A study of an FPGA synthesizer

The mobile computing has been introduced to the general public and widely accepted at present. In the next stage, mobile computers enrich our lives and a lot of functions is required. High-performance synthesizers are eagerly anticipated to equip for mobile computing because it can help us and cheer up. Synthesizers are used for sound productions but then it requires enormous computational power. Therefore, each includes at least one digital signal processor but it is improper to mobiles. Here, this paper proposes a hardware synthesizer using a Field Programmable Gate Array (FPGA). The hardware synthesizer can bring high quality of the harmony and multiple simultaneous timbres. In addition, it can increase timbre of freedom and the analog circuits may be omitted from synthesizers.
