一個簡單的SPI IP核,SPI Core Specifications 可以從說明文檔中找到!
The simple Serial Peripheral Interface core is an enhanced version of the Serial Peripheral Interface found on Motorola s M68HC11 family of CPUs. The Serial Peripheral Interface is a serial, synchronous communication protocol that requires a minimum of 3 wires.
FEATURES:
· Compatible with Motorola’s SPI specifications
· Enhanced M68HC11 Serial Peripheral Interface
· 4 entries deep read FIFO
· 4 entries deep write FIFO
· Interrupt generation after 1, 2, 3, or 4 transferred bytes
· 8 bit WISHBONE RevB.3 Classic interface
· Operates from a wide range of input clock frequencies
· Static synchronous design
· Fully synthesizable
This document describes the uIP TCP/IP stack. The uIP TCP/IP stack is an extremely small implementation of the TCP/IP protocol suite intended for embedded systems running low-end 8 or 16-bit microcon-trollers. The code size and RAM requirements of uIP is an order of magnitude smaller than other generic TCP/IP stacks today.

The intension of this code is to provide an example of attaching to the MUX layer with a custom
ethernet protocol. Though the NPT code is provided for handling alternate frames, it has not been tested.
Dropbear is an SSH 2 server, designed to be usable in small memory environments.
It supports:
* Main features of SSH 2 protocol
* Implements X11 forwarding, and authentication-agent forwarding
for OpenSSH clients
* Compatible with OpenSSH ~/.ssh/authorized_keys public key

Many programs today suffer from the fact that their users have to connect using IP addresses. This is impossible for dialup users, whose IPs change all the time, and painful for LAN users who don t know their IP addresses or whose addresses also change. In addition, many collaborative programs could benefit from offering friends lists, showing friends as online or offline, providing status information. This kind of functionality is hard to provide, requiring a dedicated Internet database and a new client - client protocol. But it is offered today through a system called AwareNet, which is offered free of charge and royalty
This book describes the following communications applications: Mail, Message Handler( MH), Transmission Controlprotocol/ Internet protocol(TCP/ IP), Basic Networking Utilities( BNU), and Asynchronous Terminal Emulation( ATE). It provides overviews, concepts, and procedures on receiving and sending mail and messages, transferring files( ftp command), printing files from and to a remote system, running commands on other systems, communicating between local and remote systems, and customizing the communications environment.
These two classes show an extremely simple example of java.net socket programming. They implement the Unix daytime protocol, an extremely simple protocol that consists entirely of the server sending its current local time and date to the client as an ASCII string. The server, to keep it very simple, does not use multiple threads. This code requires JDK 1.1 or later, but can easily be adapted to JDK 1.0.
This C++ code example provides a method for transferring objects or chunks of
data from one device to another via the Bluetooth OBEX protocol. These chunks
are typically files or other blocks of binary data. This example demonstrates
how to run OBEX on top of the Bluetooth RFCOMM protocol, but OBEX can also be
used with other transport media, such as IrDA and USB.
