In VLSI design, a bus represents a group of parallel wires used to transmit knowledge, addresses, or management indicators between totally different elements of a system. It serves as a shared communication channel, permitting a number of modules to change data. As an illustration, an handle bus carries reminiscence addresses from the CPU to the reminiscence controller, enabling the CPU to entry particular reminiscence places.
A vector, within the context of VLSI, usually refers to a one-dimensional array of indicators or knowledge values. It is usually used to signify a multi-bit worth or a bunch of associated indicators handled as a single entity. For instance, a register storing a 32-bit worth will be considered as a vector of 32 particular person bits. Equally, a simulation testbench would possibly make the most of vectors to use a sequence of enter stimuli to a circuit beneath take a look at.
