Microsemi's Mi-V Ecosystem Continues to Expand as New Member Antmicro Joins to Develop Mi-V RISC-V Processor Subsystems for PolarFire FPGAs

As part of their collaboration within the Mi-V ecosystem, Antmicro and Microsemi developed and tested software for Mi-V RISC-V processor subsystems. These were specially designed for Microsemi's lowest power, cost-optimized mid-range PolarFire® field programmable gate arrays (FPGAs), which are binary compatible to hardware, even before hardware is available. In addition to expanding Microsemi's Mi-V ecosystem, as well as the adoption of its PolarFire FPGAs, the collaboration improves the development experience and quality of Mi-V-based systems.

"Antmicro and its innovative Renode platform are excellent additions to Microsemi's Mi-V ecosystem and help us enhance our RISC-V design offerings for customers," said Venki Narayanan, senior director of system architecture and embedded solutions at Microsemi. "The Renode system brings rapid development and debug capabilities to our customers developing soft processors on our award-winning PolarFire FPGA. We look forward to further collaborations with the team at Antmicro, as well as the continued expansion of our ecosystem's overall portfolio of solutions."

Customers can design and debug a complete processor subsystem within Antmicro's virtual Renode environment on their desktop without actually needing target hardware. The resultant output is binary compatible to the processor running in the PolarFire FPGA. Antmicro's Renode technology makes it ideal for a variety of RISC-V-based applications within the aerospace and defense, security, communications, industrial, medical and internet of things (IoT) markets, including secure communications, flight controls, machine vision, image processing, wireless communications, building automation and factory automation.

"Renode has been designed to revolutionize the way we develop sophisticated embedded systems," said Michael Gielda, business development manager at Antmicro. "A business-friendly open source project coming from a software-driven embedded design house, Renode is the perfect match for both the Mi-V ecosystem, and the RISC-V technology in general. We are proud to be bringing advanced development tools for Microsemi's Mi-V to the wider developer community."

As part of Microsemi's Mi-V RISC-V ecosystem, Antmicro's Renode platform offers multiple connected virtual devices (multi-node) setups within the same simulated environment, bypassing the limitations associated with single device solutions like those from competitors. Using C#, a high productivity programming platform, and advanced abstraction layers, the solution boasts ease-of-development for customers without the hassle of C programming. In addition, it offers full visibility of the simulated platform enabling better insight and increased security, and is open source to allow for unlimited integrations, modifications and additions, as well as easy bundling and distribution to customers—particularly those leveraging Microsemi's SoftConsole.

• Easy model development with high-level programming environment
• Well-structured API, plugins and extensions model for easy integration
• Runtime reconfiguration and layers structure, ensuring sensitive information is isolated
• Continuous integration and improved development workflows
• Ease of implementation of test cases, allowing for greater test coverage

About RISC-V
RISC-V, an instruction set architecture (ISA) which is a standard open architecture under the governance of the RISC-V Foundation, offers numerous benefits, including portability as well as enabling the open source community to test and improve cores at a faster pace than closed ISAs. As the ISA is frozen, software which is written will always run on the RISC-V core, and since the RISC-V IP core is not encrypted, it can be used to ensure trust and certifications not possible with closed architectures.

About Microsemi's Mi-V Ecosystem
Microsemi's Mi-V ecosystem, part of Microsemi's Accelerate Ecosystem—a program designed to reduce time to market for end customers and time to revenue for ecosystem participants—brings together a number of industry leaders involved in the development of RISC-V to leverage their capabilities and streamline RISC-V designs for customers. Enabling third parties to access a growing platform for further RISC-V adoption and innovation, the Mi-V ecosystem provides firmware and hardware engineers a comprehensive ecosystem from a tier-one vendor.
