模仿粒子运动的高质量随机数发生器，取粒子坐标得到随机数，附带测试结果图片-Mimic the particle motion of high-quality random number generator, taking the number of particle coordinates to be random, with test results picture

一款加解密SAM芯片的测试程序，包括AES，RSA，伪随机数模块！-An encryption and decryption SAM chip testing procedures, including AES, RSA, pseudo-random number generation module

环形缓冲区的C实现，包括测试用例。测试时根据随机数对缓冲区写和读。不过这个实现是静态的，没有用malloc，所以缓冲区大小是固定的256个字节。如果有问题欢迎联系我。kavin.zhuang@gmail.com-the C implementation of ring buffer, also include the simple but useful test program.
