  • Image rotation circuit
    Patent number: 4916746
    Abstract: An image rotation circuit comprises a first-in-first-out memory (FIFO) for holding a block of data representing a portion of an image. Data is read out of the FIFO a word at a time, and written back into the FIFO with a displacement of one bit position. Thus, the data effectively travels around a spiral data path, producing a serial output stream. A shift register assembles the output data into words, representing the rotated image.
