About RPU Microelectronics

RPU Microelectronics is an independent semiconductor IP provider specializing in autonomous, hardware-level event detection primitives for always-on systems.

We design and license the Reflexive Processing Unit (RPU) — an adaptive rate-of-change comparator with memory. Sitting directly behind a sensor ADC, the RPU continuously evaluates temporal signal dynamics against a floating, noise-tracking threshold. It autonomously decides whether incoming samples warrant waking downstream processors (CPUs, DSPs, NPUs) or classifiers, delivering a deterministic decision in two clock cycles with zero jitter and zero code in the execution path

Key Technical Highlights:
• Architecture: Discrete-time rate-of-change hardware primitive (~3,000 standard cells, 0.018 mm² in TSMC 65nm GP)
• Power Sweep (Standalone, TSMC 65nm worst-case corner): 56.8 µW at 1 MHz, 0.130 mW at 10 MHz, 0.859 mW at 100 MHz
• FPGA & System Validation: 99/99 board runs matched full-system simulation on 14 bitstreams integrated with a lowRISC Ibex RISC-V core
• Diagnostic Event Shell: Integrated hardware detection of sensor stalls, lost heartbeats, and frozen analog/digital values over a separate fault line
• Portability: Synthesizable SystemVerilog, validated in TSMC 65nm and SkyWater SKY130
• IP Status: Patent pending (PCT/IB2026/053070, priority TR 2025/012696)

Deliverables include delivered RTL cores, full-system FPGA evaluation kits on Nexys A7, acceptance verification scripts, and a bit-exact sensor calibration engine[cite: 6]. Free 30-day technical evaluation available under NDA.

THE GUARANTEE: Run our RTL on your own architecture, with your own data. If it does not outperform your current implementation — we do not invoice.
