Questions tagged [bus]

A Bus is a physical device used to connect different functional blocks of a computer or a different computers in order to communicate them together. Also Bus is a data type in MATLAB language used to bundle some data to virtual (just for useful rendering) or non-virtual (for contiguous memory allocation) structure.

The Bus advantages (as physical device) over wires are reducing the needed number of wires and catholicity. The main characteristics of Buses are width (amount of bits can be transmitted at once) and frequency (work speed).

The Bus as a structure of MATLAB language used to bundle different variables (or signals, for example in Simulink) in one structure. Can be used as virtual bus just for convenient accessing to variables and for reducing number of wires at Simulink diagram or as non-virtual - Nonvirtual buses use contiguous memory allocation for variables.
