摘要

The circuit has a RAM management interface connected to a bus system which exchanges data between RAMs and to an input-output interface and a computing unit. A bus image exchanges data between the RAM and a specific module for processing pre-programmed images. Distribution of access flow to the RAM between the two buses is according to use, and minimum access flow is guaranteed to each of the two buses.
