I have experience with selecting low end PICs, but haven't had to select a controller for DSP before. Initially I thought about the dsPIC line, but the only reason for this because I am comfortable with the microchip line.
So, what options do I have to select from? How can I decide what is best for me? Are there in general differences between lines? Example, the MSP430 line is good for very low power, are there any similar type of things for the DSP lines?
For my specific project I am going to have 3 sets of SPI from ADCs that are 24bit at about 400KHz, but I am find with broad description on how to find the proper platform.

If I was asked to look at DSP products, I would look at the architecture. The hardware architectures for DSP processors are more varied than for general purpose processors.
Then, looking at the algorithms that need to be coded, I would select a DSP architecture that is easier to use to implement the algorithms.
