Hey All, Thanks a lot for the replies. I have the development keys. But the algorithm and some intellectual property needs to be licenced from the 4C entity guys to implement it. As of now I just want to test the CPRM functionality. So licensing the algo for a prototype testing is a huge cost.
That is why I was looking for an already implemented solution - hardware/software - so that I can just test. If it does not suite our needs, then I have just paid for a chip only and not for a whole license. Seems like there is no other way out than shelling out money for the license. :( Thanks anyways, Midhun.
