摘要： A system and method of processing an image is disclosed. A particular method of determining whether a particular pixel of an image is a feature candidate includes receiving data corresponding to a subset of a plurality of pixels surrounding the particular pixel. Each of the plurality of pixels may be from the image. The method further includes excluding the particular pixel from consideration as a feature candidate based on a comparison of values of the data to a comparison value. The comparison value may be based on an attribute value of the particular pixel and a threshold attribute value.

摘要： Method and apparatus for performing two independent sum-of-absolute-difference (SAD) operations when receiving a single instruction (505, 705) is provided. The two operations may be performed in parallel. The operations process values stored in two source registers (405, 410) and the results are stored to a destination register (425). The source and destination registers each have two independently accessible sections, whereby a first SAD operation (401) can access a first section while a second independent SAD operation (402) can simultaneously access a second section of the register. The first SAD operation is performed on values in a first section of the source registers, the result being stored to a first section of the destination register. The second SAD operation is performed on values in a second section of the source registers, the result being stored to a second section of the destination register. The values may comprise pixel values.

摘要： In a particular embodiment, a method is disclosed that includes executing a single instruction to identify a location within a table stored at a memory. The single instruction is executable by a processor to extract bit field data from a first register and insert the bit field data into an index portion of a second register. The second register includes a table address portion and an index portion. The table address portion includes a table address identifying a memory location associated with a table. The table address and the bit field data combine to form an indexed address to an element within the table.

摘要： A method and system to combine multiple register units within a microprocessor, such as, for example, a digital signal processor, are described. A first register unit and a second register unit are retrieved from a register file structure within a processing unit, the first register unit and the second register unit being non-adjacently located within the register file structure. The first register unit and the second register unit are further combined during execution of a single instruction to form a resulting register unit. Finally, the resulting register unit is stored within the register file structure for further processing. Alternatively, a first half word unit from the first register unit and a second half word unit from the second register unit are retrieved. The first half word unit and the second half word unit are further input into corresponding high and low portions of a resulting register unit to form the resulting register unit during execution of a single instruction. Finally, the resulting register unit is stored within the register file structure for further processing.

摘要： A system and method of processing an image is disclosed. A particular method of determining whether a particular pixel of an image is a feature includes receiving data corresponding to a plurality of pixels (from the image) surrounding the particular pixel. The method further includes determining a set of comparison results, each corresponding to one of the plurality of pixels and indicating a result of comparing an attribute value corresponding to one of the plurality of pixels to a comparison value (based on a particular attribute value of the particular pixel and a threshold value). The method further includes performing a processor-executable instruction that, when executed by a processor, causes the processor to identify a subset of the set of comparison results that indicate the particular pixel is the feature. The identified subset may be a consecutive order of pixels of the plurality of pixels.
