SIS5503 PCI System I/O

The SiS5501(PCMC) bridges between the host bus and the PCI local bus. The SiS5501 (PCMC) monitors each cycle initiated by the CPU, and forwards it to the PCI bus if the CPU cycle does not target the local memory. For the CPU or the PCI bus to the local memory cycles, the built-in Cache and DRAM Cont.

The chipset is developed by using a very high level of function integration and system partitioning. With the SiS5501, SiS5502, and SiS5503 chipset, only 12 TTLs (include 3 DRAM address buffer) a.
