BeMicro SDK - Whats instructions are implemented from factory?

Hi,

I'm working with BeMicro SDK development board to update some C standard library, but I need to know where i can find the instruction set implemented on the Ciclone IV that have the BeMicro SDK from factory.

I've toke a look at the Altera manuals and BeMicro SDK documentation but I can't found this information.

Does anyone help me with this? I really need help because I can't optimize functions if I don't know what Ciclone IV have implemented inside from factory on BeMicro SDK.

Thanks.

Fabricio.
