  1. Review Week1 UPM ECC3105 S1-12/13

  2. Week2 Outline • Basic Architecture – BUS UPM ECC3105 S1-12/13

  3. Basic Architecture: Personal Computer Memory bus VESA PCI EISA ISA Bus USB UPM ECC3105 S1-12/13

  4. Microprocessor Memory Graphic Card Northbridge Memory USB PCI/PCIe IDE/Parallel ATA Southbridge Ethernet Serial ATA Figure 2 Basic Architecture: Personal Computer (cont.) UPM ECC3105 S1-12/13

  5. Basic Architecture: Bus Note that Pentium system bus architecture is more complex that this. UPM ECC3105 S1-12/13

  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 UPM 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 UPM 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.

  10. ECC3105 Assignment 1 (Deadline: 26/09/2012, 0900hr) • Task: • Based on the given picture, please label the components appropriately. • Give the definition of Moore’s Law and its relation to our course. • Some says Moore’s Law will get to an end. Name the reasons why Moore’s Law will end? • Please give at least 3 answers for each question: • Why do we need to learn about microprocessors. • What do you aspect to learn from microprocessor course.
