A flash reconfigurable programmable logic device is applied as a dynamic execution unit for a sequence of instructions. The sequence of instructions includes control portion, and a portion which indicates which configuration of the flash configurable programmable logic device is to be used with that instruction. In each execution cycle, a configuration is selected in accordance with the instruction being executed, switching from one configuration of the programmable logic device to any other configuration stored on the device in a single cycle. The configuration store stores a set of configuration words defining respective logic functions of the configurable logic elements in the programmable logic device. The configuration select circuits operate to apply a selected configuration word from the set of configuration words to configure the configurable logic elements. An instruction store stores a sequence of instructions for execution by the programmable logic device. Sequencing logic is coupled to the instruction store and configuration select circuits on the programmable logic device. The sequencing logic controls the configuration select circuits to apply configuration words from the set of configuration words during respective execution cycles, in response to the sequence of instructions.
