The invention discloses a system on chip and a timestamp marking method thereof, a storage medium and electronic equipment. The timestamp marking method of the system on chip comprises the following steps: receiving to-be-marked data transmitted by at least one off-chip device; determining a target hardware clock from a plurality of hardware clocks included in the system on chip according to the to-be-marked data; according to the target hardware clock, determining the time when the to-be-marked data is transmitted to the system on chip; and marking a hardware timestamp on the to-be-marked data based on the time when the to-be-marked data is transmitted to the system-on-chip, so as to obtain marked data. According to the method, the data is stamped according to the time read by the hardware clock when the data enters the system-on-chip, the accuracy of the timestamp marked on the data can be improved, reliable data support is provided for guaranteeing safe driving of the vehicle, and safe driving of the vehicle is guaranteed.
公开了一种片上系统及其时间戳标记方法、存储介质及电子设备。其中片上系统的时间戳标记方法包括:接收至少一个片外设备传输的待标记数据;根据待标记数据,从片上系统包括的多个硬件时钟中确定目标硬件时钟;根据目标硬件时钟,确定待标记数据传输至片上系统的时间;基于待标记数据传输至片上系统的时间,对待标记数据进行硬件时间戳的标记,得到已标记数据。该方法在数据进入片上系统时根据硬件时钟读取的时间对数据打时间戳,能够提高对数据标记的时间戳的准确度,为保障车辆安全行驶提供可靠的数据支撑,保障车辆安全行驶。
