Cobham Gaisler AB provides IP cores and supporting development tools for embedded processors based on the SPARC architecture. We specialize in digital hardware design for both commercial and aerospace applications


Cobham Gaisler provides a complete framework for the development of processor-based SOC designs. The framework is centered around the LEON processor core and includes a large IP library, behavioural simulators, and related software development tools - all the necessary components to create high-quality and high-performance products. The design framework has been developed for dual use: for the development of critical space systems as well as cost-efficient consumer products. The stringent requirements for space systems gives a guarantee for quality and maturity of the framework, while requirements from cost-sensitive consumer products insures efficient and low-overhead implementations.

To support research and education, and to simplify evaluation, most of the design framework is provided freely in open-source and/or evaluation versions. This approach provides a large user base and valuable feedback from both the research community and commercial enterprise, allowing us to shorten the development cycle of new cores and tools.
