ecos RTOS 原理介绍和应用开发The design philosophy of eCos was to augment an open-source RTOS (which meant no per-unit royalties) with source-level con?guration tools that would enable embedded developers to scale their RTOS from hundreds of bytes to hundreds of kilobytes without needing to manu- ally change a line of source code.

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 algorithm is to count the dark colored pixels in the input image. This can be used in goods sorting like rice, paddy etc... in paddy or rice or other goods or products to sort out the bad or defect one we can use this algorithm. I had done this for my Masters Degree as a small part and now i am releasing for you. rajesh.f, Kanayakumari district, India. contact me: rajesh1983jan10@yahoo.com

This is a simple algorithm that downloads trading data from yahoo database. It is basically a large scale application of sqq.m which was originally submitted by Michael Boldin, link at acknowledgements. Some of the functionalities of the package: - User defined ticker list. - Function for downloading most recent SP500 composition in ticker list. - Control for bad data (e.g. a certain percentage of prices missing). - Choice of frequency of data (e.g. weekly prices). - Choice of starting and ending data. - Function for saving the whole data in a pre-formatted excel file together with a full reports on missing data.

The code performs a number (ITERS) of iterations of the Bailey s 6-step FFT algorithm (following the ideas in the CMU Task parallel suite). 1.- Generates an input signal vector (dgen) with size n=n1xn2 stored in row major order In this code the size of the input signal is NN=NxN (n=NN, n1=n2=N) 2.- Transpose (tpose) A to have it stored in column major order 3.- Perform independent FFTs on the rows (cffts) 4.- Scale each element of the resulting array by a factor of w[n]**(p*q) 5.- Transpose (tpose) to prepair it for the next step 6.- Perform independent FFTs on the rows (cffts) 7.- Transpose the resulting matrix The code requires nested Parallelism.
