摘要：
A method of controlling direct memory access of a peripheral memory of a peripheral by a master is described. The method includes checking whether there is a pending request from the peripheral for a direct memory access service, establishing whether an access condition is satisfied in dependence on at least whether there is a pending request, and, if the access condition is satisfied, granting access to the master. Also, an associated device and an associated computer program product are described.
