  • Patent number: 4583193
    Abstract: An integrated circuit mechanism is provided for coupling the separate sets of output lines from a plurality of programmable logic arrays to the same set of bus lines of plural-line signal transfer bus. This coupling mechanism includes precharge circuitry for precharging each of the bus lines during a first time interval. This coupling mechanism also includes a separate strobe signal line for each programmable logic array and circuitry for activating one of the strobe signal lines during a second time interval for selecting a particular programmable logic array. This coupling mechanism further includes a separate output buffer for each programmable logic array. Each such output buffer includes a plurality of buffer stages for individually coupling the different ones of the programmable logic array output lines to their respective bus lines.

  • Patent number: 4567561
    Abstract: A digital data signal transfer mechanism is provided for use in large scale integration digital data processor circuitry formed on an integrated circuit chip. The signal transfer mechanism includes a plural-bit data bus formed on the integrated circuit chip for transferring plural-bit binary data signals between different locations on the chip. The signal transfer mechanism also includes plural-bit signal source circuitry and plural-bit signal destination circuitry formed on the integrated circuit chip and coupled to the plural-bit data bus for respectively supplying plural-bit data signals to and receiving plural-bit data signals from the bus.
