汇编语言求解八皇后问题

很经典的汇编程序,用DEBUG运行-classic compilation procedures, operating with DEBUG

经典的时钟读写程序，他包含对芯片的读操作和写操作，还特意说明一些注意事项-classic clock read and write procedures, the chip contains the read operation and write operation also specifically give some attention to matters

一个与一个低通滤波器结合可以用作简单、廉价的数/模转换器。其输出可用于驱动电压控制器件，或用于需要模/数转换器采样受控参数的反馈控制系统中。PWM常用于电机控制系统中。-A combination of a low-pass filter can be used as a simple, low-cost D/A converter. The output can be used to drive voltage control devices, or for the need for A/D converter sampling the controlled parameters of feedback control systems. PWM motor control commonly used in the system.

本题目的主要要求是要实现闹钟的功能内容：设计一个能够显示时分秒的数字时钟，时间显示为12小时制，除了显示分时秒外，并能实现上，下午。可以进行手动校时，定时（完成此题目时要有适当的设置，确定灯按钮，单，双灯作为报警显示），同时还应该能够清零。-the subject of the main demands is to achieve the alarm clock function : to design a display of accurate digital clock, the time displayed by the system for 12 hours, showing the time of seconds, and can achieve the afternoon. Can manually school, regular (completion of this topic have appropriate settings, to determine button lights alone, as the police showed two-lamp), but also should be able to reset.

0 到 9 和 0 到 99 的组装时，将显示此源代码。 再组装起来，使用 TASM，。 涡轮增压器装配。 做为 UMS 微处理器课程8086 微处理器的汇编语言源代码

使用TI TMS2407 实现SVPWM同步电机控制算法-TI TMS2407 realize the use of SVPWM control algorithm for synchronous motor

本例载波频率为20KHz，或载波周期为50μs。DSP晶振10MHz，内部4倍频，时钟频率为40MHz，计数周期为25ns。假设调制波频率由外部输入（1～50Hz），并转换成合适的格式（本例为Q4格式）。调制系数M为0～0.9。死区时间1.6μs。最小删除脉宽3μs。 主程序的工作是根据输入的调制波频率计算N、2N和M值。 -Example for the carrier frequency 20KHz, or carrier period is 50μs. DSP crystal 10MHz, internal 4 multiplier, the clock frequency of 40MHz, counting cycle 25ns. Assuming wave frequency modulation by external input (1 ~ 50Hz), and converted into an appropriate format (in this case for Q4 format). Modulation coefficient M is 0 ~ 0.9. Dead time 1.6μs. Delete the smallest pulse width 3μs. The work of the main program is based on input frequency modulation wave calculation of N, 2N and M values.

用于mann-kendall趋势分析，由于本人水平有限，只能做到这一步了，请凑活着用吧。-Mann-kendall for trend analysis, due to limited I can only do this step, please use your living together.
