CPU调度算法---模拟OS所使用的所有调度算法,包括创建一个kernel,PCB,队列，调度器等。-CPU Scheduler algorithms FCFS SJF Priority This code is a simulation of all the Scheduling algorithms an OS uses. I have tried creating a Kernel, PCB, Queue, Scheduler etc. what all an OS needs to run and execute a piece of code. Right now the code just displays the file given to in the input, If we modify the code so that it can interpret the meaning of the file then it can execute the file and can become a sub OS or VirtualMachine like JVM

An "improved" inductance / capacitance meter Actually, it works much the same as the originalIt differs from the original in that: A 16F628 PIC is used. This has internal comparator, which means the LM311 is no longer needed.Software calibration is used. The finished meter can be calibrated against "any" accurate capacitor within the range 100pF to about 10000pF -An "improved" inductance/capacitance meter Actually, it works much the same as the originalIt differs from the original in that: A 16F628 PIC is used.

利用51单片机控制ISD2560语音芯片实现语音的录放和存储，可自动调用，很实用的程序，绝对原创！-51 SCM control the use of voice chip ISD2560 voice playback and storage, can automatically call a very useful procedure, an absolute original!

就像在嵌入系统中使用C语言替代汇编一样,在嵌入系统中使用RTOS是大势所趋。原因主要是现在在大多数情况下编程效率比执行效率重要（单片机便宜嘛）。但纵观51的RTOS，keil c51 所带的RTX Full 太大（6k多），且需要外部ram，又无源代码，很多时候不实用。RTX Tiny虽然小（900多字节），但是任务没有优先级和中断管理，也无源代码，也不太实用。而ucosII虽有源代码，但是它太大，又需要外部ram，所有函数又必须是重入函数，用在51这类小片内RAM的单片机上有点勉强。于是，我借鉴ucosII和RTX Tiny编写了Small RTOS 51,虽然它为51系列编写，但是它还是比较容易移植到其它CPU上。 -err
