now my ccs project required:

Input Video Source:2048x2048 @12bit

h.264 lib: h.264 hp encode lib(v01.00.00) by ti

h264 encode output: 4Mbps@10fps

Can realize this project by c6672 with two cores?

Hi David,

H264HP encoder does not support 12 bit input. So you cannot realize specified project.

if input video image is 2048x2048@8bit ,can realize this project by c6672 with one core?

Codec supports beyond HD resolution till 4kx4k functionally, provided application gives required memory buffers to codec.

Performance is not assured beyond HD resolution. with one core how many fps you are expecting? for sure 10fps is not possible.

Hi David,

As per data sheet for HD 30fps -> 7360Mh i.e 1 fps -> 246Mhz. when you consider 2K encoding for 1fps translates to 492Mhz(Assuming 2K is twice complex as HD due to resolution).

You need at least 4920Mhz to get 10fps. So using 4 cores it is possible.
