Sheet generator for image processor

Abstract

A sheet generator circuit is described. The sheet generator includes electronic circuitry to receive a line group of image data including multiple rows of data from a frame of image data. The multiple rows are sufficient in number to encompass multiple neighboring overlapping stencils. The electronic circuitry is to parse the line group into a smaller sized sheet. The electronic circuitry is to load the sheet into a data computation unit having a two dimensional shift array structure coupled to an array of processors.

Description

technical field [0001] The field of the invention relates generally to image processing, and more particularly to data slice generators for image generators. Background technique [0002] Image processing generally involves manipulating pixel values ​​organized into arrays. Here, a spatially organized two-dimensional array captures the two-dimensional nature of the image (additional dimensions may include time (e.g., sequence of two-dimensional images) and data type (e.g., color). In a typical scenario, an array of pixel values Supplied by cameras that already generate still images or frame sequences to capture images in motion. Traditional image processors typically fall into one of two extremes. [0003] The first extreme performs image processing tasks as a software program executing on a general-purpose processor or general-purpose processor (eg, a general-purpose processor with vector instruction enhancement). While the first extreme typically provides a highly genera...

Problems solved by technology

However, using custom-designed fixed-function circuits often results in a processor that can only perform a limited set of tasks

Thus, in the second extreme there is a lack of a broadly general programming environment (which is associated with the first extreme)
