Abstract
Methods and apparatus to manage image signal processor (ISP) data traffic is provided. The apparatus includes an ISP having an ISP front-end configured to receive image data and a first memory configured to store the image data. The ISP front-end is further configured to output the image data stored in the first memory to a second memory via a memory link in response to the image data stored in the first memory reaching a size threshold. Another apparatus includes apparatus includes a camera sensor configured to output image data in a camera mode, an ISP on a die, a camera link coupling the camera sensor and the ISP, a memory, and a memory link coupling the ISP and the memory. The memory link is configured to enter a low-power mode in the camera mode.
