Ubitium

Their processor is built on a Coarse-Grained Reconfigurable Architecture (CGRA) that unifies CPU-like out-of-order execution, DSP-style SIMD/MIMD loops and GPU-like SIMT threads within a single chip. At runtime, the processor reconfigures itself to match the workload, eliminating the data-transfer overhead and software complexity that comes with heterogeneous multi-chip designs. The chip is 100% RISC-V compatible, works with existing toolchains and software ecosystems, and can run Linux and RTOS simultaneously. In April 2026, Ubitium demonstrated the world's first CGRA to execute Linux without a host CPU.

The company completed its first silicon tape-out in December 2025 on Samsung Foundry's 8nm process, with a second tape-out targeted for later in 2026 and volume production in 2027. Target applications include radar signal processing, edge AI inference and industrial automation. Ubitium raised a $3.7 million seed round in November 2024, co-led by Runa Capital, Inflection and KBC Focus Fund.
