Data processing method and apparatus

摘要

A method of data processing in which a composite data processing operation, for execution by a data processing device having a memory, is assembled by a user as a linked list of sub-operations selected from a set of possible data processing sub-operations, comprises the steps of: as a sub-operation is selected by the user for inclusion in the composite operation, loading into the memory sub-operation data defining parameters of that sub-operation including input and output interfaces of that sub-operation; and in response to an initiation of execution of a sub-operation, loading sub-operation program code into the memory for execution by the data processing device; in which the sub-operation data requires less memory space than the sub-operation program code. <IMAGE>
