    摘要: A method is described. The method includes configuring a first instance of object code to execute on a processor. The processor has multiple cores and an internal network. The internal network is configured in a first configuration that enables a first number of the cores to be communicatively coupled. The method also includes configuring a second instance of the object code to execute on a second instance of the processor. A respective internal network of the second instance of the processor is configured in a second configuration that enables a different number of cores to be communicatively coupled, wherein, same positioned cores on the processor and the second instance of the processor have same network addresses for the first and second configurations. A processor is also described having an internal network designed to enable the above method.

    摘要: An apparatus is described that include a line buffer unit composed of a plurality of a line buffer interface units. Each line buffer interface unit is to handle one or more requests by a respective producer to store a respective line group in a memory and handle one or more requests by a respective consumer to fetch and provide the respective line group from memory. The line buffer unit has programmable storage space whose information establishes line group size so that different line group sizes for different image sizes are storable in memory.

    摘要: An execution unit 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 an absolute value of the first value and to add the absolute value to the second value. The first input is coupled to a first data path having register space and an output of another ALU of the execution unit circuit as alternative sources of the first value. The second input is coupled to a second data path having the register space as a source for the second value.

    摘要: 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.

    摘要: A method is described. The method includes simulating execution of an image processing application software program. The simulating includes intercepting kernel-to-kernel communications with simulated line buffer memories that store and forward lines of image data communicated from models of producing kernels to models of consuming kernels. The simulating further includes tracking respective amounts of image data stored in the respective line buffer memories over a simulation runtime. The method also includes determining respective hardware memory allocations for corresponding hardware line buffer memories from the tracked respective amounts of image data. The method also includes generating configuration information for an image processor to execute the image processing application software program. The configuration information describes the hardware memory allocations for the hardware line buffer memories of the image processor.

    摘要: A method is described. The method includes calculating data transfer metrics for kernel-to-kernel connections of a program having a plurality of kernels that is to execute on an image processor. The image processor includes a plurality of processing cores and a network connecting the plurality of processing cores. Each of the kernel-to-kernel connections include a producing kernel that is to execute on one of the processing cores and a consuming kernel that is to execute on another one of the processing cores. The consuming kernel is to operate on data generated by the producing kernel. The method also includes assigning kernels of the plurality of kernels to respective ones of the processing cores based on the calculated data transfer metrics.
