The Field Programmable Gate Array (FPGA) technology becomes widely used in industry. To prepare engineering students better for the need of the industry, the FPGA technology has been used in the academic filed as one cost-effective platform for prototyping digital systems in both teaching and research activities. This paper presents the usage of FPGA technology in the design of a digital audio recorder. It describes several building blocks including power amplifiers, analog-to-digital converter (ADC), digital-to-analog converter (DAC), SRAMs, LCD and the role of FPGA as a central controller. The main focus of this paper is to investigate the circuit design issues and Verilog hardware description language based FPGA design. The implementation of this digital audio FPGA project has been tested and the audio speech sound can be played back with the satisfying result.
