Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus [1] (historically also called data highway [2] or databus) is a communication system that transfers data between components inside a computer, or between computers.
Practically all parallel communications protocols use synchronous transmission. For example, in a computer, address information is transmitted synchronously—the address bits over the address bus, and the read or write strobes of the control bus. Single-wire synchronous signalling
This bus: provides fully synchronous movement of GPR data between CPU and slave logic; functions as a synchronous, nonmultiplexed bus; has separate buses to read and to write data; consists of a single-master, multiple-slave bus; includes a 10-bit address bus; features 32-bit data buses; uses two-cycle minimum Read/Write cycles
A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and ...
The Wishbone Bus is an open source hardware computer bus intended to let the parts of an integrated circuit communicate with each other. The aim is to allow the connection of differing cores to each other inside of a chip. The Wishbone Bus is used by many designs in the OpenCores project. Wishbone is intended as a "logic bus".
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger telecommunications networks.
The Synchronous Backplane Interconnect (SBI) was the internal processor-memory bus used by early VAX computers manufactured by the Digital Equipment Corporation of Maynard, Massachusetts. The bus was implemented using Schottky TTL logic levels and allowed multiprocessor operation.
In event driven architectures, synchronous transactions can be achieved through using request-response paradigm and it can be implemented in two ways: [16] Creating two separate queues: one for requests and the other for replies. The event producer must wait until it receives the response. Creating one dedicated ephemeral queue for each request.
