Meaning I (or some other folks) and the programmers have to literally work side-by-side.

One project will probably require something of the caliber of a MSP430F6733. Whether this kind or a DSP, what is key is that we are able to use pre-coooked library routines. In my case for complex (I/Q) signal processing, FFT, non-linear filtering and so on. Sometimes legacy routines must be kept and in an FPGA that would require an IP block that can emulate the respective processor well enough. But what I see most is this: The respective client has in-house talent for writing code. They are familiar with a particular architecture, have a vast arsenal of re-usable code built up, and naturally they do not wish to give this up. If it's a dsPIC like last year, then that goes in there. If it's Atmel and MSP430 like this year, then that is used. Has to be, the customer is king.
