ABSTRACT:
To speed up data transfer, one embodiment of the invention features a transmission gate arrangement which pre-charges and transfers data in internal and external buses with the same timing and which further initializes the internal bus and a device such as an ALU, every bus cycle. A second embodiment speeds the data transfer in the buses by providing two data transfer paths through the interconnected buses and reducing the combined resistances of the internal and external buses.
