rc6_avr
- AVR单片机的优化RC6 加密算法(速度快,其优化思想绝对值得学习) 在有128bytes RAM 的AVR单片机上执行 rc6 16/10/8(16 bit/10 rounds/8 bytes keys) * 对多数代码进行了 C 语言优化,对数据相关循环移位,模乘等用ASM优化 * 在4MHz无乘法器的AVR上得到平均 1172 Bytes/s的加解密速度。 * 编译器: AVR-G-AVR optimization RC6 encryption algorithm
CRC1632
- 本代码为查表法CRC16和CRC32校验的表生成和校验程序。使用此代码可以任意多项式生成CRC16和CRC32的程序。另有文件实现CRC16和CRC32的校验。 使用生成的表格,即可以在嵌入式中实现RAM和ROM区的校验。源程序在MSP430上实现,现整理成通用C版本。-the code look-up table method CYXLIC REDUNDANCY CRC checksum and the table generation and checking procedures. U
8052os
- /*看大家都在学操作系统,我也想学学。所以想用51写一个来玩玩,发现比较郁闷。 弄了几下,不想再弄了,51弄这个没啥意思。我用的89S52,除了速度慢,RAM资源 太少之外,其它都还过得去。弄了一点代码出来,放在那也没啥用,不如拿上来 给新手看看,一个任务调度的雏形是什么样子的~~~~~~~~~这些代码没有经过优化, 我只求实现任务切换的功能。 利用定时器2产生10mS的定时中断作为时钟节拍,任务切换时保存工作寄存器等操作 嵌入了汇编指令,因此Task_Switch.
PinYin_InputMethod_C51
- 用C51实现的拼音输入法,这是改写的网友 embuffalo、独步上载在www.21ic.com自由发布区的由张凯原作的51上的拼音输入法程序。 原作使用了一个二维数组用以查表,我认为这样比较的浪费空间,而且每个字表的索引地址要手工输入,效率不高。所以我用结构体将其改写了一下。就是大家现在看到的这个。 因为代码比较的大,共有6,000多汉字,这样就得要12,000 byte来存放GB内码,所以也是没办法的 :-( 编译结果约为3000h,因为大部分是索引表,代码优化几乎无效。

avr128usart
- 一般教科书上提供的UART收发的程序往往是一段采用轮循(Polling)方式完成收发的简单代码。但对于高速的AVR来讲,采用这种方式大大降低了MUC的效率。在使用AVR时,应根据芯片本身的特点(片内大容量数据器RAM,更适合采用高级语言编写系统程序),编写高效可靠的UART收发接口(低层)程序。下面是一个典型的USART的接口程序。-General textbook on the procedures provided by the UART transceivers often use a r
