2007年全国大学生电子设计大赛，A题音频信号分析仪的全部源程序。 单片机为c8051f120，系统时钟倍频至96MHZ。 main.c是一个包含五级菜单的主函数。 FFT.C是进行fft变换，将时域信号变换成频域信号。 flash.c是读写片外flash存储器的程序,可以将分析结果保存,以备调用. z7290.c是周立功7290键盘芯片的驱动程序. FFT_xgjis.c是对变换后的频谱进行分析和运算. FFT_CodeTable.c是一个正弦表,在FFT的时候调用. LCD320240.c是320*240的液晶驱动程序,液晶的控制器是SED1335. 所有的.h文件提供了子函数的定义. 本程序用KEIL3 802版本编译通过，将所有的.C文件添加到工程中，并编译main.c 注意两点:1.器件选择c8051f120. 2.在target中将时钟设为96M.同时必须将Memory Model 改成large--XDATA.默认的是small. 因为本设计占用的资源是非常大的. Program Size: data=81.3 xdata=6811 code=43056

This tutorial presents an introduction to Altera’s Nios R II processor, which is a soft processor that can be in- stantiated on an Altera FPGA device. It describes the basic architecture of Nios II and its instruction set. The NiosII processor and its associated memory and peripheral components are easily instantiated by using Altera’s SOPCBuilder in conjuction with the Quartus R II software.

Abstract—In this paper, we propose transform-domain algorithms to effectively classify the characteristics of blocks and estimate the strength of the blocky effect. The transform-domain algorithms require much lower computational complexity and much less memory than the spatial ones. Along with the estimated blocky strength,
