Re: Wich 16-bit MCU?

For your application, I suggest you to take a look at "a road less
traveled" -- DSP.

If you are not familiar with DSP, do not worry. A DSP is very much like
a MCU with additional features helpful in processing analog signals
digitally. Specifically, in addition to the usual registers, there is a
special very wide (large number of bits) accumulator. The instruction
set includes a "strange" one called MAC. MAC uses index to access
two words from two arrays, multiply the two words, add the result to
the special accumulator, and auto-increment the index. A good DSP does
MAC in one CPU cycle. Other than MAC, the instruction set looks just
like any MCU.

TI has a well-established line of DSPs called TMS320. It is mature and
yet still growing. Analog Devices has a DSP too.
