Abstract
An interfacing circuitry for a semiconductor circuit of a computer system selects the semiconductor circuit for a device operation in accordance with data, addresses, and control information received from a multiline bus of the computer system in a form of packets. The computer system has a plurality of semiconductor circuits. The interfacing circuitry is coupled to the multiline bus. The multiline bus has a total number of lines less than a total number of bits in any single address. The interfacing circuitry resides inside the semiconductor circuit and includes a decoder for decoding the packets received to identify the data, addresses, and control information. A control logic circuitry is coupled to the decoder circuitry for controlling device operation of the first semiconductor circuit in accordance with the data, addresses, and control information received. A register circuitry is coupled to the decoder and the control logic circuitry for storing a first value corresponding to a first predetermined time period during which the interfacing circuitry must wait before transmitting reply information through the multiline bus in response to the data, addresses, and control informa…
