Semidynamics Wiki

Overview

Semidynamics is a Barcelona‑based European company providing fully customizable 64‑bit RISC‑V IP cores tailored for machine learning, AI, high‑performance computing (HPC), and data‑intensive workloads. Its signature value proposition lies in seamless integration of CPU, vector, and tensor units into a unified, scalable compute architecture.

History & Foundation

Founded in Barcelona in 2016 by semiconductor professionals with deep experience, Semidynamics began by designing custom RISC‑V cores for early clients, including a multi‑core RISC‑V processor for Esperanto Technologies. Over time, it evolved to offer licensed IP cores and configurator tools for customers to build highly specialized designs optimized for specific markets and applications.

Technology & Offerings

Semidynamics’ technology platform integrates several core innovations:

• Atrevido – A configurable, out‑of‑order 64‑bit RISC‑V CPU core focused on high throughput and flexible instruction support.

• Avispado – A simpler, in‑order 64‑bit RISC‑V core for low‑power and more predictable performance needs.

• Customizable Vector Unit – A wide SIMD unit (up to 2048 bits) designed to accelerate activation‑style computations.

• Tensor Unit – A specialized coherent unit optimized for matrix multiplication (e.g. deep learning inference tasks).

• “Gazzillion Misses™” Technology – A memory‑wall mitigation subsystem capable of tracking hundreds of in‑flight cache misses per core, dramatically reducing latency when accessing large or remote memory pools.

These technologies can be licensed individually or combined into an All‑In‑One AI Compute Platform, offering CPU + vector + tensor compute within one unified RISC‑V executable pipeline.

Software and Ecosystem

• Aliado SDK & ONNX Runtime Support – A development toolkit enabling deployment and optimization of AI models using open standards like ONNX, aligned with the RISC‑V ISA.

• Web‑based Configuration Tool – Enables customers to design and visualize their custom core configurations (including instructions, caches, memory interface, vector/tensor units) in real time and generate quotes for licensing.

Key Milestones

• Emerged from stealth in 2023 with a portfolio of customizable RISC‑V cores.

• Released the high‑width vector engine and Gazzillion misses capability in 2023.

• Launched the integrated Tensor Unit and the Cervell family of NPUs in early 2025, scaling up to hundreds of TOPS compute performance.

• Recognized by industry analysts for its All‑In‑One architecture unifying CPU, GPU‑like vector, and NPU‑like tensor acceleration.

Markets & Applications

• Edge and embedded AI devices, robotics, drones, smart sensors.

• HPC, large‑language model inference, generative AI workloads.

• Automotive, vision, industrial automation, and compute‑intensive instrumentation.

• Customers include European Processor Initiative collaborators and emerging chip companies seeking Processing‑in‑Memory or chiplet‑based GenAI hardware.

Business Model & Growth

• Private, venture‑backed company headquartered in Barcelona.

• Flexible licensing model: design customization, intellectual property licensing, and optional design‑services collaboration.

• Rapid team growth and active participation in European RISC‑V consortia and processor initiatives.

Vision & Mission

Semidynamics aims to democratize and accelerate AI computing via fully customizable, integrated RISC‑V processor IP. Its approach targets the elimination of architectural silos (CPU vs GPU vs NPU) and simplifies design complexity, thereby empowering customers to innovate faster, more efficiently, and with better control over performance, power, and programmability.
