Overview Provides a way to store very large collections of email addresses (100,000+ addresses) and efficiently check whether a specific address is contained in a collection. The collection can be created programmatically, or through a pluggable persistence mechanism. Functionality Maintains large collections of email addresses. Efficiently checks whether an address is in the collection or not.

tServer task executes functions at low priority (254). serverSend funtion is used to send a request to the tServer to execute a function at the tServer s priority. First tServer task executes the i() system call to print the summary of tShell task. Next an address exception is caused in tServer task by trying to execute a funtion at non-aligned word boundry. As a result SIGBUS signal is raised automatically. Signals (setjmp() and longjmp()) are used to allow the tServer task to recover gracefully from an address error exception. For more information about signals, please refer to sigLib manual pages.

Magenta Systems Internet Packet Monitoring Components are a set of Delphi components designed to capture and monitor internet packets using either raw sockets or the WinPcap device driver. Hardware permitting, ethernet packets may be captured and interpreted, and statistics maintained about the traffic. Uses of packet monitoring include totalling internet traffic by IP address and service, monitoring external or internal IP addresses and services accessed, network diagnostics, and many other applications. The component includes two demonstration applications, one that displays raw packets, the other that totals internet traffic. The components include various filters to reduce the number of packets that need to be processed, by allowing specific IP addresses to be ignored, LAN mask to ignore local traffic, and ignore non-IP traffic such as ARP.

xl2tpd a Layer 2 Tunneling Protocol (L2TP) daemon. It supports IPsec SA reference tracking, which enables the IPsec stacks to support multiple l2tp clients behind the same NAT router and multiple l2tp clients on the same internal IP address. It is a fork of "l2tpd". Release focus: Minor feature enhancements Changes: Support for passwordfd, a workaround for some Cisco routers, and extended logging.

This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec

This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It permits you to download new code to the device over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after reset. At startup, it waits for a few seconds to see if the downloader is trying to connect. If not, then the bootloader gives up control and jumps to your program. If the downloader is trying to connect, then the bootloader receives the new program over USB and writes it into flash.

P2P 之 UDP穿透NAT的原理與實現(xiàn)（附源代碼） 原創(chuàng)：shootingstars 參考：http://midcom-p2p.sourceforge.net/draft-ford-midcom-p2p-01.txt baidu 論壇上經(jīng)常有對P2P原理的討論，但是討論歸討論，很少有實質(zhì)的東西產(chǎn)生（源代碼）。呵呵，在這里我就用自己實現(xiàn)的一個源代碼來說明UDP穿越NAT的原理。 首先先介紹一些基本概念： NAT(Network address Translators)，網(wǎng)絡(luò)地址轉(zhuǎn)換：網(wǎng)絡(luò)地址轉(zhuǎn)換是在IP地址日益缺乏的情況下產(chǎn)生的，它的主要目的就是為了能夠地址重用。NAT分為兩大類，基本的NAT和NAPT(Network address/Port Translator)。 最開始NAT是運行在路由器上的一個功能模塊。 最先提出的是基本的NAT，它的產(chǎn)生基于如下事實：一個私有網(wǎng)絡(luò)（域）中的節(jié)點中只有很少的節(jié)點需要與外網(wǎng)連接（呵呵，這是在上世紀(jì)90年代中期提出的）。那么這個子網(wǎng)中其實只有少數(shù)的節(jié)點需要全球唯一的IP地址，其他的節(jié)點的IP地址應(yīng)該是可以重用的。 因此，基本的NAT實現(xiàn)的功能很簡單，在子網(wǎng)內(nèi)使用一個保留的IP子網(wǎng)段，這些IP對外是不可見的。子網(wǎng)內(nèi)只有少數(shù)一些IP地址可以對應(yīng)到真正全球唯一的IP地址。如果這些節(jié)點需要訪問外部網(wǎng)絡(luò)，那么基本NAT就負(fù)責(zé)將這個節(jié)點的子網(wǎng)內(nèi)IP轉(zhuǎn)化為

Avalon Interface Specification,The Avalon interface specification is designed to accommodate peripheral development for the system-on-a-programmable-chip (SOPC) environment. The specification provides peripheral designers with a basis for describing the address-based read/write interface found on master and slave peripherals, such as microprocessors, memory, UART, timer, etc.

雜湊法(Hashing)的搜尋與一般的搜尋法(searching)是不一樣的。在雜湊法中，鍵值(key value)或識別字(identifier)在記憶體的位址是經(jīng)由函數(shù)(function)轉(zhuǎn)換而得的。此種函數(shù)，一般稱之為雜湊函數(shù)(Hashing function)或鍵值對應(yīng)位址轉(zhuǎn)換(key to address transformation)。對於有限的儲存空間，能夠有效使用且在加入或刪除時也能快的完成，利用雜湊法是最適當(dāng)不過了。因為雜湊表搜尋在沒有碰撞(collision)及溢位(overflow)的情況下，只要一次就可擷取到。
