Navigating the RISC-V landscape: unveiling the Embeetle IDE

3rd June 2024

Embeetle was founded by three engineers with unique insights into embedded software IDEs. The Embeetle team is committed to building a healthy MCU ecosystem, offering convenience to manufacturers and developers. The Embeetle IDE addresses one of the main challenges in adopting RISC-V technology: the development environment.

RISC-V, an open standard instruction set architecture (ISA), has been heralded as a revolutionary development in the world of microprocessor design. Born out of the University of California, Berkeley in 2010, RISC-V was created to address the complexities and escalating costs associated with proprietary ISAs.

At its core, RISC-V is defined by its simplicity and the flexibility it offers to hardware designers. As a Reduced Instruction Set Computer (RISC) ISA, it provides a small set of simple instructions, ensuring that the hardware implementation can be more straightforward than that of Complex Instruction Set Computers (CISC). The ISA is modular, meaning that base integer instructions are complemented by optional extensions for functions like floating-point arithmetic, atomic operations, and vector processing.

The defining feature of RISC-V is its open-source nature. Unlike proprietary ISAs such as ARM or x86, RISC-V can be used freely without the need for licensing fees or royalties. This openness is designed to foster innovation, reduce costs, and increase the speed of processor development across the industry.

Advantages of RISC-V

  • Cost-effectiveness: by eliminating licensing fees, RISC-V reduces the overall cost of developing a microprocessor
  • Customisability: companies can tailor the ISA to their specific needs, adding or omitting extensions based on the requirements of their applications
  • Community and support: an active community and the non-profit RISC-V Foundation support the development and implementation of the standard, promoting a collaborative approach to innovation

Challenges facing RISC-V

Despite its significant advantages, RISC-V faces several challenges:

  • Fragmentation: while modularity is a strength, it can lead to fragmentation. Different implementations might choose different sets of extensions, potentially complicating software development and system integration.
  • Software ecosystem: the success of an ISA heavily relies on its software ecosystem. RISC-V's ecosystem is still maturing, with fewer available software tools, libraries, and operating systems optimised for it compared to established ISAs like ARM or x86
  • Performance and efficiency: while RISC-V implementations are rapidly improving, achieving performance parity with highly optimised proprietary ISAs requires significant investment in design and fabrication technologies
  • Adoption by industry giants: convincing large companies to transition from their existing, well-supported ISAs to RISC-V involves overcoming inertia and substantial investment in new development tools and hardware

Embeetle IDE: simplifying RISC-V development

Embeetle’s IDE is not based on existing open-source IDEs like Eclipse, Visual Studio, or Netbeans but is designed as a completely new IDE tailored for embedded software development. As a result, the user experience with Embeetle IDE differs from other IDEs, offering a very intuitive experience.

Johan Cockx, CTO of Embeetle, stated: "The Embeetle team offers a clean and efficient IDE that is tailor-made for MCU development. We aim to lower development costs for both the users and the MCU manufacturers. The Embeetle IDE provides only the essential functionalities for embedded programming, making it very user-friendly."

Key features include:

  • A streamlined user interface that reduces complexity and focuses on code development
  • Full visibility of source files and libraries, which aids in understanding and debugging projects
  • A self-contained project model that encapsulates all dependencies within a single folder, enhancing portability and security
  • Support for a wide array of devices beyond RISC-V, including popular Arduino boards and STM32 microcontrollers

The EmbeetleIDE eliminates the usual hassles associated with setting up a development environment. It requires no installation; users can download and run the IDE from a USB drive, maintaining all settings and preferences in a single, portable directory. This approach not only simplifies the setup process but also enhances the overall security and integrity of development projects.

Embeetle IDE is free to use. It has recently added new features like Pin, Clock, and Peripheral Configurator, and the Embeetle team is continuously integrating different varieties of MCUs, opening more possibilities for the RISC-V community.
