Bus width may refer to: Bus § Dimensions, the width of the road vehicle; Bus width, in computer architecture, the amount of data that can be accessed or transmitted ...
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.
These modules usually combine multiple chips on one circuit board. SIMM modules connect to the computer via an 8-bit- or 32-bit-wide interface. RIMM modules used by RDRAM are 16-bit- or 32-bit-wide. [49] DIMM modules connect to the computer via a 64-bit-wide interface. Some other computer architectures use different modules with a different bus ...
Memory bus (interface) width: Each DDR, DDR2, or DDR3 memory interface is 64 bits wide. Those 64 bits are sometimes referred to as a "line." Those 64 bits are sometimes referred to as a "line." Number of interfaces : Modern personal computers typically use two memory interfaces ( dual-channel mode) for an effective 128-bit bus width.
Like the 68000, VME uses separate 32-bit data and address buses. The 68000 address bus is actually 24-bit and the data bus 16-bit (although it is 32/32 internally) but the designers were already looking towards a full 32-bit implementation. In order to allow both bus widths, VME uses two different Eurocard connectors, P1 and P2.
The corridor capacity in the passenger transport field refers to the maximum number of people which can be safely and comfortably transported per unit of time over a certain way with a defined width. The corridor capacity does not measure the number of vehicles which can be transported over such way, since the nuclear objective of passenger ...
Slots and connectors are only defined for a subset of these widths, with link widths in between using the next larger physical slot size. As a point of reference, a PCI-X (133 MHz 64-bit) device and a PCI Express 1.0 device using four lanes (x4) have roughly the same peak single-direction transfer rate of 1064 MB/s.
DDR SDRAM popularized the technique of referring to the bus bandwidth in megabytes per second, the product of the transfer rate and the bus width in bytes. DDR SDRAM operating with a 100 MHz clock is called DDR-200 (after its 200 MT/s data transfer rate), and a 64-bit (8-byte) wide DIMM operated at that data rate is called PC-1600, after its ...
