SPARC or RISC-V? LEON or NOEL-V?
Ever wonder which microprocessor to use in your space system design?
Check out this white paper which discusses the differences between LEON/SPARC and NOEL-V/RISC-V architectures. The paper describes our past and ongoing component development and explains the rationale for some architectural design choices for future roadmap products. Included herein are trends in the Space industry that are driving key new features example application use-cases and tradeoffs from a software perspective of a legacy LEON/SPARC design vs. a new RISC-V architecture.

RISC-V Processor Model - NOEL-V
The NOEL-V is a synthesizable VHDL model of a processor that implements the open RISC-V architecture from the RISC-V International organization.
This is the first released model in the RISC-V product line of processors. Seven different configurations are now available for NOEL-V, ranging from a tiny 32-bit version to a 64-bit high performance version. NOEL-V complements the LEON line of processors.

Awarded ESA contract to develop RISC-V based System-on-Chip for space applications
We have been awarded a contract with the European Space Agency (ESA) to develop a fault- and radiation-tolerant system-on-chip. Funded by the Swedish National Space Agency, the project will improve performance and power efficiency in satellite and spacecraft applications by developing a 16-core, space-hardened microprocessor based on the open RISC-V instruction set architecture (ISA). The GR7xV processor is based on the NOEL-V processor IP core and will be designed into spaceborne controls and payload data management and processing systems to enable new kinds of observational, communication, navigational and scientific missions and services. These include advanced, flexible telecommunications satellite payloads, scientific and earth-observation payloads and robotics systems such as planetary exploration rovers.
