Embedded & IoT

Intelligence where the system touches the physical world

Devices that ship once and run for years — firmware written against hard budgets for power, memory, and time.

Core Focus

Embedded engineering pillars

Four interconnected disciplines that turn raw microcontrollers into dependable edge appliances.

Deterministic Firmware

Bare-metal and real-time RTOS kernels that respect exact timing deadlines and memory boundaries.

Secure Device Lifecycle

Hardware root-of-trust, cryptographic secure boot, and dual-bank atomic A/B rollbacks in the field.

Edge Connectivity

Industrial bus protocols, cellular modems, BLE, and low-power mesh networks built for harsh interference.

Fleet Management

Zero-touch provisioning, fleet telemetry streaming, and remote diagnostic observability.

Edge Architecture

Co-designing hardware and low-level code

Edge computing and board–code co-design engineered as an integrated, synchronized discipline.

Edge Systems & Compute

Local signal processing

Edge filtering and inference execute on-device so the system responds instantly without cloud latency.

Resilient offline caching

Flash-backed queues and state machines prevent data loss during long-term network dropouts.

Edge gateway topology

Local hubs aggregate peripheral sensors, normalize schemas, and compress payload before uplink.

Hardware–Software Co-Design

Boundary co-design

Pinout layouts, clock trees, and DMA channels are mapped jointly by board and firmware engineers.

Bring-up verification

Hardware-in-the-loop (HIL)

Automated HIL test rigs simulate analog sensor inputs and fault states against live firmware builds.

Execution Limits

Engineered against worst-case constraints

Microcontroller specifications are engineered for extreme operating conditions — because edge hardware must operate unattended.

Power budget

Current draw is profile-measured across sleep, transmit, and active states under worst-case voltage drops.

Every microamp accounted for

Memory budget

Static allocation models prevent heap fragmentation, memory leaks, and stack overflows on microcontrollers.

Every byte planned

Real-time deadlines

Interrupt latency and deterministic context switching guarantees are validated with logic analyzers under peak load.

Hard worst-case latency

Field updates

Firmware updates are cryptographically signed, verified in staging buffers, and support automated fallback.

Atomic recovery built in

Longevity

Components, flash endurance ratings, and protocol standards are selected for multi-year unattended field life.

Years of unattended life

Edge Toolkit

Firmware runtimes & edge stack

Chosen strictly for memory safety, real-time determinism, and silicon resource efficiency.

Execution & RTOS

Bare-metal kernels, FreeRTOS, Zephyr, and Embedded Rust for memory-safe execution on constrained silicon.
