Treck IPv4/v6 Dual Stack Datasheet

Product Information:

High performance embedded systems are the key technologies fueling innovative, high-growth applications of today’s fast-growing markets. These include digital wireless, broadband access, digital audio, high-resolution imaging and digital motor control. A key reason for embedding pre-designed functions is to reduce the time it takes to get complex systems to market while speeding their proliferation. The ability to rapidly design, test, debug and manufacture a device is crucial to the continued success of the electronics industry.

The embedded systems market is integrating computing and networking platforms capable of adapting to a range of specific applications. Whether you are a silicon manufacturer or OEM, you need a top of the line networking stack to reduce your capital expenditure risk and meet the stringent requirements of the market.

Treck’s networking protocols are specifically designed for embedded systems. We have created fast, efficient and reliable plug and play communication protocols so you can concentrate on your core competency and build designs that meet your “time to market” needs. Treck’s Treck IPv4/v6 dual stack is an ideal solution for embedded systems designers.

Modular Design

The Treck protocol suite can be configured to only include certain modules. When a module is not utilized, it is not just deactivated, it is removed entirely to save valuable storage space in the often limited capacity of an embedded device.

True Zero Copy

Treck products are zero copy from the application all the way through the driver, including TCP, this increases processing speed.

Written Specifically for Embedded Systems

Treck is written from the ground up, not derived from publicly available Unix stacks. Berkeley 4.4 compatibility, small size and high performance are key elements of our design.

Can Run With or Without RTOS

The stack is designed to easily integrate into an RTOS or Kernel. It can also run without an RTOS as its own task.


Some program variables never change their value at run-time, but instead are assigned a hardcoded value at compile-time.These variables could be put into ROM, if the code was written in such a way to identify them to the compiler. We add the “const” keyword in front of such variables to indicate they never change their value so the compiler can locate them in ROM instead of in RAM. This conserves RAM.

Treck IPv6 is a high performance nextgeneration protocol stack designed from the ground up specifically for embedded systems. To ensure product interoperability, Treck IPv6 features a dual-mode (IPv4/ IPv6) stack. This feature allows you to “switch” IPv6 functionality on or off depending on your needs.
