DATA REORDERING USING BUFFERS AND MEMORY

摘要

Apparatus and methods are disclosed for reordering data received in a non-contiguous order into a contiguous order. In one example of the disclosed technology, an apparatus includes a number of input buffers comprising at least a first, first-in first-out (FIFO) input buffer and a second FIFO input buffer, a number of FIFO output buffers, and a reorder unit configured to store a first portion of non-contiguous data received from an image sensor in the first input buffer, store a second portion of the received data in the second FIFO input buffer, store a respective pixel of data output by the first and second FIFO input buffers at a first address location in the memory, and traverse the memory according to an order to store the respective pixels in a FIFO output buffer. The apparatus can thus be used to reorder pixel data prior to further image processing.
