摘要: Consistent with one aspect, a circuit arrangement performs a variety of operations for tasks relating to motion and includes one or more ALU components. One such circuit arrangement is adapted to provide a picture phone that includes: a telephone transceiver; a camera; a display; a digital signal processor (DSP), including a multiplier unit, adapted to perform image data (de)compression; and a reduced instruction set computing (RISC) processor for routing data among the camera, the display, the DSP, and the telephone transceiver. Further, a memory is used to store (de)compression algorithm code executed by the DSP and data routing control code executed by the RISC processor

摘要: A multimedia processor contains a general purpose RISC and video processors which operate in parallel to execute software for combined video and audio bit stream coding and decoding. The RISC processor controls operation of the multimedia processor and performs bit stream parsing and coding, audio compression and decompression, and general processing for embedded applications. The video processor performs video encoding and decoding functions such as scaling, filtering, decimation, and DCT transforms. The RISC processor and the video processor each have separate data buses which are interconnected through a portal circuit and a Huffman codec. Each data bus has a DMA controller which transfers data to and from a memory interface to an external memory. DMA channels serve I/O interface resources coupled to the data buses and can form buffers in the external memory. This reduces the need for on-chip FIFO buffers and separate buffers between the multimedia processor and attached devices.

摘要: A programmable motion estimator includes one dual ported memory for storing an image block, the prediction error, and a temporary block used in interpolation, and a pixel-group random access dual ported memory for storing a search window. The two ports of the two memories are selectively applied to an arithmetic logic unit, or ALU, through a multiplexer. One output of the ALU provides an absolute difference, which is furnished to a tree adder. Another output of the ALU provides an average value or a difference value, as selected, which is routed to the inputs of the image memory and the search memory. In motion vector searching, the ALU performs pixel absolute difference arithmetic using the pixel groups from the image memory and from the search memory, and determines a sum of absolute differences in the tree adder. In half pixel interpolation, the ALU performs pixel averaging arithmetic using pixel groups from the search memory, and writes back to the search memory. In quarter pixel interpolation, the ACU performs pixel averaging arithmetic using pixel groups from the image and search memories, and writes back to the search memory. In some quarter pixel interpolations, temporary interpolated blocks from the image memory are used to interpolated quarter pixel blocks. These temporary blocks are obtained by pixel averaging in the ALU using pixel groups from the search memory. In error prediction determination, the ALU performs pixel subtraction using the pixel groups from the image memory and from the search memory, and writes back to the image memory.
