Abstract
The invention relates to a system for accessing a shared resource belonging to a hardware platform comprising a plurality of master processing units, each master processing unit being able to exploit a shared resource during an execution of a process, each shared resource having an associated maximum bandwidth. For at least one shared resource, the system includes a counter of a number of data transfers between said master processing unit and said shared resource, and a comparator suitable for comparing the number of transfers to a bandwidth limit, which is a fraction of said maximum bandwidth, associated with said shared resource, and a pacing unit suitable for resetting each counter after a time period of predetermined duration has elapsed. The access system is suitable for commanding, once said number of transfers associated with a master processing unit has reached said bandwidth limit, a suspension of the exploitation of said shared resource by said master processing unit, and a resumption of the exploitation once each counter has been reset.
