S82433NX

LOCAL BUS ACCELERATOR (LBX)

Intel 

82433LX 82433NX

1 0 ARCHITECTURAL OVERVIEW

The 82430 PCIset consists of the 82434LX PCMC

and 82433LX LBX components plus either a PCI

ISA bridge or a PCI EISA bridge The 82430NX PCI-

set consists of the 82434NX PCMC and 82433NX

LBX components plus either a PCI ISA bridge or a

PCI EISA bridge The PCMC and LBX provide the

core cache and main memory architecture and

serves as the Host PCI bridge An overview of the

PCMC follows the system overview section

The Local Bus Accelerator (LBX) provides a high

performance data and address path for the

82430LX 82430NX PCIset The LBX incorporates

five integrated buffers to increase the performance

of the Pentium processor and PCI master devices

Two LBXs in the system support the following areas

1 64-bit data and 32-bit address bus of the Pentium

processor

2 32-bit multiplexed address data bus of PCI

3 64-bit data bus of the main memory

In addition the LBXs provide parity support for the

three areas noted above (discussed further in Sec-

tion 1 4)

1 1 Buffers in the LBX

The LBX components have five integrated buffers

designed to increase the performance of the Host

and PCI Interfaces of the 82430LX 82430NX

PCIset

With the exception of the PCI-to-Memory write buffer

and the CPU-to-PCI write buffer the buffers in the

LBX store data only addresses are stored in the

PCMC component
