System and method for accessing a shared resource

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, said exploitation comprising a plurality of data transfers between the master processing unit and the shared resource, each shared resource having an associated maximum bandwidth, comprising, for at least one said shared resource:

• for each master processing unit, a counter of a number of data transfers between said master processing unit and said shared resource, and a comparator configured for comparing the number of transfers to a bandwidth limit associated with said shared resource, said bandwidth limit being a fraction of said maximum bandwidth,
• a pacing unit configured for resetting each transfer number counter after a time period of predetermined length has elapsed,
• said access system being configured 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 of said shared resource by said master processing unit once each counter has been reset.
