Abstract: A logic device comprising reconfigurable core logic for use in conjunction with microprocessor-based computer systems which may be implemented as fully reconfigurable circuitry or a combination of reconfigurable logic and fixed logic sections. The core logic may contain parameterized functions that are selectable dynamically or during a manufacturing process and can allow for the dynamic, or predetermined, reallocation of external bandwidth between two or more ports. The fully reconfigurable circuitry, or a combination of reconfigurable and fixed logic, may be co-fabricated on a single die or formed by integrated circuit die stacking techniques. At least portions of the reconfigurable logic circuitry may be configured to function as one or more direct execution logic (DEL) reconfigurable processing elements that may function as effective peers with the associated microprocessor(s) in terms of accessing computing system resources.
