Simplex Micro Joins Silicon Catalyst, Accelerating a New Era in CPU Architecture

Austin, Texas Nov 5, 2025 (Issuewire.com) Simplex Micro, Inc., a pioneer in deterministic scalar-vector-matrix RISC-V CPU IP, today announced its admission into Silicon Catalyst, the only accelerator focused on the Global Semiconductor Industry. This milestone marks a strategic step in Simplex Micros mission to redefine compute efficiency for edge AI and embedded systemsushering in a new era of deterministic CPU architecture.

Were honored to join Silicon Catalysts ecosystem of visionary semiconductor startups, said Dr. Thang Tran, Founder and CTO of Simplex Micro. We challenge the legacy of speculative execution by embracing deterministic scheduling and modular chiplet designdelivering fast, predictable performance at a fraction of the power and cost of legacy architectures.

Over the past two years, weve secured 19 patents, says Anelise Sacks, co-founder and executive chair of Simplex Micro. Our latest RTL benchmarks deliver 400 GFLOPS for 16-bit matrix multiplicationat least twice the performance of leading x86 and RISC-V competitors. This breakthrough unlocks dramatic power savings in data centers and brings real-time AI compute to the physical edge.

With 19 granted patents, Simplex Micro stands out as a Silicon Valley pioneer in deterministic CPU design. These innovations replace speculative, GPU-style execution with statically dispatched, time-aware controlensuring consistent throughput and latency tolerance. Phantom registers, time-aware scoreboarding, and memory load prediction eliminate stalls and latency. Thread synchronization and instruction scheduling ensure consistent execution across compute domains. Loop decoupling and vector buffering unlock high-throughput AI and ML performance. Together, they define a precise, efficient, and novel deterministic computing model.

Simplex Micro exemplifies the kind of architectural innovation we champion at Silicon Catalyst, said Raul Camposano, Partner at Silicon Catalyst. Their patented CPU architecture introduces a groundbreaking approach to deterministic scalar, vector, and matrix computing within the RISC-V ecosystemprecisely the kind of modular, high-performance design that will define the future of edge and embedded intelligence.

As a Silicon Catalyst member, Simplex Micro gains access to a world-class network of industry advisors, strategic partners, and in-kind support, including EDA tools, foundry access, and business development resources.

Designed for chiplet integration, Simplex Micros architecture features clean interfaces, deterministic thread sync, and minimal interconnect overhead; its CPU IP scales across vector and matrix accelerators, memory controllers, and domain-specific compute blocks. This positions Simplex as a core tile for edge AI, industrial, and embedded systems. By aligning with open interconnect standards and advanced packaging, Simplex enables OEMs and ASIC designers to build faster, more efficient systemswithout the complexity of speculative execution. In modular silicon, determinism isnt optionalits foundational.
