FIR filtering in ADSP CM408F

Sure, it can. You can write your own FIR filter (for example you can write a simple C loop to multiply filter coefficients by tap signals every time you get a new input sample). A much more efficient way is using CMSIS DSP library (search for arm_fir_f32 or arm_fir_fast_q15).

Of course, the processing power you need depends on the input sampling frequency, number of filter taps, etc.
