µC/TCP-IP

μC/TCP-IP is a compact, reliable, high-performance TCP/IP protocol stack, optimized for embedded systems. Built from the ground up with Micrium quality, scalability and reliability, μC/TCP-IP enables the rapid configuration of required network options to minimize time-to-market.

μC/TCP-IP allows for adjustment of the memory footprint based upon design requirements. μC/TCP-IP can be configured to include only those network components necessary to the system. When a component is not used, it is not included in the build, saving valuable memory space.

The μC/TCP-IP design introduces a new concept: Large and small buffers. A large buffer is of the size required to transport a complete Ethernet frame. This is what other TCP/IP stacks do. But, in an embedded system, it is quite possible that the amount of information to transmit and receive does not require the use of a full Ethernet frame. In this case using buffers of the size of full Ethernet frames is a waste of RAM. μC/TCP-IP allows the designer to maximize the system performance by defining different quantities of small and large buffers.

μC/TCP-IP requires the presence of an RTOS for task scheduling and mutual exclusion. To meet this requirement, Micrium provides source code to allow network applications to readily accommodate μC/OS-II and μC/OS-III. Based on the component’s extensible Kernel interface, other Kernels can also be adapted to μC/TCP-IP.

μC/TCP-IP can be used on 16-, 32-, and even 64-bit CPUs or DSPs.
