Abstract

Efficient access to a shared resource such as buffer memory by a number of users is achieved by providing a single access control device which is supplied with parameters appropriate to the user having access to the resource at the relevant time. In particular, in a network communication device in which MAC devices have a common buffer memory, appropriate pointers related to the users are supplied to a calculation means during access to the buffer by the various users.
