ecos RTOS 原理介紹和應用開發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年全國大學生電子設計大賽，A題音頻信號分析儀的全部源程序。 單片機為c8051f120，系統時鐘倍頻至96MHZ。 main.c是一個包含五級菜單的主函數。 FFT.C是進行fft變換，將時域信號變換成頻域信號。 flash.c是讀寫片外flash存儲器的程序,可以將分析結果保存,以備調用. z7290.c是周立功7290鍵盤芯片的驅動程序. FFT_xgjis.c是對變換后的頻譜進行分析和運算. FFT_CodeTable.c是一個正弦表,在FFT的時候調用. LCD320240.c是320*240的液晶驅動程序,液晶的控制器是SED1335. 所有的.h文件提供了子函數的定義. 本程序用KEIL3 802版本編譯通過，將所有的.C文件添加到工程中，并編譯main.c 注意兩點:1.器件選擇c8051f120. 2.在target中將時鐘設為96M.同時必須將Memory Model 改成large--XDATA.默認的是small. 因為本設計占用的資源是非常大的. 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.
