Lookup Tables
Blocks that model nonlinearity with lookup tables,
such as 1-D and 2-D Lookup Table
Blocks

that exploits quarter wave symmetry (HDL Coder) |
| Cosine HDL Optimized |
Implement fixed-point cosine wave by using lookup table
approach that exploits quarter wave symmetry optimized for HDL code
