Mi-V ecosystem aims to accelerate RISC-V adoption

Designed to enable open, lowest power, programmable RISC-V CPU products, Microsemi has announced the Mi-V ecosystem with industry leaders, to increase adoption of its RISC-V soft central processing unit (CPU) product family.

The company has also introduced Mi-V RV32IMA and additional FPGA-based soft CPU solutions that are suited for designs using RISC-V open instruction set architectures (ISAs).

Jim Aralis, chief technology officer and vice president of advanced development at Microsemi says: “Customers can now select RISC-V for their new designs knowing a tier one vendor committed to the success of this technology is providing all the necessary tools to confidently use RISC-V soft CPUs in their products.”

RISC-V, an ISA which is a standard open architecture under the governance of the RISC-V Foundation, offers benefits such as portability, as well as enabling the open source community to test and improve cores at a faster pace than closed ISAs. As the RISC-V IP core is not encrypted, it can be used to ensure trust and certifications not possible with closed architectures.

Microsemi’s Mi-V ecosystem 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.

“Micrium is pleased to join Microsemi’s Mi-V ecosystem with our . . .uC/OS-II real-time kernel, a full-featured embedded operating system,” said Jean Labrosse, co-founder and chief architect at Micrium. “As RISC-V continues to grow in popularity, we look forward to working closely with Microsemi to support accelerated adoption of its RISC-V soft CPU product offerings as well as the entire ecosystem’s RISC-V advancements.”

Microsemi’s Mi-V ecosystem, part of Microsemi’s Accelerate Ecosystem, contains design tools, including Microsemi’s SoftConsole Eclipse-based integrated development environment (IDE), the firmware catalog and Libero PolarFire system-on-chip (SoC). Operating systems include Express Logic’s ThreadX, Huawei LiteOS and Micrium µC/OS-II. Boards include the RTG4 development kit, IGLOO2 RISC-V board from Future Electronics, PolarFire Evaluation Kit and more. Debug dongles from Microsemi and Olimex, first-stage bootloaders and soft peripherals are also included. Example projects, drivers and firmware are all available on GitHub.

Deployment of soft CPUs implemented with the R11C-V ISA is automatic and delivered to the user’s desktop via Microsemi’s IP Catalog. No end user license agreements are needed to gain access to the soft CPUs. Using RISC-V soft CPUs within the Mi-V ecosystem is simple, easy and free.

Offering low power and an open architecture, Microsemi’s PolarFire, RTG4, SmartFusion2 and IGLOO2 FPGA-based RISC-V soft CPU cores are suitable for developing a variety of applications within the aerospace and defence, industrial and security markets. The Mi-V soft CPU cores make them particularly suitable for applications including guided munitions, IoT, secure communications and wireline bridging.
