6. 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 FZR Rev1.06UPM ECC3105 S1-12/13

7. 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 FZR Rev1.07UPM ECC3105 S1-12/13

8. 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.
