In a re-configurable semi-conductor integrated circuit device which, as made, comprises a plurality of cells (2) which have two or more possible configurations, means (3) for storing configuration data for at least two cell configurations (per cell), data memory (5) for the array of cells, and input/output channels for the device, improvements in flexibility and efficiency are made possible by the provision of a programmable micro-controller (9) and a direct memory access engine (11) controlled by the programmable micro-controller to control the transfer of data to and/or from:- the array memory; the input/output channels and the means storing configuration data. Re-configuration may be initiated by interrupt signals generated by an off-chip signal, an on-chip signal or an on-chip event. A plurality of programmable sequencers are used to generate a sequence of configuration data storage addresses. |
