Design Of Digital Audio System Based On FPGA

With the rapid development of microelectronics and computer technology, Electronic design automation (EDA) has become an indispensable tool for electronic design engineers. For designers, the traditional design methods are required to design circuit schematics, design printed circuit board .Then installation and testing, And the entire process is time-consuming. Moreover, the method used to design the circuit size is large and has low reliability. Semi-custom ASIC has a high degree of integration, It can make the hardware smaller in scale, increased reliability and low consumed Power.However, the design cycle is long, expensive and the risks are also great. The emergence of Programmable logic devices (PLD) in a certain carry out to fast, flexible design for Digital systems design engineers. The applications of PLD has a series of strong functions and high-speed, the flexibility of the modular system design. With the development of modern digital system, PLD in the integrated capacity, speed, field programmable design, the flexibility would not be able to satisfy the high-capacity, high-speed, high flexibility requirements. FPGA devices have the advantage of semi-custom gate array circuits, and programmable logic device characteristics of the user programmable combination. It can make the electronic products not only with a lot of gate circuit, with a high speed, miniaturization, Integrated and high reliability but also have the characteristics of user-programmable. Use FPGA design circuit can greatly shorten the product development cycle, reduce design costs and reduce the risks. FPGA is the latest generation of programmable logic device. It provides an effective system of large research and development approach for engineer. FPGA devices and circuits are being seen as a revolution in circuit design.FPGA software is another major advantage. There are all kinds of input FPGA software tools, simulation tools, layout design tools and Programmer and so on. Circuit designers can complete the circuit input, editing, optimization, simulation until the last chip production in a very short period of time. Use FPGA to design circuit,...
