For many years, I have used TI's DSPs for doing different kind of projects, Specialy I have used TMS320C31 and TMS320C7611 floating point, and TMS320C6201 fixed point DSP.
I accept that TI's DSPs are difficult, and time consuming to understand a learn, and I think that Analog Devices products are easier to learn. However, When it comes to system performance, cost, power consumption and factors like these, I think we should accept some difficulties and choose the better, more powerful DSP.
Recently, TI has worked a lot, on it's code composer studio. for example, The TMS320C6711 DSK, can be linked with matlab very very easily, you will not need to type even one line of TMS code, instead you can design your entire system using simulink it matlab. and so, you see how easy and fast is the work.
Code libraries: I do not know how complete, is the code library of analog devices. for TI, I know that they have even a simple, easy to learn, easy to configure operating system for their DSPs. they have implemented most of DSP functions, like FFT, Wavelets, ... for their DSPs ... and ...
Hum! Result:
Choose the one who is more powerful.
