Abstract:
A field programmable device, comprising:a plurality of processing devices;a connection matrix interconnecting the processing devices and including a plurality of switches;a plurality of memory cells for storing data for controlling the switches to define the configuration of the interconnections of the connection matrix; andan isolating element for isolating the effect of the data stored in at least one group of the memory cells on the configuration of the interconnections so that the memory cells in that group are available for storing other data, wherein the isolating element is adapted to isolate each of the memory cells in a group from switches which are controllable by those memory cells, and wherein the content of memory cells determines current configuration of the interconnections of the connection matrix except where isolated by the isolating element, in which case the current configuration of relevant parts of the connection matrix is determined by a predetermined default configuration.
