Which DSP is more similar to C6455?

Alberto,

Are you looking for which C66x device is most similar to C6455 or something else. 

In what way are you wanting them to be similar?  Their peripheral sets or something specific?

I'd say that C6655 is the most similar DSP in the C66x (Keystone) family of devices.

Best Regards,

The problem is that we have bought an AD6M daughter board and in order to make it work my plan is to modify one of the examples which come with the daughter board. And this examples are working with 6416, 6713, 6701, 6203 and 6711 so I would like to modify the one which is the most similar one to the memory architecture of the 6455

Ok, you've posted this in a forum (C66x Multicore DSP Forum) that doesn't cover any of those devices.  I'll move this to an appropriate forum.

Best Regards,
Chad

Thank you

Is there any example of a C6455  working with a daughter card?

Alberto,

Instruction sets are most similar between the C6416 and the C6455. These are both fixed-point processors while all of the C67xx devices are floating-point processors. Use the C6416 examples as a starting point.

The memory location and startup will be different, but nothing major (depending on your point-of-view). Start with a "Hello, world" project on the C6455 to make sure you can build and execute a program, then start looking at migrating a more complicated project.

Try 6454. Its pin compatible with 6455.
