ABSTRACT:
Various embodiments of a programmable logic device (PLD) capable of being dynamically partially reconfigured are disclosed. The PLD provides circuitry for changing its configuration data in whole or in part without halting the operation nor losing any of the logic state of the PLD. In one embodiment, data injection circuitry are added to a FIFO architecture to allow the user to inject data at random locations without disturbing the functionality of the PLD. In another embodiment, the PLD architecture is designed to provide for address wide or frame wide accessing of configuration bits. This allows for address wide configuration and reconfiguration.
