Block Diagram Of The SiS 648
Below is a block diagram of the 648 chipset, which consists of a Northbridge (648) and and a Southbridge (963). Interestingly enough, SiS decided against single-chip technology, which it had implemented with its 735 chipset.
The block diagram shows the basic architecture of the SiS 648 chipset.
