Presented herein are system(s) and method(s) for motion estimation using camera movements. In one embodiment, there is presented a video camera system for providing video data. The video camera system comprises a video camera, and a circuit. The video camera captures video data. The circuit records information that indicates tracking movements of the video camera.

Presented herein are a system, method, and apparatus for retrieving an object from memory. The object can be stored in a manner, such that the first byte of the object and the last byte of the object are in the middle of the memory data words. The object is retrieved by a direct memory access controller. The direct memory access controller, when provided with a read transaction with the starting address and the ending address of the object, retrieves the data words storing the object, and overwrites the portions of the data word that precede and follow the object.

Direct memory accessing for fetching macroblocks

The present invention is directed to a line address computer for calculating the starting line addresses for lines of a decoded frame. The starting addresses for a display frame are provided to the line address computer by a host processor. The line address computer determines the starting line addresses for subsequent lines by appropriately incrementing the line addresses of previous lines.

Presented herein are video decoding system(s), method(s), and apparatus for repeating a last line to a scalar or compositor or capture. A first parameter is provided to a first register indicating that a picture comprises a first number of lines, and a second parameter is provided to a second register, indicating that the picture comprises a second number of lines.

Presented herein are systems and methods for clock rate determination. A bitstream is sampled by sampling a transmitted clock signal at a rate corresponding to a receiver clock signal, and measuring an average number of consecutive samples that have a same state selected from a first state and a second state.

Presented herein is a system for storing macroblocks for concatenated frames. A decoder system comprises a frame buffer. The frame buffer comprises one or more rows. A particular one of the rows stores macroblocks from a plurality of frames.

A method and system for testing a memory controller are provided herein. A test sequence may be generated within the memory controller. A test output may also be generated within the memory controller, where the test output is associated with the test sequence. The test output may then be verified. The test sequence may comprise one or more of a control command, a memory address, and/or a DQM signal. The test output may be generated by a sequencer. The test output may be verified by a cyclic redundancy check (CRC) module. The test sequence may also comprise random write data. The random write data may be communicated to a memory controller write data output via a write data bus.

Custom logic BIST for memory controller

Presented herein are systems and methods for pixel reordering and selection. A decoded frame is stored in a frame buffer with a particular pixel order and byte order. A pixel feeder fetches portions of the decoded frame and stores portions of the frame in a double buffer with the same pixel order and byte order. An endian swizzle converts the byte ordering to a predetermined format, as needed. Reordering logic changes the pixel order to a predetermined order. Selection logic selects luma and chroma pixels from fetched pixels and provides the luma pixels to a luma pixel register, chroma Cr pixels to a chroma Cr pixel register, and chroma Cb pixels to a chroma Cb pixel register.

Pixel reordering and selection logic

Presented herein is a system and method for a line address computer for providing line addresses in multiple contexts for interlaced to progressive conversion. A feeder fetches a first line from a top field, fetches a first line from a bottom field corresponding to the top field, after fetching the first line from the top field, and fetches a second line from the top field after fetching the first line from the bottom field. The second line from the top field is adjacent to the first line in the top field.

Presented herein is a line address computer for providing chroma coefficients to a chroma filter. At each horizontal synchronization pulse, the line address computer provides a set of interpolation weights to a chroma filter. The chroma filter uses the provided set of weights to interpolate pixels in chroma pixel positions in a display format from chroma pixels in another format.

Methods of setting numerically controlled delay lines using step sizes based on a delay locked loop lock value are presented herein. In one embodiment, a method may comprise, for example, one or more of the following: calculating an offset value for at least one NCDL; and interpolating a new offset value for the at least one NCDL, based on a change in a delay locked loop (DLL) output value from a previous DLL output value to a new DLL output value.
