Abstract: Disclosed is a method and apparatus for implementing a virtual mouse. In one embodiment, the functions implemented include activating the virtual mouse, determining a location of a cursor icon associated with the virtual mouse, and deactivating the virtual mouse. In various embodiments, the position of virtual mouse is determined by a processor based upon an orientation or position of a finger touching a touchscreen and a measured or calculated pressure applied by the finger to the touchscreen.

Abstract: A method for processing an image is described. Mask bits are determined for a current pixel. The mask bits indicate intensity comparisons between the current pixel and multiple neighboring pixels. The mask bits also indicate whether each of the current pixel's neighboring pixels have been processed. A next pixel is selected for processing based on the mask bits.

Abstract: A method, an apparatus, and a computer program product for processing touchscreen information are provided. The method may include receiving touchscreen data that includes node values representative of signals generated by a touchscreen panel, generating a first data frame including difference values, and transmitting the first data frame over a control data bus. Each of the difference values may be calculated as a difference between one of the node values and a different node-related value wherein the first data frame has a predefined size. The first data frame may be configured to permit a receiver of the first data frame to reconstruct the touchscreen data without information loss.

Abstract: A method for memory utilization by an electronic device is described. The method includes transferring a first portion of a first decision tree and a second portion of a second decision tree from a first memory to a cache memory. The first portion and second portion of each decision tree are stored contiguously in the first memory. The first decision tree and second decision tree are each associated with a different feature of an object detection algorithm. The method also includes reducing cache misses by traversing the first portion of the first decision tree and the second portion of the second decision tree in the cache memory based on an order of execution of the object detection algorithm.

Abstract: A method for calculating a feature descriptor on a single instruction, multiple data (SIMD) processor is described. The method includes generating histogram bin indexes in a first register. The method also includes generating weights in a second register. The method further includes updating an entire histogram table in a register file based on the histogram bin indexes and the weights without storing any histogram bin to memory. Histogram bins are updated in parallel with a single instruction.

Abstract: A method includes executing, at a processor, a dedicated arithmetic encoding instruction. The dedicated arithmetic encoding instruction accepts a plurality of inputs including a first range, a first offset, and a first state and produces one or more outputs based on the plurality of inputs. The method also includes storing a second state, realigning the first range to produce a second range, and realigning the first offset to produce a second offset based on the one or more outputs of the dedicated arithmetic encoding instruction.
