What (who) is local bus - definition

COMPUTER BUS THAT CONNECTS DIRECTLY, OR ALMOST DIRECTLY, FROM THE CPU TO ONE OR MORE SLOTS ON THE EXPANSION BUS

Processor local bus
<hardware> A bus connecting a processor to memory, usually on the same circuit board as opposed to a backplane and therefore faster. Various proprietary local busses for personal computers are still in use. The most common are Vesa local bus (VLB or VL), and Peripheral Component Interconnect (PCI). Some computers, e.g. notebook computers, use a local bus with no expansion slots. Previous non-local bus standards include ISA, EISA and MCA. (1997-08-25)

Processor local bus
In computer architecture, a local bus is a computer bus that connects directly, or almost directly, from the central processing unit (CPU) to one or more slots on the expansion bus. The significance of direct connection to the CPU is avoiding the bottleneck created by the expansion bus, thus providing fast throughput.

  • ISA]] slots of various feature levels. The top three are 16-bit ISA. The middle three are VLB; 16-bit ISA with the added slot (leftmost brown sections). The bottom (shorter) slot is 8-bit ISA. A card installed in this motherboard would have its mounting bracket on the right, which normally would be the "back" of the computer case.

Local bus

In computer architecture, a local bus is a computer bus that connects directly, or almost directly, from the central processing unit (CPU) to one or more slots on the expansion bus. The significance of direct connection to the CPU is avoiding the bottleneck created by the expansion bus, thus providing fast throughput. There are several local buses built into various types of computers to increase the speed of data transfer (i.e. bandwidth). Local buses for expanded memory and video boards are the most common. VESA Local Bus and Processor Direct Slot were examples of a local bus design.

Although VL-Bus was later succeeded by AGP, it is not correct to categorize AGP as a local bus. Whereas VL-Bus operated on the CPU's memory bus at the CPU's clock speed, an AGP peripheral runs at specified clock speeds that run independently of the CPU clock (usually using a divider of the CPU clock).

Examples of use of local bus
1. A local bus half–full with passengers lumbered through unchecked.
2. Even small minivan type of local bus has those devices.
3. Members of the local bus drivers’ union staged a work stoppage during the funeral.
4. The fare structure will be approximately 1.5 times that of the local bus fare.
5. Commuters will be able to continue their journey using local bus routes with the same ticket, ISAP said.
