What is the best development board for learning embedded arm9 video processing graphic interface?

Oh, look at your video resolution and compression algorithms, basically, all the way to real-time 24-frame 640 * 480 video (H264) on the absolute eat all the CPU resources of the 2440, if you do not use a complex operating system (linux, wince) resources to save some, and then optimize the algorithm as much as possible, but also absolutely can not support the three-way video encoding.

Video encoding algorithms are many, if the video stream is not compressed, or just learning, hands-on try, do not take into account the efficiency of the problem (for example, the first capture image, the image stored as a file, and then encode the file), the 2440 is a very economical choice, if you intend to be practical, it is recommended to give up arm9, with the newer platforms, such as arm cortex A system of the A8 or A9, running at 1.5 times the frequency of the A8, or A9, running at 1 times the frequency of the A8. or A9, running frequency in 1G or so, the efficiency of arm9 4 times, can only occupy 100MHz computing power to realize all the way video encoding. If the cheaper ones, the xscal series can also be used, with a frequency of 700~1G, they should be able to do the job.

There is nothing too good in terms of information, most of the information was not used at the time of doing, basically the problem encountered on the information is not, have to turn over the forums themselves, the information is written on how to be right, do not write if it is not right how to find ....
