[0004] Higher address counts increase the complexity of the addressing logic necessary to implement such a bus
Furthermore, for this bus, the added complexity increases the complexity of the single-wire and two-wire data bus, thus increasing the overhead associated with the single-wire and two-wire data bus, such as the silicon area occupied by the bus interface

Methods and configurations of apparatuses for sharing a common address on a bus are disclosed. Embodiments may include a host for media management and one or more client devices coupled to the communication media. The host and / or one or more of the client devices may comprise a device capable of initiating a communication over a communication medium, also referred to as an initiating device. Additionally, the host and / or one or more client devices may include a device capable of receiving communications over a communication medium, also referred to as a receiving device. An application can transmit a command to request a response from one of the two or more devices sharing a common address. In particular, the driver of the initiating device may receive instructions from the application to send a command to the device, and the device may recognize this command based on a value associated with the command.
Description
technical field [0001] The present invention is in the field of communication between devices. In particular, the present invention relates to methods and arrangements for devices sharing a common address on a bus. Background technique [0002] Data buses are built into nearly all computers and processor-based devices to facilitate communication between the various components. For example, a data bus may facilitate communication between a processor and random access memory, other application specific integrated circuits (ASICs), and peripheral devices. While some buses require complex logic for coordination, high speed, and multiple wires for massive data transfers, other data buses are single-wire, low-speed buses with relatively simple logic. Single- and two-wire data buses avoid many of the problems faced by more complex buses, such as multiple traces, multiple pins, and high gate counts, making such buses significantly less expensive in terms of hardware and space requ...
