Northbridge
the Northbridge is the chip, or collection of chips, that connect a Central Processing Unit (CPU) to memory, (PCI) bus, Level 2 (L2) cache and (AGP) activities.
-
The Northbridge chip communicates with the CPU through the x
Frontside Bus (FSB)
-
Connects CPU -> RAM/PCI/L2 Cache/AGP
Northbridge
-
The Northbridge can consist of x unlike the Southbridge which is typically only y
- Northbridge: multiple chips (possibly)
- Southbridge: 1 chip
-
- PATA/IDE:
- 40 pins
- 1st pin marked by red wire
- Originally supported 16MB/s
-
Later standard of PATA allowed for x connections
80 (2 per pin), allows for faster transfer rate
-
Mainboards normally have x PATA connections available, and support y devices on each connection.
2, 2
-
Later versions of PATA increased the speed to x
33, 66, 100, 133 MB/s
-
SATA: Unlike Parallel ATA, only one hard drive per port is allowed.
True
-
SATA throughput range
1.5 GBps (192 MBps) - 6GBps
-
SCSI
SCSI, or Small Computer System Interface, is a standard for attaching multiple devices onto a single connection chain. It normally allows 7 or 15 devices depending on the standard (not counting the SCSI controller itself.) It is mostly used in servers.
-
SCSI connection chains must be terminated - otherwise you will have undesirable interference preventing the devices from working.
True
-
Standard for floppy discs
-
Southbridge
Southbridge is a chipset that manages the basic forms of input/output ( I/O ) such as ( USB ), serial, audio, Integrated Drive Electronics ( IDE ), and Industry Standard Architecture ( ISA ) I/O in a computer.
-
Industry Standard Architecture (ISA)
- This architecture was originally used in the IBM PC/XT and PC/AT used for connecting peripheral devices. It has been made obsolete by PCI.
- -62 pins
-
-
ISA supports up to
16 devices
-
Accelerated Graphics Port (AGP)
- A standard for 3-D graphic interfaces. Its first incarnation had a bandwidth of 266MBps with 2x, 4x, and 8x versions later following.
- Being made obsolete by PCIe
-
Control Bus:
The physical connections that carry control information between the CPU and other devices within the compute
-
Is SRAM faster than DRAM?
Yes
-
Interrupt Requests (IRQ)
Interrupt Requests (IRQ) are hardware lines which devices can send interrupt signals to the CPU.
-
IRQ0
The reserved interrupt for the internal system timer. Used exclusively for internal operations and is not available to peripherals or other devices. A conflict on this interrupt would indicate a hardware problem on the system board.
-
IRQ1
This interrupt is used only for the keyboard/keyboard controller. A conflict on this interrupt would indicate a hardware problem on the system board.
-
IRQ2
- This interrupt is a cascade for IRQs 8 to 15, allowing the use of extra IRQs 8 to 15.
- Conflicts on this line come from trying to use a device on IRQ2 and another on IRQ9 at the same time
-
IRQ3
This interrupt is used for COM2 and COM4 (second serial port and fourth serial port). It is a popular option for modems and sound cards.
-
