4.3 ADAS Use Case

Figure 4-3 shows high-level block diagram for a common ADAS use-case where

  • 1x 8Mpixel @30 fps is used for front camera
  • 1x 1Mpixel camera is used for DMS and
  • 4 x 2Mpixel @30 fps is used for 3-D SRV.

These cameras are remotely connected over FPDLink serializer and deserializer.

For FDPLink-based multi-camera setup, see [5].

Table 4-3 shows total utilization for this use-case.
