A CREATING A TCP/IP
APPLICATION
This appendix is an overview of the theory behind the TCP/IP framework
provided by VisualDSP++. Examples 2 and 3 (on
respectively) of this book build upon the information presented in the fol-
lowing sections.
You will learn about the following concepts:
• TCP/IP framework
• VisualDSP++ Kernel (VDK) operating system
• Sockets API
TCP/IP Framework
The Ethernet Media Access Control (MAC) device of the ADSP-BF537
processor provides a 10/100-Mbits/s Ethernet interface between the
Media-Independent Interface (MII) and the processor's peripheral system.
You can create an embedded program, taking advantage of the Ethernet
MAC and using the TCP/IP stack support provided by VisualDSP++.
TCP/IP is a communication protocol that allows applications to transfer
data regardless of their underlying communication media. To implement
a TCP/IP application, several different elements are required. For an
EZ-KIT Lite system, the TCP/IP application framework consists of:
