Basic Architecture: Bus

Note that Pentium system bus architecture is more complex that this.

Basic Architecture: Bus (cont.)

• Address:– If I/O, a value between 0000H and FFFFH is issued.

– If memory, it depends on the architecture:• 20-bits (8086/8088)• 24-bits (80286/80386SX)• 25-bits (80386SL/SLC/EX)• 32-bits (80386DX/80486/Pentium)• 36-bits (Pentium Pro/II/III)

• Data:• 8-bits (8088)• 16-bits (8086/80286/80386SX/SL/SLC/EX)• 32-bits (80386DX/80486/Pentium)• 64-bits (Pentium/Pro/II/III)

• Control:• Most systems have at least 4 control bus connections (active low).• MRDC (Memory Read Control), MWRC, IORC (I/O Read Control), IOWC

Basic Architecture: Bus Standards

• ISA (Industry Standard Architecture): 8 MHz• 8-bit (8086/8088)• 16-bit (80286-Pentium)

• EISA: 8 MHz• 32-bit (older 386 and 486 machines).

• PCI (Peripheral Component Interconnect): 33 MHz• 32-bit or 64-bit (Pentiums)• New: PCI Express and PCI-X 533 MTS

• VESA (Video Electronic Standards Association): Runs at processor speed.

• 32-bit or 64-bit (Pentiums) • Only disk and video. Competes with the PCI but is not popular

Basic Architecture: Bus Standard (cont.)

• USB (Universal Serial Bus): 1.5 Mbps,12 Mbps, 480 Mbps and now 5Gbps.

• Newest systems.• Serial connection to microprocessor.• For keyboards, the mouse, modems and sound cards.• To reduce system cost through fewer wires.

• AGP (Advanced Graphics Port): 66MHz• Newest systems.• Fast parallel connection: Across 64-bits for 533MB/sec.• For video cards.• To accommodate the new DVD (Digital Versatile Disk) players.• Latest AGP 3.0 with peak bandwidth of 2.1GB/s.
