System Block Diagram
OVERVIEW
The BCM5714S device is a highly integrated communication and
storage bridge for entry-level servers and embedded applications. The
primary applications are UP and DP servers featuring PCI Express
connectivity for I/O expansion.
The primary features of the BCM5714S are:
•
Dual Gigabit NIC ports
•
One full 64-bit/133-MHz PCI-X 1.0 bus
•
Host interface of PCI Express
•
Integrated SerDes
The BCM5714S connects to server chip sets with an x4 PCI Express
interface and provides an independent PCI-X 1.0 bus for peripheral
connectivity. The x4 PCI Express interface is a flexible design and
supports x1 and x2 PCI Express connectivity as well. The PCI-X bus is
64 bits wide and runs at 133 MHz.
As an integrated I/O bridge that provides a high performance data flow
path between the PCI-E host interface and the integrated I/O sub system,
the PCI-X bus provides high-performance I/O expansion within the
system, and the Gigabit Ethernet interfaces provide high performance
network interfaces to the external world. The 64-bit PCI-X bus segment
operates at 33 MHz, 66 MHz, 100 MHz, and 133 MHz. The Gigabit
Ethernet Interface represents Broadcom's fourth generation of server
controllers with fully integrated SerDes transceivers.
The PCI-X Bridge also has the following features:
•
Allows concurrency between the PCI Express and the PCI-X buses
•
Eight deep PCI Express-to-PCI-X memory write posting (PCI
Express-to-PCI-X transactions)
•
Four deep PCI Express-to-PCI-X non-posted request queue (PCI
Express-to-PCI-X transactions)
•
Caching with a 16-deep, 32-byte I/O cache for PCI to main memory
transactions for each PCI bus
•
Support write-through caching protocol
•
Supports up to 14 outstanding split transactions (PCI-X-to-main
memory transactions)
•
Eight-deep PCI-X-to-PCI Express request queue (PCI-X-to-main
memory transactions)
•
Parity protection on the PCI-X bus in a conventional PCI and PCI-X
mode1
•
Optional ECC protection on the PCI-X bus in PCI-X mode1
•
Three programmable regions each for PCI-X memory, and one
region for I/O
•
VGA-compatible addressing support
•
Multiple I/O APIC support
•
Peer-to-peer transfer support
•
Integrated PCI-X bus arbitration that supports up to four PCI-X bus
masters
•
PCI-X bus error reporting
•
