Remember when driving an LED just used a GPIO pin and you picked a resistor value to control the brightness. No longer.
Luckily the controlSUITE software can help you climb the learning curve. If you can standardize on one or two simple architectures (like the two described here) it can make the design even easier. However, make sure you know the key application requirements so your implementation is the best fit..

Blog Doing Math in FPGAs Tom Burke 15 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
