Reliable Embedded Software, IoT & Edge AI
We build secure IoT firmware and deploy low-latency, on-device machine learning to constrained silicon platforms—with our deepest expertise across leading hardware ecosystems, including Renesas, NVIDIA, and Raspberry Pi.
Derived from Greek γνώμων (gnōmōn), literally meaning "one who knows or examines".
Like the gnomon—the pillar of a sundial that casts the shadow to reveal time and direction—we provide the architectural vision and technical clarity that guide hardware forward.
革新的な技術で「人を中心とした」スマートな社会を創造する
To make smart Human-Centric society enabled by innovative technologies.
Technology serves human capability. We build dependable, low-latency embedded intelligence and firmware designed to operate quietly, efficiently, and securely in human environments.
Core Focus Areas
Connected Device Firmware
Wireless connectivity firmware. Secure provisioning, OTA update mechanisms, and cloud connectivity.
TinyML & Edge Intelligence
Model optimization, int8 quantization, and efficient pipeline deployment for microcontrollers. Bringing real-time inference, vision processing, and anomaly detection directly to the edge.
Silicon-Level Firmware
Deep architectural specialization across Renesas RA, RZ, and RX families. End-to-end expertise in Renesas Flexible Software Package (FSP), e² studio, and production-ready custom BSPs.
Engineering in Practice
Featured R&D
Real-world engineering case studies showcasing hardware constraints and solutions.
Client and product names are withheld to protect confidentiality — all engagements are covered under NDA.
Embedded Vision & TinyML Memory Optimization
Designed memory-constrained embedded vision pipelines using the Cortex-M85 based Renesas EK-RA8P1. Resolved strict SRAM and Flash ceilings by engineering double-buffered zero-copy DMA capture pipelines alongside TFLM workspace allocations for high-efficiency image inference.
Secure Embedded AI & On-Device Vision Defense
Engineered next-generation firmware architecture with security as a core design principle. Implemented a secure Embedded Face Detection framework on Renesas silicon, applying STRIDE threat modeling and hardware root-of-trust boundaries to safeguard dynamic memory and proprietary model weights against physical and remote extraction.
Advanced Features R&D for Next-Gen Silicon
Executed multi-phase architecture research and development evaluating cutting-edge peripherals, DSP extensions, and Helium/NPU acceleration on RA8 Series microcontrollers. Delivered complete verification test suites, architectural whitepapers, and production-grade BSP modules for enterprise deployment.

Our Engineering Philosophy
Hardware-Aware Intelligence
We bridge the gap between heavy algorithms and constrained silicon. Whether migrating legacy codebases to modern Renesas MCUs or deploying real-time ML at the edge, we engineer code that strictly respects memory, thermal, and energy limits.
How We Engage
Whether it's a single deliverable or an ongoing engagement, we scope to match.
Initial Technical Review
Send us your project brief, hardware schematic, or MCU targets directly via email.
Scope & Architecture
We establish memory budgets, performance KPIs, deliverables, and milestone schedules.
Execution & Delivery
Clean, testable, fully-documented code delivered straight to your target repository, with extended support and maintenance available beyond delivery.
