ABSTRACT:
A synchronization system includes an image processor, a RAM, a CPU with an R/W interface, and a time controller. The time controller generates synchronization signals based on image control signals and ALE signals respectively generated by the image processor and the CPU. The image processor and the CPU can access the RAM synchronously according to the synchronization signals.
