SCI Semiconductor is a strong proponent of Open Source technology, believing that it both delivers both the opportunity to rapidly grow and thrive in a permissive ecosystem, and avoids the trap of maintaining proprietary commercial technologies.
SCI actively manages and maintains multiple repos on GitHub, including in partnership with Microsoft and Google in the management of the CHERIoT core. We also mirror development activities to our https://cheriot.org website and signal channels.
The CHERIoT project comprises several repositories:
The Capability Hardware Extension to RISC-V for IoT (CHERIoT) platform was originally developed at Microsoft and is now part of an effort spanning multiple companies. It builds on top of CHERI to provide a solid foundation for secure embedded devices. CHERI provides referential integrity (pointers cannot be forged), spatial memory safety (pointers carry bounds that cannot be extended), call gates, and so on.
CHERIoT extends this with a complete platform providing deterministic use-after-free protection, a lightweight compartment model, lexically-scoped delegation of objects across compartment calls, and many more benefits.
CHERIoT Capability replaces traditional pointer structures.
SCI are committed to open source and maintaining the permissiveness of the CHERIoT core, software and ecosystem. However in the development of our ICENI family of devices certain commercial differentiation has had to be evolved to meet the specific needs of the marketplace, especially for critical infrastructure, defense, and telecoms.
In order to continue to deliver ICENI and other solutions critical Intellectual Property has been evolved and registered, which we believe significantly enhances the solutions and delivers outstanding power and performance improvements.
Please contact SCI if you wish to discuss our extensive patent portfolio or trademarks.
ICENI devices are ideal for a wide array of applications in multiple markets.
However it is clear that that this type of device is not always best suited for high performance applications where a fully integrated system on chip (SoC) is required
SCI recommend SoC vendors thoroughly investigate the open source components of the CHERIoT ecosystem, but we are pleased to offer specific accelerators, system IP , and fully integrated processor systems that may support a faster time to market and enhanced software ecosystem support.
