Advanced Technology Bus,
invented by IBM, named after the computer it was first used in. it was an extension to the PC BUS.
industry standard architecture Bus
A pool of PC-bus clone makers pooled there knowledge of the IBM buses and invented the ISA BUS
The 3 False starts at replacing the ISA BUS
IBM Micro Channel Architecture (MCA)
Extended ISA (EISA)
Vesa Local Bus (VL-BUS)
PCI (4 items)
1. Stands for Peripheral Component Interconnect
2. Developed by Intel
3. 32 bits wide / 33 Mhz / Auto config(PnP)
4. Allows for multiple types of buses.
1. Accelerated Graphics Port
2. A Special PCI slot that connects directly to the northbridge
2. Seen mostly only in very high end systems like servers.
3. 64bit wide bus.
What are Lanes?
Lanes are the two wires used by PCIe to communicate with the northbridge one lane receives while the other sends.
How many point-to-point connections can a PCIe card use? What is its bandwidth? What is most common?
Theoretically 320 Gbs Bandwidth
x1 or x4 is common for general use.
video cards usually use x16
1. Programable Interrupt Controller
2. A now obsolete: a traffic controller for IRG's
3. Only supports 15 IRQ's
1. I/O Advanced Programable Interrupt Controller
2. Usually built into the southbridge
3. This recieves the IRQ's from devices the charges the INT wire to the Processor.
DIRECT MEMORY ACCESS
THIS IS USED WHEN A DEVICE ACCESSES MEMORY DIRECTLY. MOST COMMON IN LAPTOPS
MEMORY ADDRESSES FOR CARDS
SOMETIMES A CARD WILL NEED MEMORY ADDRESSES SO THAT THE CPU CAN ACCESS ITS ONBOARD MEMORY. THIS IS AUTOMATIC.
THIS USED TO BE THE WINDOWS
HARDWARE COMPATIBILITY LIST. NOW IT IS THE WINDOWS LOGO'D HARDWARE LIST.
