Bus Architectures Flashcards
A breakdown of Bus Architectures
What does PCI stand for?
Personal Component Interconnect
What is the PCI bus width (in bits) and what is its speed?
The width of a PCI bus is 32/64 bits and its speed is 33 MHz.
What does AGP stand for?
Accelerated Graphics Port
What is the AGP bus width (in bits) and its speed?
The AGP bus width is 32 bits. It’s speeds vary. 66 MHz (1x), 133 MHz (2x), 266 MHz (4x), and 533 MHz (8x).
What does PCMCIA stand for?
Peripheral Component Microchannel Interconnect Architecture.
What is the bus width (in bits) and speed of the PCMCIA architecture?
A PCMCIA bus’ width is 16 bits and the speed is 33 MHz
What does PCI-X stand for?
Peripheral Component Interconnect eXtended
What is the PCI-X Architecture bus width (in bits) and speed?
The PCI-X architecture bus width is 32/64 bits and its speeds vary between 66/133/266/533 MHz.
What does PCIe stand for?
Peripheral Componnent Interconnect Express
What is a PCIe bus’ width (in bits) and speed?
PCIe architecture uses multiple lanes with each carrying 250mbps each. A PCIe x1 slot carries 250mbps. PCIe x4 can carry 1 GBps. These speeds are doubled with PCIe 2.0.
