1. A method for automatic generation of a specification for a configurable processor, the method comprising: generating a specification of a first stream memory interface to be operable to access data in accordance with a first stream descriptor; generating a specification of a second stream memory interface to be operable to access data in accordance with a second stream descriptor; generating a specification of an interim data storage device to be accessed by the first stream memory interface and the second stream memory interface and to be operable to receive data from a first computational module via the first stream memory interface and to transfer data to a second computational module via the second stream memory interface; and outputting the specification of the configurable processor, the specification of the configurable processor comprising the specifications of the first stream memory interface, the second stream memory interface and the interim data storage device.
