Abstract
Access to a memory shared between a first interface and a second interface is arbitrated. Following a request to access the memory emanating from the second interface, while current access to the memory is granted to the first interface, a count is triggered having a maximum count time. A access to the memory is authorized for the second interface at the end of occupation of the access granted to the first interface if the end of occupation finishes before the end of the maximum count time, or otherwise at the end of the maximum count time.
