Athos Silicon Selects DreamBig Semiconductor’s Chiplet Hub™ for its Safety-Critical mSoC™ Platform Designed Ground-up for Autonomy
SANTA CLARA, CA - Athos Silicon is thrilled to announce its partnership with DreamBig Semiconductor to power the next generation of autonomy, starting by minimizing data movements to reduce power consumption and smoothing data bottlenecks to maximize compute core utilization. As part of this collaboration, DreamBig's cutting-edge Chiplet Hub™ will be integrated into Athos Silicon's inaugural chip, code-named Polaris, the first realization of Athos' revolutionary multiple Systems on Chip™ (mSoC™) architecture setting a new benchmark for leading-performance, chiplet-based platforms, purpose-built for autonomy and the future of robotics, automotive, avionics and space applications.
The mSoC™ architecture empowers developers and system architects to tame today's unmanageably complex software stacks by transforming them into deterministic hardware architectures designed for safety certification, energy efficiency, and exceptional performance. At the center of the architecture is DreamBig's breakthrough chiplet, which delivers a generational leap in memory bandwidth and latency performance.
“The Chiplet Hub™ provides safety and integrates 3D HBM on top of a high-performance fabric base die, giving users centralized control of shared hardware resources across attached chiplets, a perfect fit for the mSoC vision,” said Steve Majors, SVP of Engineering at DreamBig.
The mSoC™ architecture is engineered for scalable and redundant compute, amplified by the Chiplet Hub's quad-sided UCIe die-to-die connectivity. This platform enables rapid iteration on combinations of different chiplets over the traditional time-consuming, capital-intense, ground-up ASIC design approach.
Francois Piednoel, CTO at Athos Silicon added, “At its core, the mSoC brings true safety through distributed voting. Each chiplet independently recalculates every decision. No master, no blind trust, just consensus hardened in silicon. Combined with DreamBig's Chiplet Hub, the architecture also allows the memory subsystem to scale as fast or faster than compute, fully leveraging the modular power of chiplet-based systems.”
Following Polaris, Athos Silicon is planning its second-generation chip, code-named NorthStar. NorthStar scales and repurposes validated Polaris building blocks for the highest level of safety and performance, bringing enterprise-cloud scale computing to the edge.
Stay tuned to Athos Silicon and DreamBig Semiconductor as their partnership kicks into high gear.
