Abstract

An integrated circuit device comprising at least one memory interface module arranged to be operably coupled between at least one data storage device and a plurality of master devices within a data processing system. The at least one memory interface module comprises a plurality of buffers and at least one data access control module. The at least one data access control module being arranged to fetch data from the at least one data storage device in response to a received memory access request comprising a master device identifier, select at least one buffer based at least partly on the master device identifier of the received access request, and load the fetched data into the selected at least one buffer.
