Stack is made for small-footprint 32bit
systems
RTXC Quark TCP/IP uses a high-speed dataplane architecture to process TCP, IP and UDP packets rapidly with minimal "touching".
Available now from Nohau UK, RTXC Quark TCP/IP is heralded as a major new development in embedded networking software Developed by Nohau's US partner Quadros Systems, it is claimed to offer major advantages for small-footprint 32bit systems, operating at very fast speeds, requiring low power operation and reduced memory

Source code analysis takes holistic view
New approach to source code analysis enables location of complex cross-system bugs within a local build, ensuring defects are not propagated in the code stream.
The new software will initially be available for selected ARM-powered and ColdFire processors The new TCP/IP stack achieves its speed, power and memory advantages through a combination of a revolutionary stack architecture and a tight integration with the Quadros RTXC single stack real time operating system (RTOS) known as RTXC/ss.
RTXC products have been deployed worldwide in hundreds of millions of embedded systems, serving markets such as consumer electronics, communications, medical and industrial automation.

Environment accelerates real-time development
Visual design environment works with the RTXC Quadros RTOS to dramatically reduce development time for embedded systems.
The software also takes full advantage of the highly efficient, data-centric design of the RTXC/ss kernel.
The result is an RFC-compliant, embedded 10/100 Ethernet solution that directly addresses the memory and power-consumption requirements of 32bit replacements for 8 and 16bit microcontrollers.
RTXC/ss is a multithreaded real-time operating system designed for high responsiveness and low overhead.
The kernel employs a classic, time-proven design, in which all operations of the kernel and the application use a single memory stack.
This design offers incredibly fast operations, often measured in just tens of cycles.
With over 70 kernel services, RTXC/ss has the flexibility and richness to tackle the most complex real-time applications, but because of its single-stack design it has a very small ROM footprint and uses a minimal amount of RAM.
Together, RTXC Quark TCP/IP software and the RTXC/ss RTOS operate in less than 20Kbyte of ROM and require only minimal RAM per socket.
The ultrafast operation also reduces memory requirements because buffers are used quickly and then freed up.
Features include RFC-compliant protocols including IPv4, UDP, TCP, ARP, ICMP, DNS client, DCHP client, Berkeley Sockets v4.4 and Zero copy.
According to Kevin Pope, MD of Nohau UK: "The significant surge in new low cost 32bit microcontrollers has defined a clear need for software that can run efficiently in memory-constrained systems with limited or nonexistent external bus structures".
"RTXC Quark TCP/IP software aggressively addresses the small footprint challenge and offers the additional benefit of low power operation".
