Abstract
A programmable logic device is reconfigurable between two functionalities, while it is in use. The programmable logic device has a first store, into which configuration data may be downloaded from an external memory device, and a second store, in which a copy of the configuration data is maintained, with the functionality of the programmable logic device being determined by the copy of the configuration data, thereby allowing additional configuration data to be downloaded from the external memory device into the first store, while maintaining the functionality of the device. This allows the device to be used to provide two different functionalities, and to be switched between these two functionalities with minimal delay for reconfiguration of the device.
