Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for restructuring an image processing pipeline. The method includes compiling program code targeted for an image processor having programmable stencil processors composed of respective two-dimensional execution lane and shift register circuit structures. The program code is to implement a directed acyclic graph and is composed of multiple kernels that are to execute on respective ones of the stencil processors, wherein the compiling includes performing any of: horizontal fusion of kernels; vertical fusion of kernels; fission of one of the kernels into multiple kernels; spatial partitioning of a kernel into multiple spatially partitioned kernels; or splitting the directed acyclic graph into smaller graphs.

Abstract: An apparatus that includes a program controller to fetch and issue instructions is described. The apparatus includes an execution lane having at least one execution unit to execute the instructions. The execution lane is part of an execution lane array that is coupled to a two dimensional shift register array structure, wherein, execution lane s of the execution lane array are located at respective array locations and are coupled to dedicated registers at same respective array locations in the two-dimensional shift register array.

Abstract: An apparatus is described that includes an execution unit having a multiply add computation unit, a first ALU logic unit and a second ALU logic unit. The ALU unit is to perform first, second, third and fourth instructions. The first instruction is a multiply add instruction. The second instruction is to perform parallel ALU operations with the first and second ALU logic units operating simultaneously to produce different respective output resultants of the second instruction. The third instruction is to perform sequential ALU operations with one of the ALU logic units operating from an output of the other of the ALU logic units to determine an output resultant of the third instruction. The fourth instruction is to perform an iterative divide operation in which the first ALU logic unit and the second ALU logic unit operate during to determine first and second division resultant digit values.

Abstract: A method is described that includes executing a convolutional neural network layer on an image processor having an array of execution lanes and a two-dimensional shift register. The executing of the convolutional neural network includes loading a plane of image data of a three-dimensional block of image data into the two-dimensional shift register. The executing of the convolutional neural network also includes performing a two-dimensional convolution of the plane of image data with an array of coefficient values by sequentially: concurrently multiplying within the execution lanes respective pixel and coefficient values to produce an array of partial products; concurrently summing within the execution lanes the partial products with respective accumulations of partial products being kept within the two dimensional register for different stencils within the image data; and, effecting alignment of values for the two-dimensional convolution within the execution lanes by shifting content within the two-dimensional shift register array.

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.
