Unsa maning Northbridge? Southbridge?

[GREENHILLS]

---

any easiest way to make us understand them?

[StyM]

northbridge = cpu + memory
southbridge = usb + hdd + floppy

ayaw nalang na problemaha bro kong unsa ning southbridge ug northbridge. Anyway these are interface or controller in the motherboard.
Sort of buses connected to these, cpu will determine which controller will be responsible to do something. like accessing memory, most likely will pass northbridge before going to cpu.

Bitaw bai, Northbridge is the controller that interconnects the CPU to memory via the frontside bus (FSB). Then it also connects peripherals via high-speed channels such as AGP and PCI Express. The Northbridge may include a display controller, obviating the need for a separate display adapter.

The Southbridge controller handles the remaining I/O, including the PCI bus, parallel and serial ATA drives (IDE), USB, FireWire, serial and parallel ports and audio ports. Earlier chipsets supported the ISA bus in the Southbridge. Starting with Intel's 8xx chipsets, Northbridge and Southbridge were changed to Memory Controller and I/O Controller.

sakto na.

In case for Athlon 64 / Opteron,
Part of a Northbridge--the memory controller is integrated into the CPU for Athlon64/Opteron CPU
so memory access for these processors are very fast
Connection to the PCIe/AGP is through the HyperTransport bus
