📖 What is AkiraOS?
AkiraOS is a production-ready embedded operating system that enables secure, dynamic application execution on resource-constrained devices through WebAssembly.
Core Features
✅ Zero-Trust Execution - WASM sandboxing + capability-based access control
✅ Real-Time Performance - Zephyr RTOS with <60ns native call overhead
✅ OTA Updates - MCUboot secure firmware updates with rollback
✅ Multi-Platform - ESP32, nRF54, STM32, native simulation
✅ Modular Connectivity - WiFi, Bluetooth, USB, mesh (future)
✅ Rich SDK - Display, input, sensors, RF, storage, networking, and system APIs
Key Metrics
| Metric | Value |
|---|---|
| Native Call Overhead | ~60ns |
| WASM Load Time (100KB) | ~80ms |
| Concurrent Apps | 4 instances |
| Memory Per App | 64-128KB configurable |
| Boot Time | ~500ms (ESP32-S3) |
