摘要:
A system and method that determines the direction of an edge in a video image using a gradient of the edge in a first direction and a gradient of the edge in a second direction. The system uses the sign of the product of the gradient in the first direction and the gradient in the second direction along with a ratio of multiples of the two gradients to determine the direction of the edge. The direction may correspond to an angle range, where the ratio of the gradients corresponds to a trigonometric function of the angle of the edge.

A system and method that abstracts an interrupt from a group of interrupts, which may occur in a module, to call another module. Abstracting one interrupt from a group of interrupts allows the called module to deal with only one interrupt. The choice of the interrupt may be based on the configuration of the module from which the interrupts are originated. In an embodiment of the present invention, the abstracted interrupt triggers an event. When the triggered event is completed, an interrupt may be fired off to the target module. An interrupt handler in the target module or an external interrupt handler may handle the interrupt that calls the target module.

A television on a chip (TVOC) system that provides a cost effective approach for providing television functionality on a single integrated circuit chip is disclosed. A TVOC includes the functionality necessary to receive and display television signals in a variety of input and output formats. A TVOC can be used in set-top boxes for cable and satellite television, or directly within a television. All functionality provided can be provided on a single integrated circuit. TVOC includes a data transport module, an IF demodulator, a digital audio engine, an analog audio engine, a digital video engine, and an analog video engine. The TVOC also includes three sets of interfaces including output interfaces, control interfaces and ancillary interfaces. Further features and embodiments provide enhanced functionality and increased efficiencies.

A method and system automatically harmonizes access to a given software application program via different access devices. Through use of the method and system, a financial institution can provide access to a given application (such as, for example, automatic bill payment services) to customers using different access devices such web browsers, screen phones and personal computers. A single application program is all that needs to be written and maintained by the financial institution. Also, the method and system enables financial institutions to “leverage” existing programs because now the institution can automatically “project” its existing stock of program services unto new access devices—devices which may not have even existed at the time the program was created. By receiving information from the user via the user's access device, including information identifying the type of device being used and the application program the user wishes to access, the present invention solves these problems. The application program is then accessed and the information to be displayed to the user is identified. This information is automatically translated into a format which is compatible with the device, including its display, and sent to the device for display. The user, in turn, inputs information in response to the displayed information and this input information is automatically translated into a format which is compatible with the application program and is sent to the application program. The response generated by the application program is automatically translated to be compatible with the device and is sent to the device.

Embodiments of a distributed memory controller system implemented on a single integrated circuit device are described. In one embodiment, a memory controller that provides an interconnection circuit between a first plurality of memory devices to a second plurality of memory clients includes a ring bus to route at least one of the memory request and data return signals between the memory clients and the memory devices. The ring bus is configured in a ring topography that is distributed across a portion of an integrated circuit device, resulting in a reduction in the maximum wiring density at the center of memory controller. The ring bus structure also reduces the overall number of interconnections as well as the number of storage elements, thus reducing the total area used by the memory controller.

Systems and methods are disclosed for filter modules in a video display system or network. One embodiment relates to a method for operating a filter module in a video display network comprising determining a picture type, display type and operation of the display network. The method further comprises determining, in real time, a filter configuration from a plurality of possible filter configurations based on the determined picture type, display type and operation.

Methods and apparatus are provided for efficiently normalizing and denormalizing data for cryptography processing. The normalization and denormalization techniques can be applied in the context of a cryptography accelerator coupled with a processor. Hardware normalization techniques are applied to data prior to cryptography processing. Context circuitry tracks the shift amount used for normalization. After cryptography processing, the processed data is denormalized using the shift amount tracked by the context circuitry.
