Abstract: A method is disclosed for efficiently calculating a median value of a high-order array in a Single Instruction Multiple Data (SIMD) processor. Values of the high-order array are sorted vertically in each column followed by sorts on each individual row. After the sort, selective diagonal values of the sorted high-order array are used to form a low-order array to calculate the median of the high-order array. The median calculation using selective diagonal values of the high-order array in a low-order array significantly improves SIMD processor efficiency and throughput.

Abstract: A method for determining a median value of an array of pixels in a vision system may be performed in an efficient manner using the parallel computing capabilities of a SIMD processing engine. Each column of an array may be sorted in ascending (descending) order to form a first sorted array. Each row of the first sorted array may be sorted in ascending (descending) order to form a second sorted array. A pixel may be selected as the median value from a diagonal portion of the second sorted array, wherein the diagonal portion bisects a lower value region and a higher value region of the second sorted array.

Abstract: A video decoder includes a memory (140) operable to hold entropy coded video data accessible as a bit stream, a processor (100) operable to issue at least one command for loose-coupled support and to issue at least one instruction for tightly-coupled support, a bit stream unit (110.1) coupled to said memory (140) and to said processor (100) and responsive to at least one command to provide the loose-coupled support and command-related accelerated processing of the bit stream, and a second bit stream unit (110.2) coupled to said memory (140) and to said processor (100) and responsive to said at least one instruction to provide the tightly-coupled support and instruction-related accelerated processing of the bit stream. Other encoding and decoding processors, circuits, devices, systems and processes are also disclosed.
