Abstract

A unit of operation is described. The execution unit includes an arithmetic logic unit (ALU) circuit having a first input to receive a first value and a second input to receive a second value. The ALU circuit includes circuitry to determine the absolute value of the first value and add the absolute value to the second value. A first input is coupled to an output of another ALU having a first data path of register space and an execution unit circuit as an alternative source of a first value. The second input is coupled to a second data path having register space as a source of a second value.

Description

technical field [0001] The field of the invention relates generally to computing science, and more specifically, to a circuit that performs an absolute value and sum operation of two input values. Background technique [0002] Image processing often involves manipulation of pixel values ​​organized into arrays. Here, the spatially organized two-dimensional array captures the two-dimensional nature of the image (additional dimensions may include time (eg, two-dimensional image sequence) and data type (eg, color)). In common scenarios, arrays of pixel values ​​are provided by cameras that generate still images or frame sequences to capture moving images. Traditional image processors are usually at either end of the two extremes. [0003] The first extreme performs image processing tasks as a software program running on a general-purpose processor or general-purpose processor (eg, a general-purpose processor with vector instruction enhancement). Although the first extreme ty...
