Abstract: An image processor is described. The image processor includes an I/O unit to read input image data from external memory for processing by the image processor and to write output image data from the image processor into the external memory. The I/O unit includes multiple logical channel units. Each logical channel unit is to form a logical channel between the external memory and a respective producing or consuming component within the image processor. Each logical channel unit is designed to utilize reformatting circuitry and addressing circuitry. The addressing circuitry is to control addressing schemes applied to the external memory and reformatting of image data between external memory and the respective producing or consuming component. The reformatting circuitry is to perform the reformatting.

Abstract: 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.
