Key Highlights:

• Ubitium taped out the first silicon of its universal RISC-V processor on Samsung’s 8nm process.
• The chip aims to replace multiple specialized processors used in embedded systems.
• It runs Linux and RTOS together while handling AI inference and real-time signal processing.
• Volume production of the processor is expected by 2027.

The Ubitium universal processor has reached a key milestone. The German semiconductor startup has completed the tape-out of its first silicon on Samsung Foundry’s 8nm process.

The tape-out was finalized in December 2025 and announced this week. The chip introduces a universal RISC-V processor designed to replace the growing stack of specialized chips inside modern embedded systems.

The announcement signals a potential shift in how embedded computing systems are built. Instead of multiple processors handling different tasks, Ubitium aims to run those workloads on a single programmable architecture.

Why Embedded Computing Complexity Is Becoming a Problem

Embedded computing has expanded rapidly. Today, the market is estimated at $115 billion globally. However, as systems become more capable, they are also becoming more complex.

For example, early vehicles relied on a single processor. Modern vehicles, by contrast, often contain more than 200 processors. Each processor may come with its own software stack, toolchain, and supplier.

This complexity creates engineering challenges. Integrating hardware becomes harder. Software development becomes slower. Maintenance across long product lifecycles becomes expensive. The problem becomes even larger as AI workloads move to edge devices such as robots, drones, and industrial machines.

According to Ubitium’s CTO Martin Vorbach:

“This tape-out turns a long-held thesis into silicon. Embedded workloads have outgrown the architectures the industry relies on today. Consolidation isn’t optional anymore. It’s inevitable.”

The company argues that consolidation will become necessary as embedded systems grow more intelligent.

What Is the Ubitium Universal Processor?

The Ubitium universal processor builds on the open-source RISC-V architecture, which is already widely used in billions of chips worldwide.

However, the company extends RISC-V beyond the traditional CPU role. The processor combines multiple computing capabilities into one programmable platform.

The chip can run Linux and real-time operating systems simultaneously. At the same time, it can process radar and audio signals in real time while executing neural networks for AI inference.

Normally, these tasks require separate hardware components such as DSPs, GPUs, or AI accelerators. Ubitium’s architecture aims to handle them all within a single chip.

Importantly, the design maintains full compatibility with standard RISC-V software toolchains. This means developers can continue using familiar tools and frameworks.

How One Chip Could Replace Many Processors

Modern embedded systems often rely on a mix of processors. A typical design might include:

• A CPU for general computing
• A DSP for signal processing
• A GPU or accelerator for AI workloads

Each chip requires different programming tools and integration steps.

Ubitium’s approach focuses on reconfigurable computing. Its architecture includes a component called the Universal Processing Array, which can shift execution modes at runtime. This allows the processor to act as a CPU, DSP, GPU, or parallel accelerator depending on the workload. Crucially, the switch happens without the overhead normally associated with offloading tasks to external processors. The idea resembles the shift that occurred in software-defined radio, where programmable systems replaced fixed hardware blocks. If successful, this approach could reduce the number of chips needed in embedded systems.

Partnerships Behind the First Silicon

Ubitium worked with several technology partners to bring the chip to tape-out. Samsung Foundry manufactured the processor using its 8nm semiconductor process. Taejoong Song, vice president and head of Foundry Technology Planning at Samsung Electronics, said:

“The shift toward software-defined, reconfigurable compute is accelerating. Ubitium’s approach, one universal processor replacing multiple specialized chips, aligns with where we see embedded systems heading. We’re proud to manufacture their first silicon.”

Meanwhile, Siemens Digital Industries Software provided electronic design automation tools. Jean-Marie Brunet, Senior Vice President for Hardware Assisted Verification, noted that early validation helped the company test system behavior before silicon production.

ADTechnology also supported the project’s backend implementation and design closure process.

Target Applications for the Processor

The architecture targets several industries where embedded computing complexity is increasing.

Potential use cases include:

• Radar and multi-sensor signal processing
• Real-time audio and voice applications
• Computer vision systems
• Edge AI inference
• Automotive cockpit electronics
• Industrial human-machine interfaces

These environments often combine real-time data processing with AI workloads. That combination typically requires multiple specialized chips today. By consolidating these workloads onto a single processor, companies could reduce hardware complexity. This may also lower bill of materials costs and simplify long-term maintenance.

What Happens Next for the Chip

The first tape-out validates key elements of the processor’s architecture. This includes the Universal Processing Array and its LPDDR5 memory interface. The company plans a second tape-out later in 2026 as it refines the design. Volume production is currently targeted for 2027.

The founding team behind the project brings experience from companies such as Intel, Texas Instruments, Apple, and NVIDIA. CTO Martin Vorbach previously created the PACT XPP reconfigurable processor and holds more than 200 processor architecture patents.

As AI workloads move closer to devices, the need for simpler embedded architectures continues to grow.

Whether this architecture can replace dozens of chips in real products remains to be seen. However, the tape-out marks the first real silicon milestone for the Ubitium universal processor and its attempt to rethink how embedded systems are built.
