Download Using Faust for FPGA Programming In this paper we show the possibility of using FAUST (a programming language for function based block oriented programming) to create a fast audio processor in a single chip FPGA environment. The produced VHDL code is embedded in the on-chip processor system and utilizes the FPGA fabric for parallel processing. For the purpose of implementing and testing the code a complete System-On-Chip framework has been created. We use a Digilent board with a XILINX Virtex 2 Pro FPGA. The chip has a PowerPC 405 core and the framework uses the on chip peripheral bus to interface the core. The content of this paper presents a proof-of-concept implementation using a simple two pole IIR filter. The produced code is working, although more work has to be done for implementing complex arithmetic operations support.
Download FAUST Architectures Design and OSC Support FAUST [Functional Audio Stream] is a functional programming language specifically designed for real-time signal processing and synthesis. It consists in a compiler that translates a FAUST program into an equivalent C++ program, taking care of generating the most efficient code. The FAUST environment also includes various architecture files, providing the glue between the FAUST C++ output and the host audio and GUI environments. The combination of architecture files and FAUST output gives ready to run applications or plugins for various systems, which makes a single FAUST specification available on different platforms and environments without additional cost. This article presents the overall design of the architecture files and gives more details on the recent OSC architecture.
