    摘要： A programmable logic array integrated circuit has a number of programmable logic modules which are grouped together in a plurality of logic array blocks ("LABs"). The LABs are arranged on the circuit in a two dimensional array. A conductor network is provided for interconnecting any logic module with any other logic module. In addition, adjacent or nearby logic modules are connectable to one another for such special purposes as providing a carry chain between logic modules and/or for connecting two or more modules together to provide more complex logic functions without having to make use of the general interconnection network. Another network of so-called fast or universal conductors is provided for distributing widely used logic signals such as clock and clear signals throughout the circuit.

    摘要： A programmable logic integrated circuit device has several features which help it perform according to the PCI Special Interest Group's Peripheral Component Interface (“PCI”) signaling protocol. Regions of programmable logic within the device are closely coupled to the data signal output pins and clock signal input pins such that delay between application of a clock signal to the device and output of a data signal from the device is within PCI signal standards for delay. The device also includes output circuitry that can be configured to selectively invert signals to output enable and data input enable terminals of the output circuitry.

    摘要： A programmable logic array integrated circuit device includes a plurality of regions of programmable logic disposed on the device in a two-dimensional array of intersecting rows and columns of such regions. Each row has a plurality of adjacent horizontal conductors, and each column has a plurality of adjacent vertical conductors. The regions in a row are interspersed with groups of local conductors which interconnect the adjacent regions and the associated horizontal and vertical conductors. The local conductors can also be used for intra-region communication, as well as communication between adjacent regions. Secondary signals such as clocks and clears for the regions can be drawn either from dedicated secondary signal conductors or normal region inputs. Memory cell requirements for region input signal selection are reduced by various techniques for sharing these memory cells.
