This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM. The core acts as a slave WISHBONE device. The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file. Compression ratio is fixed for IMA-ADPCM, being 4:1.

RSA算法是第一个能同时用于加密和数字签名的算法，也易于理解和操作。 RSA是被研究得最广泛的公钥算法，从提出到现在已近二十年，经历了各种攻击的考验，逐渐为人们接受，普遍认为是目前最优秀的公钥方案之一。RSA的安全性依赖于大数的因子分解，但并没有从理论上证明破译RSA的难度与大数分解难度等价。即RSA的重大缺陷是无法从理论上把握它的保密性能如何，而且密码学界多数人士倾向于因子分解不是NPC问题。RSA的缺点主要有：A)产生密钥很麻烦，受到素数产生技术的限制，因而难以做到一次一密。B)分组长度太大，为保证安全性，n 至少也要 600 bits以上，使运算代价很高，尤其是速度较慢，较对称密码算法慢几个数量级；且随着大数分解技术的发展，这个长度还在增加，不利于数据格式的标准化。目前，SET(Secure Electronic Transaction)协议中要求CA采用2048比特长的密钥，其他实体使用1024比特的密钥。 这种算法1978年就出现了，它是第一个既能用于数据加密也能用于数字签名的算法。它易于理解和操作，也很流行。算法的名字以发明者的名字命名：Ron Rivest, AdiShamir 和Leonard Adleman。但RSA的安全性一直未能得到理论上的证明。

最长上升子序列 非常经典的问题。 给定的整数序列，请求出其最长上升子序列的长度。 有多个测试用例。每个测试用例由一个行整数组成，其中第一个是一个整数 n (1 ≤ n ≤ 10000)，表示给定序列的长度。然后是 n 个 32-bits 带符号整数表示序列中的元素。 输入直至没有数据或者遇到长度 n 是非正数为止。

To use the MSSP port to communicate with 3-wire devices, the bytes to be output must be aligned such that the LSB of the address is the 8th bit (LSB) of a byte to be output. From there, the bits should fill the byte from right to left consecutively.

A decade ago, I first wrote that people moved, and networks needed to adapt to the reality that people worked on the go. Of course, in those days, wireless LANs came with a trade-off. Yes, you could use them while moving, but you had to trade a great deal of throughput to get the mobility. Although it was possible to get bits anywhere, even while in motion, those bits came slower. As one of the network engineers I worked with put it, “We’ve installed switched gigabit Ethernet everywhere on campus, so I don’t understand why you’d want to go back to what is a 25-megabit hub.” He un- derestimated the allure of working on the go.
