ARM下 Implement matrix multiplication of 2 square matrices, with data read from an input file and printed both to the console and to an output file. • Assume a file with correct data (no garbage, characters, etc.). • you must check and provide appropriate execution for 2 extra cases, namely when the matrix size given is either “0” , or when the size is greater than the maximum handled of “5” . In these 2 cases you must implement the following behaviour: o If size = 0, then print a message “Size = 0 is unacceptable” and continue by reading the next size for the next 2 matrices (if not end of file). o If size >5, then print two messages: “Size is too big - unacceptable”. Then read and discard the next (size2 ) integers and continue by reading the next size for the next 2 matrices (if not end of file).

数字运算,判断一个数是否接近素数 A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample output yes yes no yes no

这个例子如果运行,将在仿真的PC窗口中的第1,2,3行显示一些信息后,在随机位置显示 1 ~ 5 .由于keil c51默认不支持重入函数,它的重入函数使用仿真的重入栈而不使用系统栈,而Small RTOS 51没有进行重入栈管理,所以在TaskA~TaskE虽然及其相似,但不能合并. 注意:(1)在KEIL C51 工程中,我已经把输出文件目录设在e:\temp中,您可以在Project->Options for Target "Target 1"的output页点击Select Folder for Objects...和Listing页点击Select Folder for Listing...改变. (2)编译时会有5个警告,其中一个是因为没有使用一个系统函数OSSendSignal引起,它可以忽略.另4个是禁止任务间变量覆盖分析引起,必须忽略.感谢网友John X. Liu,在这个例子中我使用了他编写的仿真(dllPc51Emu.dll),这个dll原来是为他移植的Ucos-ii for keil c51的例子编写. (3)Pc51Emu.dll在KEIL C51 V6.23 V7.00工作不正常.

这个例子是例子2的另一种写法(但任务数量不同),它使用了最高优先级任务作为显示任务,全局变量ShowChar作为参数.函数TaskB是优先级1~10的任务函数,因为没有使用局部变量,这些任务可以用一个函数. 注意:(1)在KEIL C51 工程中,我已经把输出文件目录设在e:\temp中,您可以在Project->Options for Target "Target 1"的output页点击Select Folder for Objects...和Listing页点击Select Folder for Listing...改变. 感谢网友John X.

2^x mod n = 1 acm竞赛题 Give a number n, find the minimum x that satisfies 2^x mod n = 1. Input One positive integer on each line, the value of n. output If the minimum x exists, print a line with 2^x mod n = 1. Print 2^? mod n = 1 otherwise. You should replace x and n with specific numbers. Sample Input 2 5 Sample output 2^? mod 2 = 1 2^4 mod 5 = 1

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.
