In the past two years, a wide variety of on-board DVRs (vehicle-mounted DVRs) have appeared on the market. As a segment of the traditional embedded hard disk recorders, the car-mounted hard disk recorders (definition of car-mounted hard disk recordings) have ushered in a lot of security. The company's pro-gaze.
Car DVRs are said to be new products of the times in the security industry. However, the technical content, I am afraid that only people who have actually done car DVRs can understand.
The fault-tolerance and error-correcting capability of hard drives is a difficult problem that has been sought after in the IT hardware industry or the software industry since hard drives were available. For an embedded system, it is difficult to achieve a very perfect fault-tolerant and error-correcting design! However, the intention of the embedded system design is that the embedded system is originally designed for the pursuit of better stability and execution speed, but there is a problem that cannot be ignored that is poor portability, resulting in a design that cannot be too Big change. So its first design idea is very important. Embedded systems for hard disk fault tolerance error correction, the current effective way is to read and write control capabilities.
