Abstract
An architecture is disclosed to provide high-speed input/output interface capabilities for programmable devices. One or more configurable input/output circuits are situated between the input/output drivers and the programmable core circuitry of the programmable device. The input/output circuits are optimized for the high-speed requirements of the input/output interface standards, with each input/output circuit configurable to support numerous, different input/output interface standards. The programmable core circuitry may be utilized to support the lower-speed requirements of the input/output interface standards.
