DULLEA: Software SECDED ECC Memory Interceptor Map for 32-bit Bare-Metal Systems

A 2.4 KB text file containing a software-based Single-Error Correction, Double-Error Detection (SECDED) memory protection overlay. Authored by Jamie Davis and last updated on June 2, 2026, it is designed to safeguard RAM registers and state variables on 32-bit bare-metal architectures like ARM Cortex-M, ESP32, and STM32 against cosmic-ray bit flips and soft errors.

Use Cases

• Implementing runtime memory corruption detection and correction for critical variables based on the described Hamming(22,16) algorithm.
• Developing fault-tolerant firmware for aerospace or medical devices based on the described capability to flag uncorrectable double-bit errors.
• Optimizing safety-critical embedded applications with hard execution limits based on the described zero-dynamic-memory-overhead, freestanding C++ implementation.

Strengths

• Implements a specific Hamming(22,16) structural coding algorithm with an extended global parity block.
• Designed for zero dynamic memory allocation to meet hard execution cycle limits in safety-critical configurations.
• Targets specific 32-bit bare-metal architectures (ARM Cortex-M, ESP32, STM32) mentioned in the description.

Limitations

• The dataset is extremely small (2.4 KB), suggesting it is likely a code specification or document rather than a substantial data collection.
• Row count and column-level documentation are absent; the actual data structure and semantics must be inferred after download.
• The description is highly technical but does not detail the specific data format or provide sample records.
