Abstract
Various techniques are disclosed herein to provide an improved approach to the loading of configuration data into configuration memory of programmable logic devices. For example, in accordance with one embodiment of the present invention a method of configuring a programmable logic device includes reading a first bitstream from a first memory block of an external memory device. The first bitstream is checked for errors and a second bitstream is read from a second memory block of the external memory device if an error is detected. Configuration memory of the programmable logic device is programmed with configuration data provided in one of the first bitstream and the second bitstream.
