CAM First Chapter

  1. 1. The form factor of a motherboard determines the specifications for its general shape and size. Form Factor It also specifies what type of case and power supply will be supported, the placement of mounting holes, and the physical layout and organization of the board. AT Prior to 1997, IBM computers used large motherboards. After that, however, the size of the motherboard was reduced and boards using the AT (Advanced Technology) form factor was released. The AT form factor is found in older computers (386 class or earlier). ATX With the need for a more integrated form factor which defined standard locations for the keyboard, mouse, I/O, and video connectors, in the mid 1990's the ATX form factor was introduced.
  2. 2. ATX defined to address four areas of improvement: enhanced ease of use, better support for current and future I/O, better support for current and future processor technology, and reduced total system cost
  3. 3. Micro-ATX This form factor was developed as a natural evolution of the ATX form factor to address new market trends and PC technologies. MicroATX supports: • Reduction in the physical size of the motherboard • Reducing the number of I/O slots supported on the board • Current processor technologies • The transition to newer processor technologies • AGP high performance graphics solutions • Smaller motherboard size • Smaller power supply form factor
  4. 4. LPX White ATX is the most well-known and used form factor, there is also a non-standard proprietary form factor which falls under the name of LPX, and Mini-LPX. The LPX form factor is found in low-profile cases NLX Boards based on the NLX form factor hit the market in the late 1990's. This "updated LPX" form factor offered support for larger memory modules, tower cases, AGP video support and reduced cable length. BTX The BTX, or Balanced Technology Extended form factor, was developed to take advantage of technologies such as Serial ATA, USB 2.0, and PCI Express. The BTX form factor provides the industry push to tower size systems with an increased number of system slots. Supports current and future processor technologies Supports new Accelerated Graphics Port (A.G.P.) high performance graphics solutions Supports tall memory technology Provides more system level design and integration flexibility
  5. 5. A System Configuration is defined as the computers, processes, and devices that compose the system and its boundary. The system configuration is the specific definition of the elements that define and/or prescribe what a system is composed of. System Configuration System configuration is the process of setting up your hardware devices and assigning resources to them so that they work together without problems.
  6. 6. Chipset : Combining a PC’s sophisticated logic circuitry onto a few chips shorten the signal path allows the circuits to operate at higher speed is known as chipset. FSB : The pathway between CPU & RAM is called Front Side Bus.
  7. 7. North Bridge IC South Bridge IC
  8. 8. Northbridge Chip : This is the chip responsible for interfacing the CPU, main memory, local bus and main system bus. • Connects CPU via FSB (400/266/200/133/100/66MHz) • Various types of processors are supported. • Connects the slower AGP (533/266/133/66MHz) • It supports the various memory types (PC133 SDRAM or PC800 RDRAM) • It supports the memory technologies (64 128 Mbit SDRAM) • Parity or ECC type of memory error correction supported. • Number of processors are supported (for multiprocessing)
  9. 9. Southbridge Chip : Since ports and buses generally operate at speeds that are far slower than the FSB, system support provided through a second chip called Southbridge chip. It handles the system’s peripheral and I/O bus operations. It supports ISA bus bridged with PCI bus. Supports one or more USB, serial and a parallel port(s) Supports an infrared (IrDA) port. Supports two channel hard drive controller. (Dual ATA) Handles power management features. Handles keyboard controller, including support for a PS/2 mouse.
  10. 10. • Hub Architecture: Intel introduced its hub architecture starting with the 820 chipset, which divides control between a memory controller chip (MCH) and an I/O controller chip (ICH).
  11. 11. Hub Architecture: North Bridge chip is called a Memory Controller Hub (MCH) and South Bridge is called an I/O Controller Hub (ICH). Now MCH is replaced with Graphics Memory Controller Hub (GMCH) & connects through dedicated hub interface that is twice as fast as PCI. Advantages over North/South Bridge Architecture •It’s faster – The Accelerated Hub Architecture (AHA) interface used by the 8xx series has twice the throughput of PCI. Also 9xx series use DMI (Direct Media Interface), which is 7.5x to 15x faster than PCI •Reduced PCI loading – The hub interface is independent of PCI. This improves performance of all PCI bus connected devices. •Reduced board wiring – The AHA interface is only 8 bits wide & requires only 15 signals to be routed on the motherboard, while MDI is only 4 bits wide requiring only 8 pairs of signals.

  29. 29. It contains several important core components, including the chipset, which controls many of the most essential functions of the PC. It directly interfaces with other key components of the PC, and is responsible in large part for the stability, feature support, expandability and upgradeability of any system. Form Factor - The initial decision is the form factor of the motherboard, which must be mated to that of the power supply and case. CPU Support - The chipset must support the particular CPU you want to use Chipset - The chipset is the core logic of the motherboard and is responsible for most of its characteristics Video Support - The video card either goes into a slot on the motherboard, or its functionality is integrated onto it. Memory Support - Motherboards vary in terms of the number of memory slots they provide, and also what sizes and types of modules are supported.
