Most popular bussystems• Internal
– ISA / EISA– VLB– PCI– AGP
• External– USB– Firewire
ISA (1980)(Industry Standard
Architecture )
• 8-bit bus
• 16-bit bus (compatible to 8-bit)
ISA (1980)(Industry Standard
Architecture )• Graphiccards• Controllercards (storage)• Networkcards (MoDem, LAN)• Soundcards• Serial & parallel ports (com, lpt)• Replaced in new systems (PCI-
bus)
EISA (1988)(Extended Industry Standard
Architecture )• Extension of ISA-Standart• Bus-Mastering (direct
communication between cards)• Mainly used in Servers or network-
hosts• Compatible to ISA-Standart
32-bit EISA slot
16-bit ISA slot
Vesa-Local-Bus (VLB) (1992)(Video Electronics Standard
Association)• Compatible to ISA-standart• 32-bit bus• Mainly used for graphic- and videocards• extension of the 486 processor/memory
bus (only used in 486er systems)• Not established due to PCI-system in
connection with the Pentium-CPUs.
PCI (1993) (Peripheral Component Interconnect)
• Actual system standart• 32 and 64 bit bus (with Bus-
Mastering)• First system controlled by the
mainboards chipset• Usable for nearly all device cards
AGP (1997)(Accelerated Graphics Port)
• 64 bit bus• Used only for graphiccards• different modes:
– 1x standart– 2x double data rate per clock– 4x quad data rate per clock
• ability to share the main system memory with the video chipset
External Bus Systems
• USB 1.1• USB 2.0• Firewire 1 (i-link, IEEE 1394)• Firewire 2
USB 1.1 / 2.0(Universal Serial Bus)
• Hot plug Capability • Hot swap (PNP)• Built-in in all newer PCs• Built-in Power supply• Bandwith (max.): USB 1.1: 12Mbit / sec USB 2.0: 480Mbit / sec
Firewire 1 & 2
• Hot plug capability• Hot swap (PNP)• Requires additional controller• Built-in Power supply• Bandwith (max.): Fw 1: 100 / 200 / 400 Mbit / sec Fw 2: up to 3,2 Gbit / sec
