FIR Compiler

The Altera® FIR Compiler II MegaCore function generates finite impulse response (FIR) filters customized for Altera devices. You can use the IP Toolbench interface to implement a variety of filter architectures, including fully parallel, serial, or multibit serial distributed arithmetic and multicycle fixed/variable filters. The FIR Compiler II MegaCore function also includes a coefficient generator.

The FIR Compiler II MegaCore function speeds your design cycle by:

* Providing a fully integrated FIR filter development environment
* Generating the coefficients needed to design custom FIR filters
* Generating bit-accurate and clock-cycle-accurate FIR filter models in Verilog HDL, VHDL, and MATLAB
* Automatically generating the code required for the Quartus® II software to synthesize high-speed, area-efficient FIR filters of various architectures
* Creating Quartus II test vectors to test the FIR filter's impulse response
* Generating a VHDL testbench for all architectures


The FIR Compiler II MegaCore function generated by this compiler also:

* Supports a variety of distributed arithmetic and multiplier-based filter architectures up to 2,047 taps
* Generates MATLAB simulation models and testbench
* Generates a VHDL testbench for all architectures
* Is highly optimized for Altera device architectures
* Provides precision control of chip resource utilization * Utilizes logic cells, M512, M4K, M-RAM, MLAB, M9K, or M144K blocks for data storage
* Utilizes logic cells, M512, M4K, MLAB, or M9K blocks for coefficient storage
