D.SignT TCP/IP Stack for DSPs

TCP/IP Network Protocol Stack for Embedded DSP Systems

Network connectivity gains more and more importance in industrial applications. Data-base connectivity, browser frontends for configuration and setup, and remote maintainance are but a few features requiring a network interface. Such a network interface must however under no circumstances delay or block the DSP's main task: real-time signal processing.
Some applications might tolerate delays, e.g. biometric access control, but if the DSP is a part of the production environment, any violation of real-time constraints will inevitably cause system malfunction.
≫ ZeroConf/Auto-IP : automatic client configuration (IP address assignment)
≫ ARP : Address Resolution Protocol, resolves the IP address to a hardware MAC address. No user action is required. If an address is unknown, an ARP request is generated automatically.
≫ IP : Internet Protocol. All data transferred by DNS, DHCP, ICMP, UDP and TCP is automatically packed into IP packets.
≫ ICMP : Internet Control Message Protocol. The D.SignT.TCP/IP protocol stack responds to "ping" requests to test a connection
≫ UDP : User Datagram Protocol, provides a one-to-one or one-to-many connectionless data path. Data transmitted via UDP is not guaranteed to reach its destination. This protocol has very low overhead and is especially useful for transmitting non-critical data like audio and video streams, or any other realtime data where retransmissions cannot be tolerated.
≫ TCP : Transmission Control Protocol, provides reliable, connection-oriented, one-to-one connections. All data is acknowledged by the receiver and retransmitted automatically if required. This protocol should be used for critical data like software uploads, commands, etc.
≫ DHCP : Dynamic Host Configuration Protocol. This protocol has been developed to ease maintenance of a TCP/IP network. A DHCP server manages the allocation of IP addresses and provides additional network configuration data like gateways, DNS servers etc. The TCP/IP stack integrates the client functions required to obtain an IP address, DNS server, and gateway.
≫ DNS : Domain Name System. This protocol allows to use symbolic host names instead of numerical IP addresses. The TCP/IP stack integrates the client functions to query a DNS server to resolve a host name.
≫ FTP :
≫ HTTP : Hypertext Transfer Protocol, based on TCP. We do provide a HTTP server framework, which passes GET and POST parameters to a user-defined callback function, hence providing the required flexibility for dynamic data. The DSP can send static HTML pages and images as well as inserting the current value of variables, generate images from data acquisition buffers, etc. on demand.
≫ TELNET : Terminal-based communications for maintenance and updates
≫ SMTP : Simple Mail Transfer Protocol. Send and Email message or notification
≫ SNTP : Simple Network Time Protocol. Obtain the current time from a network/Internet server
