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. The signal transfer mechanism further includes processor control circuitry coupled to the signal source and signal destination circuitry for enabling the signal source circuitry to put a plural-bit data signal onto the data bus during a first processor control cycle and for enabling the signal destination circuitry to take in this plural-bit data signal from the bus during a second and different processor control cycle. The inherent capacitance of the plural-bit data bus serves to store the plural-bit data signal during the first and second and any intervening processor control cycles.
