HDL-Optimized Filters and Transforms

Choose blocks or System objects to create HDL-optimized hardware system designs

These DSP HDL Toolbox™ blocks and System objects implement hardware-friendly architectures and support HDL code generation when used with HDL Coder™. These blocks and System objects also have high-throughput streaming interfaces, hardware control signals, and options to select different hardware implementations of their algorithms.
