【正文】 HDL hardware description languages, as well as some periphery circuits. The musical performance can be done ， not only by keys but also with automatic type in the electronic piano. The article describes the design and implementation of the blocks, and describe VHDL language use FPGA technical at altera cyclone in the series of ep1c3t100n8 chip in programming. Electronic piano system design contains three main parts: keyboard control over the circuit, the circuit shown in the circuit. Fpga module of the design of system design the electronic ans are core contents of three modules. the anic bination of the circuit through the an played with automatic hand, the function. this product is characterized by low cost, performance, high precision, a development. The design of quartus ii software the language. the main storage design vhdl module and pressed the button control points, the frequency of the principle of the audio frequency design, make notes in written form to ram the memory socket, with a hardware means to achieve this effect.
