A data processor corecomprising a memory access interface portionoperable to perform data transfer operations between an external data source and at least one memory associated with said data processor core and a data processing portionoperable to perform further data processing operations in response to receipt of said processor clock signal CLK. The two portions of the core being operable to be independently enabled such that one portion may be active while the other is inactive.

Data transfer between an external data source and a memory associated with a data processor

A data processor corecomprising: a memory access interface portionoperable to perform data transfer operations between an external data source and at least one memoryassociated with said data processor core; a data processing portionoperable to perform data processing operations; a read/write portoperable to transfer data from said processor core to at least two busesA,B said at least two buses being operable to provide data communication between said processor coreand said at least one memory, said at least one memorycomprising at least two portionsA,B, each of said at least two busesA,B being operable to provide data access to respective ones of said at least two portionsA,B; arbitration logicassociated with said read/write port; wherein said arbitration logic is operable to route a data access request requesting access of data in one portion of said at least one memory received from said memory access interface to one of said at least two buses providing access to said one portion of said at least one memory and to route a further data access request requesting access of data in a further portion of said at least one memory received from said data processing portion to a further one of said at least two buses providing access to said further portion of said at least one memory, said routing of said data access requests being performed during the same clock cycle.
