Chip-Set

Chip-Set

The chip-set comprises three chips. These interface between the three main buses (the Processor-Local bus, the PCI bus and the ISA bus).

• The TXC chip (82439HX) is a combined PL/PCI bridge and cache

controller and main memory controller and PCI-to-PL bus data path.

• The PIIX3 chip (82371SB) is a combined PCI/ISA bridge and IDE

controller and USB controller.

• The Super I/O chip (37C932) is a combined serial interface and parallel

interface and keyboard controller and mouse controller and flexible disk drive controller.

 

The TXC and PIIX3 chips are PCI 2.1 compliant, and provide for PCI

 

Concurrency. Concurrent data transfers that do not contest for the same

 

resources (such as processor to memory concurrent with PCI peer to peer,

 

or processor to ISA device concurrent with PCI device to memory) are

 

allowed to interleave their transfers more finely than with previous chip

 

sets. This has little effect on the throughput of the system, but results in a

 

greatly reduced worst-case latency. This leads to a much smoother

 

operation of video capture, MPEG clips and audio clips.

 

To find out more about how this is achieved, the reader is referred to the

 

Intel documentation on the 82430HX chip set. Relevant key words include:

 

the multi-transaction timer (MTT), the passive release mechanism, and

 

the PCI delayed transaction mechanism.

 

PL/PCI Bridge Chip (82439HX)

 

The bridge between the Processor Local Bus (PL Bus) and the PCI Bus is

 

encapsulated in a 324 pin ball grid array (BGA) package.

PL Bus Interface

The TXC chip monitors each cycle that is initiated by the processor, and

 

forwards those to the PCI bus that are not targeted at the local memory. It

 

translates PL bus cycles into PCI bus cycles.

 

The chip supports the SMM mode of the Pentium processor, the CPU stop

 

clock hardware function, and the keyboard lock function. These are used by

 

the LittleBen chip, as described on page 73.
