- Abstract
This paper describes the design of a programmable microsystem for processing of digital audio effects implemented in an FPGA. The microsystem is designed using an specific purpose and reconfigurable processor, a bank of RAMs and a user graphic interface based on an LCD touch panel. The processor is designed using 15 audio effects based on delays, and dynamic and frequency domain processing. The effects are designed using Megafunctions and the FIR compiler of Quartus II, simulated in Simulink using DSP Builder, and configured using a user graphic interface. The programmable microsystem is implemented on the DE2-70 development board, and its operation is verified using an MP3 player and a speaker. Additionally, the microsystem allows the generation of effects with high fidelity using a maximum sample rate of 195.62 MSPS, and can be embedded into a SoC.
