Description
Sovereign Infrastructure Bare-Metal Microkernel Framework for Asymmetric Dual-Core Industrial Assets
Executive Architectural Overview
This repository contains a production-frozen, safety-critical Asymmetric Multiprocessing (AMP) bare-metal microkernel explicitly engineered for the Cortex-M4 Safety Sentinel Domain of dual-core heavy industrial power grid infrastructure [📋]. The system calculates real-time high-frequency grid traveling wave transients directly from Phasor Measurement Unit (PMU) telemetry [📋]. By eliminating dependency on fragile, external mechanical weather sensors, this deterministic processing engine safely unlocks 30% to 40% hidden thermal line transmission capacity on existing national high-voltage utility lines [📋].
Microarchitectural Invariants & Core Technical Safeguards
The codebase enforces strict, microsecond-deterministic execution boundaries designed to cross un-preemptible galvanic and silicon moats under intense electrical and cyber-warfare stress [📋]:
- Fixed-Point Transcendental Determinism (Math Integrity): Strips out 100% of fractional floating-point definitions (
float/double) to bypass non-deterministic hardware FPU processing lag and pipeline scheduling exceptions [ysD9J5]. Non-linear wave decay transformations are resolved branchlessly via integer-bound signed Q16.16 fractional format bit-shifts, utilizing a strict 4-iteration Taylor polynomial expansion to guarantee a uniform-time arithmetic execution envelope under all system loads [ysD9J5]. - Multi-Physics Lifecycle Decoupling (System Life Support): Hardwired hardware interrupt vector tables are relocated entirely away from flash bus boundaries to isolated, high-speed RAM_D3 space (
0x38000000) during boot [ysD9J5, 📋]. The safety calculations operate completely air-gapped from the high-overhead, non-deterministic SCADA networks and Modbus daemon loops sandboxed on the companion Cortex-M7 core—guaranteeing that local thermal loop defense arrays remain active even during an external network flood or a total host operating system freeze [📋]. - Padding-Hardened Structural Alignment (Memory Safety): Shared memory crossbar registers (
SRAM4) and internal workspace data structures are sorted strictly from largest data-type byte-width down to the smallest (64-bit → 32-bit → 16-bit → 8-bit) [ysD9J5]. Explicit manual padding blocks are injected to eliminate invisible compiler-generated memory voids, preventing random stack leakage onto the shared communication bus and satisfying MISRA-C:2012 / IPC Class 3 compliance invariants [ysD9J5, 0.1.1]. - Pointer-Driven Telemetry Stream Packing (Data Link Integrity): Telemetry serialization handlers reject index-increment loops, executing data movement via pure pointer memory address comparison constraints (
src_ptr < src_end) [ysD9J5, 0.1.1]. This approach packs variables contiguously up to terminal frame boundaries, pushing big-endian validation parity markers to the precise terminal edge bytes to eradicate data tearing or crossbar memory corruption [ysD9J5]. - Build-Profile Macro Abstraction (Continuous Integration Readiness): Virtualizes low-level physical registers and clock wait-states cleanly via preprocessor directives (
#ifdef USING_PRODUCTION_DRIVERS) [ysD9J5]. This permits automated continuous integration test suites to execute full-coverage memory and logic sweeps natively on standard x86/ARM64 desktop execution beds without encountering absolute memory pointer segmentation faults (SIGSEGV) [ysD9J5].
