Well, I have a question, I have used ARM board for a long time and friends asked me a DSP board, I think my board is Devkit85000D board based on TI DM3730, which may includes DSP, so the question is what is the difference between ARM board and DSP board?
Besides, do you think AVR board is fast?

 

DSP board and ARM are different in that a DSP chip is specially designed for large volumes of multiplication and addition in a very short amount of time.
whats the purpose of this?
