Abstract:
1. An interface processor for providing random access to an image frame from an image sensor, the processor comprising: a memory; a sensor control module configured to transmit a wake signal to the image sensor, wherein the sensor control module is further configured to store a configuration mapping associated with the image sensor, and wherein the configuration mapping comprises one or more register addresses and one or more register entries for controlling the image sensor, wherein the sensor control module is further configured to receive the configuration mapping prior to transmitting the wake signal; a pixel stream module configured to receive a data signal at an output data rate from the image sensor following transmission of the wake signal and store the data signal in the memory, wherein the data signal comprises a plurality of pixels that correspond to the image frame; and a frame access module configured to receive an address signal, determine a selected pixel of the plurality of pixels referenced by the address signal, retrieve the selected pixel from the memory, and transmit an image signal comprising the selected pixel.
