摘要： Methods and apparatus provide PCI Express support on a programmable device. A device includes a hard-coded transceiver that supports functionality associated with the PCI Express physical layer and link layer. The hard-coded transceiver can also support part of the PCI Express transaction layer. Soft-coded logic is used to support higher layer functionality including a portion of the transaction layer to allow custom configuration of PCI Express features such as virtual channels, buffers, prioritization, and quality of service characteristics. The hybrid solution reduces logic resource cost and provides an effective custom configurable solution.

摘要： Integrated circuits are provided that use on-chip data compression and decompression to minimize consumption of interconnect resources. Parallel-to-serial converter circuitry can use time-division multiplexing techniques to compress data. The compressed data may be conveyed between circuit blocks on the integrated circuit using a reduced number of parallel interconnect conductors. After the compressed data has been conveyed to its destination, a serial-to-parallel converter may use time-division demultiplexing techniques to decompress the data. Interconnect resources may be shared by dedicated circuits. With this arrangement, signals can be selectively steered through the appropriate dedicated circuitry to either maximize performance or to use compression and decompression to minimize interconnect resource consumption.

摘要： Multiplier circuitry that efficiently utilizes the hard and soft logic regions of a programmable logic device (PLD) is provided. The multiplier circuitry includes a partial product generation block, a compression block (e.g., a carry-save adder), and an carry-propagate adder stage. The partial product generation and compression block are implemented in hard logic while the carry-propagate adder is implemented in soft logic. Local or global routing may be used to connect the hard and soft multiplier components. The multiplier may further include a selectable input register in hard logic and/or a selectable output register in soft logic. This mixed-mode design allows for a substantial savings in the amount of hard logic required to implement the multiplier without a significant decrease in multiplier performance.

摘要： A method and system using a delay-locked loop (DLL) to provide multiple phase locked outputs in discrete phase intervals is disclosed. In one embodiment, a reference clock signal is transmitted through a delay chain having a plurality of delay elements. The delay chain is capable of generating a plurality of output clock signals from the reference clock signal. Each of the output clock signals are delayed in discrete phase shift intervals with respect the delay elements. A first of the output clock signals and the reference clock signal are coupled to a first phase comparator capable of forming a first DLL with the delay chain. A second of the output clock signals and the reference clock signal are coupled to a second phase comparator capable of forming a second DLL with the delay chain. The output clock signal from the first DLL or the second DLL may be programmatically selected.
