256-bit AES implementations -- code size & performance? |

Though I could live without actual source code right now, I'm trying to get a feel for both ROM requirements and data rate of 256-bit AES encryption on a PIC18F2620, as well as on a variety of dsPICs. Does anyone have any experience, first-hand or second-hand, in this?

I don't have first hand experience with AES on a PIC. I recenlty attended Microchip's dpPic 16 bit class. They talked about AES on the dsPic, and also said that there is a Microchip Library that you can buy that has all the AES code for sdPic. Not sure I understand why you have to buy a library that is a public algorithm? Probably because someone spent the time to optimize it for the dsPic.
They made it sound like now that the dsPic is out, you can finally do AES on a PIC. Maybe I read too much into it, and you can do AES on other PCS too. Either way, here is a link to the data sheet for the Microchip AES library.
