S5935

The S5935 was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabili capabili-ties. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the sys sys-tem's processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry's need for a bus stan stan-dard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering perfor perfor-mance more than adequate for the most demanding applications such as full-motion video.

Applied Micro Circuits Corporation (AMCC), the pre pre-mier supplier of single chip solutions, has developed the S5935 to solve the problem of interfacing applica applica-tions to the PCI Local bus while offering support for newer PCI chipsets and operating systems. The S5935 is a powerful and flexible PCI controller sup sup-porting several levels of interface sophistication. At the lowest level, it can serve simply as a PCI bus Target with modest transfer requirements. For high-perfor perfor-mance applications, the S5935 can become a Bus Master to attain the PCI Local bus peak transfer capa capa-bility of 132 MBytes/sec. The S5935 PCI controller also maintains dropin compatibility for upgrading many existent S5933 designs requiring migration into new motherboard architectures, PCI BIOSs and software operating systems.
