Speed and Area Optimization

Improvements through resource sharing and RAM mapping

For your target hardware, generate High-Level Synthesis code from a MATLAB® function that meets timing and area requirements by using speed and area optimizations. Area optimizations reduce resource usage of your design. Speed optimizations improve the timing of your design on the target hardware so that your design runs at higher frequencies by optimizing the critical path.
