Few years back I used to work on BlackFin and I used to remember that it was always pitched against OMAP. Technical marketing guys from TI and ADI used to always have slides with benchmark numbers comparing BlackFin and OMAP.

Looks like ADI's Blackfin is going to compete with TI's 1 GHz OMAP4 dual core processor as the features look similar?

There is no doubt the demand of embedded vision is growing. The more advanced driver assist systems is installed in a car, the safer we will be. I am sure there are tons of researchers developing optimized algorithm to deal with the situations - “forward collision warning/mitigation” and “pedestrian detection functions,” but also “intelligent high beam control,” “traffic sign recognition” and “lane departure warning features". Soon, the google autodriving algorithm will be embedded into the next-generation processor. In real time vision, the data transfer among camera, memory and processor is substantial. Given the resolution 1280 x 960 of 8 bits grey scale, the amount of data is 1.3MB. A 10 frame per second capturing, the data rate is 13MBps, i.e. ~100Mbps. This is just speaking of data transfer from camera to memory or memory to processor. If the vision algorithm includes 3 stages processing, the data transfer between processor and memory will be increased to 3 times, i.e. 300Mbps. I am really interested in learning how to reduce the memory bandwidth requirement. Any more infos or research papers are welcomed. ;)
