Re: tms320
YES DEFINITLY YES the cheaper C2400 family is worth of replacing other cpus (arms ,51s pics ,etc). It is not as expensive as you might think .see digikey to have an idea (digikey is not cheap ).The C2000 family is powerful. It has a lot of peripherals and power consumption can be tuned.
what has happened is that MCU had gone up in performance and dsp had gone down in price and become stand alone controllers .Somewhere both had to meet .
And they did ! Now you can see any of these DSPs in the high end MCU hunting ground or the other way around .
other reason why people might not be yet using dsp for embedded standart aplications is the "AURA" of complexity of dsps And may be the cost of tools .
there are now lots of ports of commun embedded open applications to high end DSPs ( Os , tcp/ip stacks, web servers ,and even GUIs)
But i say yes........ "Is time to use dsp for more than to do DSP!"
