RL-ARM User's Guide

RL-TCPnet

This chapter describes the RL-TCPnet component of the RL-ARM Library. RL-TCPnet is an implementation of the TCP/IP protocol stack. The stack aims at reducing the memory usage and the code size. This makes it suitable for devices with limited resources, such as embedded systems. The RL-TCPnet library is a ground-up implementation of software routines for the ARM7™, ARM9™, Cortex™-M1 and Cortex™-M3 architectures.

User applications are written using standard C constructs and compiled with the ARM® RealView® Compiler.

This chapter contains the following sections:
