Boost the speed of sine calculations for processor

Posted: 02 May 2011     Print Version  Bookmark and Share

Keywords:sine calculation  hardware accelerators 

There are many ways to calculate a sine value for single-precision floating-point numbers, but one of the most powerful is to add hardware accelerators. That was our conclusion after exploring a number of approaches for providing a good, fast and efficient solution when a customer application required this type of sine calculation.

To determine which implementation works best for your application, first start by profiling your code base to find out which function needs some improvement. Then, because software is easier and quicker to change than hardware, check to see if soft ware changes will deliver the higher speed you need (sometimes they do). But if you still require more performance, then think about implementing parts of the algorithm in hardware. With hardware acceleration, you can easily outperform any microcontroller or DSP on the market.
