Baya Systems Collaborates with Tenstorrent on Subsystem for TT-Ascalon Processors

Santa Clara, Calif. – September 25, 2025 — Baya Systems, developer of a software-driven, chiplet-ready fabric IP for scalable AI and high-performance computing, today announced: successful interoperability between Baya’s WeaveIP fabric and Tenstorrent’s TT- Ascalon processor portfolio and becoming one of the first members of Tenstorrent’s Open Chiplet Atlas (OCA).

Both companies are working on leveraging Baya’s fabric interoperability within OCA. Together, these milestones underscore their shared vision and commitment to enabling flexible, scalable, and customizable compute systems designed for the next generation of AI and other high-performance applications.

By integrating Baya’s chiplet-ready interconnect IP with Tenstorrent’s RISC-V-based Ascalon cores, system architects can now design and deploy compute platforms that are optimized end-to-end, from core to chiplet to system level. The collaboration brings to life a common vision: agile, software-driven development, optimization, and deployment of state-of-the-art systems.

Tenstorrent and Baya have jointly published a white paper with results that illustrate the performance, configurability, and scalability of this combined scalable compute solution. Building on the white paper on AI fabrics that the companies published in June, the two companies demonstrate how the WeaveIP fabric extends its technical leadership and versatility. Ascalon cores deliver best-in-class performance, both peak and per watt, while Baya’s WeaveIP fabric enables a data-driven system optimization to meet customer needs and dynamically adapt to Tenstorrent’s application requirements, ensuring future-proof scalability. The interoperability demos highlight how customers can design customized compute systems with faster time-to-market and reduced risk.
“We believe in a chiplet future, and interoperability across ecosystems is the only way to get there,” said Keith Witek, COO of Tenstorrent. “Baya’s WeaveIP is an elegant fabric that connects our market beating Ascalon processors in powerful and flexible ways. This is exactly the kind of collaboration that will accelerate innovation in AI and beyond.”

Tenstorrent is a leader in driving the RISC-V and AI processing ecosystems and has collaborated with Baya Systems on enabling designers to rapidly innovate and bring ground-breaking silicon platforms to market.

“Tenstorrent is redefining processor architectures for the AI age, and Baya is redefining system interconnects and system design paradigms. Together, we are enabling customers to weave scalable compute systems from proven, interoperable building blocks,” said Dr. Sailesh Kumar, CEO of Baya Systems. “This is a major step toward our mission of democratizing hyper-efficient, data-centric SoC and multi-chiplet design.”

As part of the collaboration, Baya Systems will support Tenstorrent’s Open Chiplet Atlas (OCA) ecosystem, ensuring seamless interoperability for customers adopting heterogeneous chiplet solutions. Baya’s WeaverPro design platform was built to help system designers analyze workloads at speed, partition and organize intelligent compute systems that scale across entire compute platforms, from SOCs through chiplets and beyond, while WeaveIP has been designed from the ground up to be chiplet-ready. Together, they provide a foundation for interoperable, scalable, and future-proof multi-die systems. This joint work paves the way for a broader ecosystem of co-optimized IP and compute chiplets, giving system developers more choice and control in crafting differentiated platforms.
