Audio DSP to FPGA Compilation

Compilation Audio DSP vers FPGA

Abstract

The implementation of real-time audio Digital Signal Processing (DSP) applications on FPGA has been extensively studied in the past. Up to now, Audio IPs 1 were designed either "by hand" in VHDL or using predefined IPs in block synthesis environments. The advent of High Level Synthesis (HLS) allows for a real compilation flow from high-level audio DSP specifications down to FPGA bit-streams. This paper presents the principles and the implementation of the first "audio DSP compiler" targeting FPGAs. Our fully open-source system compiles audio DSP programs down to FPGA hardware and up to actual sound production. This compilation flow presents two important technological breakthroughs for audio programmers: achieving ultra-low latency real-time audio DSP (few micro-seconds) and the possibility of easily deploying systems with a large number of audio channels.
