ABSTRACT:
A system for configuring a plurality of programmable devices may include an external memory, a master programmable device, and at least one slave programmable device. The programmable devices may have a parallel data bus connected in a daisy chain fashion. The programmable devices may further include a chip select signal that is also connected in a daisy chain. Special instructions embedded in the configuration bitstream, which may be stored in the external memory, are used by the programmable devices to control the configuration process.
