MIPI CSI 2 Receiver

To-do List

• Primary format decoding
  • [x] RGB888
  • [x] RGB565
  • [x] YUV422 8-bit
  • [x] RAW8
  • [ ] RAW10
• Tests
  • [x] D-PHY
  • [x] CSI-2
  • [ ] Decoding
• Error-checking and correction
  • [ ] Header ECC
  • [ ] Footer Checksum
• N-lane
  • [x] 1 lane
  • [x] 2 lane
  • [ ] 3 lane
    • Roadblock: will receive more bytes than the 32-bit buffer
      • Consider long packet with 8 bytes
      • First 3 from header go from corresponding lanes
      • Header byte 4 comes from lane 1, Data byte 1, 2 come from lanes 2 & 3
      • Data byte 3, 4, 5 (!) come from lanes 1, 2, & 3
      • Thus, you are stuck with extra, on the same clock the user gets the buffer
  • [x] 4 lane
