Abstract

A processor and method for scaling an image are disclosed. A specific embodiment of the processor includes: an off-chip memory, a communication circuit, a control circuit, and an array processor, wherein: the off-chip memory is configured for storing a to-be-scaled original image; the communication circuit is configured for receiving an image scaling instruction; the control circuit is configured for executing the image scaling instruction, and sending a calculation control signal to the array processor; and the array processor is configured for calculating in parallel channel values of N channels in a target pixel using N processing elements in the array processor under the control of the calculation control signal based on a width scaling factor, a height scaling factor, and channel values of N channels in extracted pixel data. The embodiment has improved the processing speed of an image scaling operation.
