  • This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM.

    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算法是第一個能同時用于加密和數字簽名的算法

    RSA算法是第一個能同時用于加密和數字簽名的算法,也易于理解和操作。 RSA是被研究得最廣泛的公鑰算法,從提出到現在已近二十年,經歷了各種攻擊的考驗,逐漸為人們接受,普遍認為是目前最優秀的公鑰方案之一。RSA的安全性依賴于大數的因子分解,但并沒有從理論上證明破譯RSA的難度與大數分解難度等價。即RSA的重大缺陷是無法從理論上把握它的保密性能如何,而且密碼學界多數人士傾向于因子分解不是NPC問題。RSA的缺點主要有:A)產生密鑰很麻煩,受到素數產生技術的限制,因而難以做到一次一密。B)分組長度太大,為保證安全性,n 至少也要 600 BIts以上,使運算代價很高,尤其是速度較慢,較對稱密碼算法慢幾個數量級;且隨著大數分解技術的發展,這個長度還在增加,不利于數據格式的標準化。目前,SET(Secure Electronic Transaction)協議中要求CA采用2048比特長的密鑰,其他實體使用1024比特的密鑰。   這種算法1978年就出現了,它是第一個既能用于數據加密也能用于數字簽名的算法。它易于理解和操作,也很流行。算法的名字以發明者的名字命名:Ron Rivest, AdiShamir 和Leonard Adleman。但RSA的安全性一直未能得到理論上的證明。

  • 最長上升子序列 非常經典的問題。 給定的整數序列

    最長上升子序列 非常經典的問題。 給定的整數序列,請求出其最長上升子序列的長度。 有多個測試用例。每個測試用例由一個行整數組成,其中第一個是一個整數 n (1 ≤ n ≤ 10000),表示給定序列的長度。然后是 n 個 32-BIts 帶符號整數表示序列中的元素。 輸入直至沒有數據或者遇到長度 n 是非正數為止。

  • To use the MSSP port to communicate with 3-wire devices, the bytes to be output must be aligned

    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.

  • 802.11n A Survival Guide

    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.
