Hi I am novice to the embedded system programming. I need to implement RSA on the above microcontroller using a special FameX coprocessor present for the very purpose. I am trying to use the keil compiler, linker and simulator but I am not able to contemplate how and where to start. I know I have to write some code in c and some in assembly to get more control over the execution but I am not able to decide what to write in which language and which one to write first. Anybody having some prior experience, please help me. Any small help is appreciated like pointing to some references or sample programs etc. I believe somebody might have already implemented it for this processor. If such code exists in public domain, I can also reuse it.
Thanks in advance, venkat.
