The block provides three filter structures. The direct form systolic architecture provides a fully parallel implementation that makes efficient use of Intel and Xilinx DSP blocks. The direct form transposed architecture is a fully parallel implementation and is suitable for FPGA and ASIC applications. The partly serial systolic architecture provides a configurable serial implementation that makes efficient use of FPGA DSP blocks. For a filter implementation that matches multipliers, pipeline registers, and pre-adders to the DSP configuration of your FPGA vendor, specify your target device when you generate HDL code.

This table shows post-synthesis resource utilization for the HDL code generated from the Partly Serial Systolic FIR Filter Implementation example. The implementation is for a 32-tap FIR filter with 16-bit scalar input, 16-bit coefficients, and a serialization factor of 8 cycles between valid input samples. The synthesis targets a Xilinx Virtex-6 (XC6VLX240T-1FF1156) FPGA. The Global HDL reset type parameter is Synchronous and Minimize clock enables is selected.
This table shows post-synthesis resource utilization for the HDL code generated from the 32-tap filter in the Partly Serial Systolic FIR Filter Implementation example, with the Number of cycles parameter set to Inf. This configuration implements a fully-serial filter. The synthesis targets a Xilinx Virtex-6 (XC6VLX240T-1FF1156) FPGA. The Global HDL reset type parameter is Synchronous and Minimize clock enables is selected.
