OpenHW Group Announces RISC-V Based CORE-V MCU Development Kit for IoT Built with Open Source Hardware and Software


OTTAWA, Ontario–(BUSINESS WIRE)–OpenHW Group and its members today announced one of the industry’s most comprehensive open-source RISC-V development kits, including the OpenHW CORE-V microcontroller, CORE-V software development kit (SDK) with full Eclipse integrated development (IDE) and an open printed circuit board (PCB) design that supports Amazon Web Services (AWS) via AWS IoT ExpressLink. AWS IoT ExpressLink is a new service that powers a range of hardware modules and includes AWS validated software that securely connects devices to the cloud. The revolutionary RISC-V based CORE-V MCU DevKit enables software development for embedded, Internet of Things (IoT) and Artificial Intelligence (AI) based applications. The OpenHW Group is a global nonprofit organization driven by its members and individual contributors, where hardware and software designers collaborate to develop open source cores and associated IP tools and software. OpenHW Group and its members will demonstrate the OpenHW CORE-V MCU Development Kit for Cloud Connected IoT at Embedded World in Nuremberg, Germany, June 21-23, 2022.

The CORE-V MCU is based on the open-source CV32E40P embedded class processor, a small, efficient, open-source, 32-bit, in-order RISC-V core with a four-stage pipeline that implements the RV32IM[F]C RISC-V instruction extensions.

“The enormous potential of IoT applications requires new ways of thinking about design, and the open source community provides hardware, software and development tools to accelerate innovation,” said Rick O’Connor, President and CEO. from OpenHW Group. “It’s truly inspiring to see such a cohesive global collaborative engineering effort to develop open source building blocks that enable embedded microcontroller designs. »

During Embedded World week, OpenHW Group and its members will demonstrate the MCU CORE-V DevKit emulating a range of weather station sensors located throughout the showroom as well as various locations around the world. The demo, involving more than a dozen DevKits, will showcase the CORE-V MCU, the CORE-V SDK, and the interconnection of IoT sensors and the application to AWS, with local temperature readings on the CORE-V board. V MCU DevKit NexysA7. The demos will be on display at Embedded World at AWS booth #4-548, Digi-Key booth #4A-633, Embecosm booth #4-126, and the OpenHW Group booth at RISC-V Pavilion booth #1-550 as well than several places in the world.

The DevKit SDK, whose development was led by Ashling, contains an IDE, debugger, GCC compiler (provided by Embecosm), FreeRTOS real-time operating system, and AWS IoT ExpressLink connectivity, using WiFi radio based on Espressif’s RISC-V on AWS IoT ExpressLink. This project highlights the open source collaborative development of the industrial-grade CORE-V processor IP with supporting hardware and software by a wide range of members within the OpenHW community.

The growing OpenHW ecosystem has come together to deliver the innovative CORE-V DevKit for IoT developers:

  • CORE-V microcontroller is made by GlobalFoundries proprietary 22FDX® process technology platform that is well suited for the efficient single-chip integration of digital and analog signals, delivering cost-effective performance for connected, low-power embedded applications.

  • The design and verification of the CV32E40P processor, the heart of the CORE-V MCU, involved key contributions from Imperas, Siemens EDA, SiLabs and many others, building on the original ETHZ design. The CV32E40P core is based on the RI5CY core of the PULP (Parallel Ultra Low Power) platform, originally developed at the Integrated Systems (IIS) Laboratory of ETHZ and the Energy Efficient Embedded Systems (EEES) group of the University of Bologna. Digital integration and back-end design of the CORE-V microcontroller were handled by QuickLogic and CMC Microsystems, respectively.

  • The CORE-V microcontroller includes QuickLogic’s eFPGA, designed to accelerate AI/machine learning (ML) and other compute-intensive workloads from the CV32E40P processor.

  • Embecosm leads the OpenHW SW working group projects, including GCC compiler tools for CORE-V and MCU cores, while Ashling led the development of the CORE-V SDK based on the Eclipse IDE, OpenOCD for the debugging and sample programs.

  • Imperas posted riscvOVPsimCOREV as a free simulator for the CORE-V MCU, based on the Imperas RISC-V reference models used in CV32E40P verification, as a starting point for software development tasks.

  • The design of the CORE-V MCU DevKit PCB board integrating the CORE-V MCU and expansion board for the demonstration was handled by AWS, using a powered AWS IoT ExpressLink for secure cloud connectivity.

  • Espressif Systems, a leading provider of IoT connectivity solutions, provided the AWS IoT ExpressLink modules for the CORE-V DevKit PCB to deliver AWS IoT connectivity.

  • Data visualization for the demo is provided by Amazon Managed Grafana.

  • Manufacturing and shipping of the CORE-V MCU DevKit Early Access Campaign is coordinated by GroupGets. Quantities of the Early Access CORE-V MCU DevKit are limited and can be reserved here.
