US Patent 8415974 Methods and circuits enabling dynamic reconfiguration

A method of enabling partial reconfiguration in a device having configurable resources is disclosed. The method comprises receiving a configuration bitstream comprising configuration bits; configuring the configurable resources of the device using the configuration bits of the configuration bitstream; receiving a request for a partial reconfiguration of the device; loading updated configuration bits into memory elements associated with a portion of the configurable resources in response to the request for a partial reconfiguration; and providing a status of the partial reconfiguration while loading the updated configuration bits. A circuit for enabling partial reconfiguration in a device having configurable resources is also disclosed.
