image without substantially changing the luminance in the mid- and high-luminance regions of the image. For a medium-bright image, a transfer curve is generated with increases the luminance in the high-luminance range and decreases the luminance in the low-luminance range of the histogram without substantially changing the luminance in the medium-luminance range of the image.

Abstract: A video controller having a processor for processing executable instructions and associated data and a number of data ports, a method of acquiring extended display identification data (EDID) by a requesting one of the data ports is described. When on-board power supply is activated, an off-board power supply is deactivated and then the now active on-board power supply provides power to a memory device used to store the EDID and the executable instructions and associated data and to an on-board clock circuit capable of providing a high frequency clock signal. The on-board clock circuit, in turn, provides the high frequency clock signal from the on-board clock circuit to the memory device and if a memory read operation had been in progress when the on-board power supply was activated, then the memory read operation is completed.

Abstract: Managing power in a display controller having an on-board power supply coupled to a host device having an off-board power supply by way of a connector is described. If the on-board power supply is active, then power is supplied to the display controller by the off-board power supply by way of the connector and a low frequency clock arranged to provide a low frequency clock signal is turned on. Alternatively, when it is determined that the on-board power supply is active, then power is supplied to the display controller by the on-board power supply only, the low frequency clock is turned off and a high frequency clock arranged to provide a high frequency clock signal is turned on.
