Revenue model

1. RISC-V IP Licensing: Semidynamics licenses its RISC-V processor IP cores (CPU cores, vector units, tensor units, NPUs) to semiconductor companies and system-on-chip designers. Customers can license IP blocks such as the Cervell NPU, Atrevido CPU, and All-In-One solutions for integration into custom silicon.
2. Full-Stack AI Systems (Silicon to Rack): Following the February 2026 announcement, Semidynamics expanded into full-stack AI infrastructure, selling vertically integrated products spanning chips, boards, and rack-level systems for AI inference in next-generation data centers. Revenue from hardware product sales.
3. Software Development Tools: The Aliado SDK, Inferencing Tools, and ONNX Runtime integration are provided as part of the IP licensing or as standalone software tools for AI application deployment on Semidynamics hardware.

Core offering

Semidynamics designs and licenses high-bandwidth RISC-V processor IP cores — including the Cervell NPU, Atrevido out-of-order CPU, Vector Units, and Tensor Units — built around a proprietary memory-centric All-In-One architecture with Gazzillion Misses technology that addresses the memory bandwidth bottleneck in AI workloads. The company has expanded from IP licensing into full-stack AI infrastructure, selling 3nm AI inference silicon, boards, and terabyte-scale AI Inference Unit (AIPU) rack systems for next-generation AI data centers.

Product overview

Semidynamics offers a unified platform for memory-centric AI inference, combining configurable RISC-V IP cores (Cervell NPU, Atrevido CPU) with specialized processing units (Vector Unit, Tensor Unit) and proprietary memory technology (Gazzillion Misses). The company has expanded into full-stack AI infrastructure delivering chips, boards, and rack-level systems. Software enablement comes through the Aliado SDK suite (IDE, Toolchain, Kernel Library, Emulator) with ONNX Runtime integration, plus a Model Zoo of pre-optimized AI models. The architecture is designed for terabyte-scale AI inference, optimizing memory bandwidth rather than compute alone.

Partnerships

Six partnerships are on record, tiered flagship and core.

• SiPearlflagshipStrategic or Co-development Partner · 7 May 2026Semidynamics and SiPearl formed a strategic partnership to develop a European rack-scale AI compute platform for large-scale AI inference in the cloud. The platform combines SiPearl's Arm-based CPU (Rhea2, based on Arm Neoverse V2) with Semidynamics' RISC-V-based GPU/AI inference ASIC in an OCP-aligned rack design. Phase two will involve chiplet-level integrations via UCIe interconnect. Both companies will coordinate marketing, sales, and joint tender responses targeting European AI Factory and Giga Factory procurement programs. Manufacturing partners will adopt the reference architecture to produce complete rack systems.
• ONNX Runtime (Microsoft ecosystem)coreTechnology or Integration · 11 March 2025Semidynamics integrated support for its hardware into the ONNX Runtime environment, enabling seamless deployment of AI models on Semidynamics RISC-V processors. ONNX Runtime is an open standard for AI models originally developed by Microsoft, and most major AI frameworks support ONNX format. HuggingFace provides models in ONNX format enabling near-universal model compatibility without model compilation steps.
• Baya SystemscoreTechnology or Integration · 26 February 2025Baya Systems, a system IP technology company specializing in NoC (Network-on-Chip), partnered with Semidynamics to accelerate RISC-V SoC development for AI, ML, and HPC applications. The collaboration optimizes data movement within Semidynamics' AI processor designs, enhancing the efficiency of next-generation platforms. Baya Systems' WeaveIP NoC technology is integrated with Semidynamics' RISC-V processor IP for high-density AI compute environments.

Broad incumbents

• Graphcore: Graphcore develops Intelligence Processing Units (IPUs) for AI training and inference. Comparable as an AI accelerator hardware company with full-stack systems targeting data center AI workloads, though using proprietary IPU architecture rather than RISC-V-based design.
• NVIDIA: NVIDIA dominates AI compute with its GPU and Grace Hopper/Blackwell platforms. Semidynamics' Cervell NPU and full-stack AI inference systems target the same AI inference workloads as NVIDIA's data center accelerators, but as an emerging European alternative rather than a direct competitor at scale.
• Cerebras Systems: Cerebras builds wafer-scale AI compute systems for training and inference in data centers. Comparable in offering full-stack AI inference hardware systems rather than IP-only, though targeting much larger training workloads via wafer-scale integration versus Semidynamics' RISC-V-based approach.

Direct peers

• SiFive: SiFive is the leading commercial provider of RISC-V processor IP cores, licensing CPU cores to semiconductor companies worldwide. Highly comparable to Semidynamics' RISC-V IP core licensing business (Atrevido, Avispado), though SiFive is significantly larger and more established across general-purpose compute rather than AI-specific inference.
• Tenstorrent: Tenstorrent develops RISC-V-based AI accelerators and full-stack AI compute systems for data centers. Direct competitor in RISC-V AI inference silicon with overlapping customer targets in AI data center deployment, though Tenstorrent is at significantly later stage with Jim Keller-led design team.
• Ventana Micro Systems: Ventana designs high-performance RISC-V CPU cores for data center and cloud applications. Comparable RISC-V IP core business targeting data center workloads, though focused on CPU-only rather than AI-specific accelerators like Semidynamics' Cervell NPU.
• Esperanto Technologies: Esperanto develops RISC-V-based AI inference accelerators with thousands of cores per chip for high-performance inference. Directly comparable as a RISC-V AI inference hardware company targeting similar large-model workloads, though Esperanto focuses on monolithic massively-multicore designs versus Semidynamics' unified CPU+vector+tensor architecture.
• Imagination Technologies: Imagination Technologies licenses processor IP cores including CPU, GPU, and NPU IP to semiconductor companies. Comparable IP licensing model with neural network accelerator offerings (IMG NNA), though primarily serves mobile/embedded rather than the data center AI inference focus of Semidynamics.
• SiPearl: SiPearl designs Arm-based HPC processors for European exascale supercomputers and is Semidynamics' strategic partner for joint rack-scale AI compute platforms. Both are European processor companies targeting sovereign computing procurement, though SiPearl uses Arm Neoverse V2 versus Semidynamics' RISC-V.

Emerging players

• Hailo: Hailo develops edge AI inference processors targeting computer vision and generative AI at the edge. Comparable AI inference silicon business with Cervell NPU's edge configuration (8 TOPS INT8 compact edge tier), though Hailo is edge-focused rather than data center scale.
