AI Technical Summary

Technical Problem

Existing technologies in smart security equipment, vehicle dashcams, and industrial edge computing terminals suffer from high data write latency, rapid flash memory wear, and a lack of critical data recognition capabilities, leading to data loss or file system corruption and failing to meet the high-reliability, high-persistence requirements of SD cards.

Method used

By introducing key data element attribute identifiers at the application layer and establishing an end-to-end key data identification and isolation path in the kernel I/O stack, key semantics are passed through reserved bits in the bio structure, enabling zero-copy, low-overhead key data scheduling.

Benefits of technology

It enables real-time disk writing of critical data, reduces SD card write latency, reduces flash memory wear, improves system reliability and throughput efficiency, and meets the persistence requirements of high reliability scenarios.

Abstract

The application aims to provide a key data instant landing method and device based on meta attribute identification. The key data meta attribute identification is introduced in an application layer, an end-to-end key data identification and isolation path is established in a kernel I / O stack, and key semantic is transmitted through a reserved bit in a bio structure body, so that zero-copy and low-overhead key data scheduling is realized.
