See a demonstration of the lookup table optimization capability in Fixed-Point Designer™. This capability enables you to approximate a function or an existing block with an optimal lookup table. You can also compress the lookup tables in your design to reduce the RAM memory usage.
Designing an optimal lookup table involves various choices: fixed-point or floating-point data, size of the table, evenly spaced data or uneven spacing, and other algorithm settings such as the interpolation method. All of these decisions are automated using the Lookup Table Optimizer.
