description: |
  The Raspberry Pi PiSP Image Signal Processor (ISP) Back End is an image
  processor that fetches images in Bayer or Grayscale format from DRAM memory
  in tiles and produces images consumable by applications.

  The full ISP documentation is available at
  https://datasheets.raspberrypi.com/camera/raspberry-pi-image-signal-processor-specification.pdf
