IC-integrated circuit, refers to all the electronic components, is set on silicon circuit module of a variety of electronic components to achieve a specific function. IC (integrated circuit) is a kind of miniature electronic devices or components. The adoption of a certain process, the transistor, resistor in a circuit, capacitance and inductance and components and wiring interconnection together, make on a small piece or a few small piece of semiconductor wafer or medium substrate, and then encapsulated in a tube and shell inside, as has the required the micro structure of circuit function; All elements on the structure is composed of a whole, make the electronic components to micro miniaturization, low power consumption, high intelligence and reliability is a major step forward. It marked the letters “IC” in a circuit. Inventor of integrated circuits for jack gill ratio (integrated circuit) based on germanium (Ge) and Robert noyce (integrated circuit) based on silicon (Si). In most applications in the semiconductor industry today is based on the silicon integrated circuits.
It is the most important part of electronic equipment, bear the computing and storage function. Integrated circuit application range covers almost all of military and civil electronic equipment. If the central processor CPU compared to the whole computer system‘s heart, then the motherboard chipset is the trunk of the whole body. For motherboard chipset almost determines the function of the main board, which affect the entire computer system performance of the play, chipset is the soul of the motherboard.
Chipset (Chipset) are the core part of the main board, according to the arrangement of position on the mainboard, usually divided into the northbridge and occurrence of the chip. AGP provide the type and frequency of CPU, memory, the type and capacity, ISA/PCI or AGP slot, ECC error correction and other support. Occurrence of the single chip provided for KBC (keyboard controller), the RTC (real time clock controller), USB (universal serial bus), Ultra DMA / 33 (66) EIDE data transmission mode and ACPI (advanced energy management) support, etc. The northbridge plays a dominant role, also known as the Bridge (the Host Bridge).
