DOUBLE BUS ARCHITECTURE

摘要

The invention relates to an electronic circuit for the processing of images, comprising calculation means, input/output and communication interfaces, and at least one pre-programmed module specifically for the processing of images as well as at least one RAM, characterized in comprising at least one RAM management interface connected to a first bus, called the system bus for the exchange of data between said RAM and the calculation means or input/output interfaces and to a second bus called the image bus, for the exchange of data between said RAM and the pre-programmed module specifically for image processing. The distribution of access rate to the RAM between the two buses being adaptable according to use, a minimum access rate to the RAM being guaranteed for each of the two buses.
