Tools and Techniques for Efficient High-Level System Design on FPGAs

In order for FPGAs to be successful outside traditional markets, tools which enable software programmers to achieve high levels of system performance while abstracting away the FPGA-specific details are needed. DSPB Builder Advanced (DSPBA) is one such tool. DSPBA provides model-based design environment using Matlab’s Simulink frontend that decouples the fully-algorithmic design description from the details of FPGA system generation. DSPBA offers several levels of debugging: from Simulink scopes to bit-accurate-simulation and silver reference models. It also offers the most comprehensive set of fixedpoint, floating-point and signal-processing IPs available today. The combination of 7 floating-point precisions, fused-datapath support, custom operator support and automated folding allows exploring the best tradeoffs between accuracy, size and throughput. The DSPBA backend protects users from the details of device-dependent operator mapping offering both efficiency and prompt support for new devices and features such as the Arria10 floating-point cores. The collection of features available in DSPBA allows both unexperienced and expert users to efficiently migrate performance-crucial systems to the FPGA architecture.
