摘要： An integrated circuit device (105) comprising at least one memory interface module (130) arranged to be operably coupled between at least one data storage device (150) and a plurality of master devices (1 10) within a data processing system (100). The at least one memory interface module (130) comprises a plurality of buffers (138, 442, 444, 445, 446, 448) and at least one data access control module (132, 430, 435). The at least one data access control module (132, 430, 435) being arranged to fetch data from the at least one data storage device (150) in response to a received memory access request comprising a master device identifier (141 ), select at least one buffer (138, 442, 444, 445, 446, 448) based at least partly on the master device identifier (141 ) of the received access request, and load the fetched data into the selected at least one buffer (138, 442, 444, 445, 446, 448).

摘要： A method (1) of establishing pre-fetch control information from an executable code is described. The method comprises inspecting (10) the executable code to find one or more instructions corresponding to an unconditional change in program flow during an execution of the executable code when the executable code is retrieved from a non-volatile memory [NVM memory] (320) comprising a plurality of NVM lines (321A, 321C, 321Z). For each unconditional change of flow instruction in the executable code, the method comprises establishing (11) a NVM line address of the NVM line containing said unconditional change of flow instruction; establishing (12)] a destination address associated with the unconditional change of flow instruction; determining (13) whether the destination address is in an address range corresponding to a NVM-pre-fetch starting from said NVM line address; establishing (14) a pre-fetch flag (341A) indicating whether the destination address is in the address range corresponding to a NVM-pre-fetch starting from said NVM line address; and recording (15) the pre-fetch flag in a pre-fetch control information record (340). Also, a NVM controller, a device, a processor system and computer program products are described.
