    Abstract: An improved method and apparatus for reloading frames in which errors are detected during the Programmable Logic Device configuration. A configuration data frame for a FPGA is loaded to the Frame register of the FPGA and also to an error detection circuit which detects errors with the loaded frame. An error counter value is maintained by the apparatus and is incremented each time an error with a frame is detected. The incremented value is compared by a Comparator circuit with a pre-determined threshold value nullnnull. If a match is found then the configuration process is aborted, else the data frame is reloaded in the configuration memory, transferred again to the frame register and rechecked for errors. If no error is detected with the reloaded frame, the error counter value is reset and the next frame is loaded until the FPGA configuration process is over.

    Abstract: An electronic circuit containing one or more digital synchronous sequential logic blocks at least one of which is either selected or deselected during operation. The electronic circuit includes an improved clock distribution scheme that reduces power consumption, comprising identifying means for determining the select/deselect state of each said deselectable synchronous sequential logic block, coupled to disabling means for disabling the clock input to each deselected synchronous sequential logic block.

    Abstract: This invention relates to a high performance interconnect architecture providing reduced delay minimized electro-migration and reduced area in FPGAs comprising a plurality of tiles consisting of interconnected logic blocks, that are separated by intervening logic blocks. Each set of interconnected logic blocks is linked by an interconnect segment that is routed in a straight line through an interconnect layer over intervening logic blocks and is selectively connected to the logic block at each end through a connecting segment.
