DESCRIPTION
The PCI Local bus concept was developed to break
the PC data I/O bottleneck and clearly opens the door
to increasing system speed and expansion capabili-
ties. The PCI Local bus moves high speed peripherals
from the I/O bus and places them closer to the 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-
dard which is not directly dependent on the speed,
size and type of system processor. It represents the
first microprocessor independent bus offering perfor-
mance more than adequate for the most demanding
applications such as full-motion video.
Applied Micro Circuits Corporation (AMCC), the pre-
mier supplier of single chip solutions, has developed
the S5935 to solve the problem of interfacing 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-
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-
mance applications, the S5935 can become a Bus
Master to attain the PCI Local bus peak transfer 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.
