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.

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, 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.
