摘要
介绍了MP3播放器的工作原理,并介绍了基于现场可编程门阵列(FPGA)器件的设计思想和实现。根据系统要求,整个设计为6大模块,各模块采用VHDL或图形法设计。使用QuartusⅡ软件进行了编译和仿真,给出了仿真波形和仿真结果,基本达到了预期要求。由于FPGA具有高密度、可编程及有强大的EDA软件支持等特点,所以该设计具有功能强、灵活和可靠性高等特点,具有一定的实用价值。
This paper introduces the work principle of MP3 players, and introduces the design thoughts and realization based on FPGA. According to the demand of the system, the whole system consists of 6 modules, and each module adopts VHDL or the sketch method to design. We realize the edition and translation,imitation by the Quartus Ⅱ ,and prove that it is up to the expected desire. On high density,high speed and strong field programmable ability,you can see it has some advantages of strong function,modify convenient and high dependability. It has certainly practical nature and spreading value.
