Abstract
A method for transferring messages from a producer element to a consumer element uses a memory shared between the producer element and the consumer element, and a hardware queue including several registers designed to contain addresses of the shared memory. The method includes the steps of storing each message for the consumer element in the shared memory in the form of a node of a linked list, including a pointer to a next node in the list, the pointer being initially void, writing successively the address of each node in a free slot of the queue, whereby the node identified by each slot of the queue is the first node of a linked list assigned to the slot, and when the queue is full, writing the address of the current node in memory, in the pointer of the last node of the linked list assigned to the last slot of the queue, whereby the current node is placed at the end of the linked list assigned to the last slot of the queue.
