RISC-V

RISC-V (Reduced Instruction Set Computer - V) is an open-source Instruction Set Architecture (ISA) for processors that has rapidly grown in popularity across multiple industries, particularly in embedded systems, IoT devices, and beyond. Unlike proprietary ISAs, RISC-V provides a free, flexible, and extensible framework for hardware development, allowing for innovation without licensing fees or restrictions.

RISC-V Support in PikeOS and ELinOS

PikeOS and ELinOS fully support RISC-V architectures, ensuring seamless compatibility with the latest innovations in this open-source hardware ISA. RISC-V is increasingly adopted across microcontrollers, embedded systems, and edge computing due to its unique advantages:

Customer Benefits

Check

Open-Source: Transparency and Flexibility

RISC-V’s open ISA model reduces vendor lock-in, lowers development costs, and promotes full transparency. Its scalability makes it suitable for everything from low-power IoT nodes to complex Aerospace and Industrial Automation platforms.

Check

Highly customizable

RISC-V’s modular ISA combined with PikeOS’s partitioning enables highly tailored systems — from the instruction set to the OS configuration. Support for RISC-V extensions like "H" (Hypervisor mode) allows flexible deployment of multiple isolated guest OSes on a single hardware platform.

Check

Safety & Security

RISC-V supports features like memory isolation, PMP (Physical Memory Protection), and error detection. Together with PikeOS’s certified Safety and Security architecture, the platform is ideal for regulated domains like Aerospace, Automotive, and Industrial Automation.

Check

Future-Proof Technology

Driven by a global ecosystem of academia and industry, RISC-V evolves rapidly. Our products ensure early integration of RISC-V advancements, keeping your embedded systems aligned with the latest Security and performance features.

Check

Simplified Certification Path

When combined with PikeOS and ELinOS, RISC-V-based platforms benefit from modular, certifiable components. This reduces integration and verification complexity in domains requiring DO-178C, ISO 26262, or IEC 61508 certification.

Check

Unified Toolchain & Development Ecosystem

Through SYSGO’s CODEO IDE and integrated cross-compilation toolchains, RISC-V targets can be developed, debugged, and deployed using the same streamlined process as ARM or x86, accelerating developer onboarding and system bring-up.

Check

Optimized for Real-Time & Mixed-Criticality Systems

PikeOS supports deterministic scheduling and time-partitioning, critical for real-time RISC-V applications. This enables safe integration of real-time, Safety-critical, and non-critical workloads on a single SoC.

Check

Edge and AI/ML Readiness

Many new RISC-V cores target Edge AI, vector processing, and accelerators. With PikeOS and ELinOS support, these hardware capabilities can be integrated into secure, real-time workloads in IoT, Industrial, and Defense Edge deployments.

Check

Vendor Independence & Multi-Sourcing

RISC-V’s open standard allows you to choose from a growing number of chip vendors and silicon designs — avoiding proprietary lock-in and enabling long-term sourcing strategies and easier End-of-Life (EOL) planning.

About RISC-V

RISC-V International is the global non-profit home of the open standard RISC-V Instruction Set Architecture (ISA), related specifications, and stakeholder community

More than 3,100 RISC-V members across 70 countries contribute and collaborate to define RISC-V open specifications as well as convene and govern related technical, industry, domain, and special interest groups.

RISC-V combines a modular technical approach with an open, royalty-free ISA - meaning that anyone, anywhere can benefit from the IP contributed and produced by RISC-V. As a non-profit, RISC-V does not maintain any commercial interest in products or services. As an open standard, anyone may leverage RISC-V as a building block in their open or proprietary solutions and services.
