Implementing High-Performance FIR Filters and FFTs in 28nm FPGAs

Finite impulse response (FIR) and fast Fourier transforms (FFTs) are two of the most common digital signal processing (DSP) functions implemented in FPGAs. In this webcast, you’ll learn how the FPGA industry’s first variable-precision DSP architecture, available in 28nm Altera® FPGAs, is optimized for FIR and FFT implementation. 

Watch this webcast to find out how variable-precision DSP block features can:

  • Efficiently implement FIR filters by incorporating a built-in pre-adder, co-efficient registers, and two levels of adder tree within the DSP block architecture
  • Implement FFTs with only half of the silicon resources required by competing FPGAs by incorporating unique features for complex multiplication across various bit widths

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
