介紹幾種cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/SB/SP/SQ microcontroller has 256-Kbyte expanded external code/data memory space and 64-Kbyte stack space. The new controller is also specially designed to execute C code efficiently. More importantly, the 8xC251SA/SB/SP/SQ maintains binary code compatibility with MCS 51 microcontrollers but at the same time allows the use of the powerful MCS 251 microcontroller instruction set, with many new 8, 16 and 32 bit instructions available. The 8xC251SA/SB/SP/SQ has 512 bytes or 1 Kbyte of on-chip data RAM options and is available in 16 kBytes and 8 kBytes of on-chip ROM/OTPROM or ROMless options.

This a naive implementation of BOOTP/TFTPBOOT, the protocols to use to bootstrap a computer through a TCP/IP network. The goal was to design a small footprint implementation to allow the code to be integrated into a monitor program stored in a ROM/FLASH, the footprint is about 7 kBytes for the test program. This code has not been yet tested in many environment. It should be seen at your starting point to integrate the network boot function to your board.

Title: File Transfer client and server Description: Send or recieve files of any size or type between you and a peer. Displays bytes sent or recieved, return values of send() and recv(), bitrate in kBytes/sec, and time remaining. SendFile and RecvFile functions can easily be added and used in your own code. I tested it ofcourse, a 73 mb self extracting rar archive from South Korea to Massachusetts at 96KB/s arrived fully operational.
