System-on-Chip Field Programmable Gate Arrays are excellent devices for high performance, low latency signal processing. Unfortunately, they are notoriously difficult to use, requiring significant hardware and software engineering expertise. To address these challenges, a development framework is created that utilizes graphical programming and automatic code generation; this framework reduces development time and reduces the need to be an expert in Field Programmable Gate Arrays. A sound effects processor and a real-time audio beamformer were created to showcase the development framework and serve as reference designs for other developers. The development framework, coupled with open source audio hardware, enables both experts and non-experts to rapidly prototype audio signal processing systems using System-on-Chip Field Programmable Gate Arrays.
