The functional safety features enabled by MIPI CSE help automotive system designers build systems that meet the requirements laid out in the ISO 26262 standard from ASIL B to ASIL D. They include the following:
- Cyclic redundancy check (CRC) to detect data transmission errors
- Frame counter to detect frame loss or duplication
- Timeout monitoring to detect any loss of data between image sensors and processors
CSE also provides an Enhanced Safety and Security Camera Control Interface (ESS CCI) that extends the Camera Control Interface (CCI) defined in CSI-2 by adding functional safety features, including CRC and a message counter, for control of CSI-2 camera interfaces.
Security features will be added through future CSE updates and the upcoming MIPI Security Specification.
