Re: Pulse generator in VHDL?
Obviously the average fpga will outperform the average mcu. The thing is, carpenter hasn't specified anything like min/typical/max repetition rate, precision, output voltage, update rate (from software), yadda yadda ... So ye olde mcu might just do the trick, 100% depending on what the specs are. Barring awesome specs I'd suggest an MCU, and if higher performance is requiremed (get it? requirements.) an fpga can enter the picture. And if current generation fpga's don't do the trick the OP can always spend $$$ and roll his own ASIC. So I guess the point is: what are the requirements/specs?
Oh yeah, rise time, fall time? Fixed or configurable? Stuff like that.
