An address bus is a bus that is used to specify a physical address. When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus (the value to be read or written is sent on the data bus). The width of the address bus determines the amount of memory a system can address.
The concepts of reservation stations, register renaming, and the common data bus in Tomasulo's algorithm presents significant advancements in the design of high-performance computers. Reservation stations take on the responsibility of waiting for operands in the presence of data dependencies and other inconsistencies such as varying storage ...
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 ...
Bus (computing), a communication system that transfers data between different components in a computer or between different computers Memory bus, a bus between the computer and the memory; PCI bus, a bus between motherboard and peripherals that uses the Peripheral Component Interconnect standard
This places an upper limit on the length of a parallel data connection that is usually shorter than a serial connection. Complexity: Parallel data links are easily implemented in hardware, making them a logical choice. Creating a parallel port in a computer system is relatively simple, requiring only a latch to copy data onto a data bus.
The ccTalk multidrop bus protocol uses an 8 bit TTL-level asynchronous serial protocol.It uses address randomization to allow multiple similar devices on the bus (after randomisation the devices can be distinguished by their serial number). ccTalk was developed by CoinControls, but is used by multiple vendors.
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".
D-Bus (short for "Desktop Bus" [4]) is a message-oriented middleware mechanism that allows communication between multiple processes running concurrently on the same machine. [5] [6] D-Bus was developed as part of the freedesktop.org project, initiated by GNOME developer Havoc Pennington to standardize services provided by Linux desktop environments such as GNOME and KDE.
