Abstract:
In one embodiment, a programmable logic device such as an FPGA includes a programmable fabric adapted to operate normally and in a sleep mode, and a general purpose input/output port (I/O). The I/O port is adapted to function in conventional fashion during normal operation of the programmable fabric and as a wakeup control port during the sleep mode.
