Architectural Layers & Regulatory Standards

Deterministic Microkernel Layer (seL4 Microkernel / FreeRTOS MPU Medical Profile): Formally verified microkernel enforcing priority preemption and bounded interrupt latency.
Memory Protection & Isolation Enclave (ARM TrustZone-M / RISC-V PMP (Physical Memory Protection)): Hardware-enforced MPU boundaries preventing non-critical logging tasks from corrupting vital algorithms.
Hardware-Accelerated Neural Inference (CMSIS-NN Vector Kernels / INT8 Quantized Tensor Arrays): Low-power vector NPU executing quantized 1D/2D CNNs for real-time electrophysiological wave analysis.
Clinical Decision & Dispatch Interface (IEC 60601-1-8 Audio/Visual Hazard Controller): Synchronous dispatch of high-priority alarms to bedside displays and central nurse consoles.

Key Metrics: < 100 µs (Worst-Case Interrupt Latency) | 100% (Formal Memory Safety Guarantee) | INT8 (Quantized Waveform Inference) | Class C (IEC 62304 Software Architecture)

秒が命を救う場所での予測可能な低遅延コンピューティング

Cloud-based medical algorithms are vulnerable to internet outages and packet jitter. SaMDCompute standardizes edge acceleration platforms that guarantee worst-case execution times for real-time hemodynamic alerting and automated drug delivery.

Core Engineering Areas
