This project features a complete JPEG Hardware Compressor (standard Baseline DCT, JFIF header) with 2:1:1 subsampling, able to compress at a rate of up to 24 images per second (on XC2V1000-4 @ 40 MHz with resolution 352x288). Image resolution is not limited. It takes an RGB input (row-wise) and outputs to a memory the compressed JPEG image. Its quality is comparable to software solutions.

(1)测试外部数据RAM: 根据我们定义的逻辑,外部RAM在数据空间中定义在0x8000-0xFFFF,共32k字,占据RAM中的低32K存储空间。提供2种测试方法,采用一种方式即可。 硬件仿真模式下,将目标板上电。 第一种方法:采用用程序测试实验 程序所在目录ex1_RAMTest。 该程序执行的功能是对外部数据RAM区0x8000-0xFFFF,从0x8000开始写并且读数据0x5555 。如果正常则写读下一个地址,直到 。如果正常则所有的地址操作完毕后,核心板的指示灯会变亮。否则,如果写入数据后,读出的不正确,则指示灯会不断闪烁。 在CCS2000中的操作如下: 1. Progect->Open,打开该目录中的工程文件。 2. Progect->Rebuild All,编译链接 3. File->Program 4. Debug->Go Main 5. Debug->RUN(快捷键F5) 如果正常可以看到灯在熄灭约4秒后变亮。(说明:对整个数据RAM区的操作时间其实很短,为便于观察,本程序中加入了延时)。 打开View->Memory ,然后填入地址0x8000,然后在PAGE栏选择DATA。点击确定,即可显示0x8000地址开始的数据,用户会发现从这个地址开始往后的数据均为刚被写入的0x5555。

The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4- bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the W78E58B allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security

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
