324-Pin MBGA 430TX PCIset Xcelerated

Controller (MTXC) with integrated Data

Paths

The Intel 430TX PCIset (430TX) consists of the 82439TX System Controller (MTXC) and the 82371AB PCI

ISA IDE Xcelerator (PIIX4). The 430TX supports both mobile and desktop architectures. The 430TX forms a

Host-to-PCI bridge and provides the second level cache control and a full function 64-bit data path to main

memory. The MTXC integrates the cache and main memory DRAM control functions and provides bus

control to transfers between the CPU, cache, main memory, and the PCI Bus. The second level (L2) cache

controller supports a writeback cache policy for cache sizes of 256 Kbytes and 512 Kbytes. Cacheless

designs are also supported. The cache memory can be implemented with pipelined burst SRAMs or DRAM

cache SRAMs. An external Tag RAM is used for the address tag and an internal Tag RAM for the cache line

status bits. For the MTXC DRAM controller, six rows are supported for up to 256 Mbytes of main memory.

The MTXC is highly integrated by including the Data Path into the same BGA chip. Using the snoop ahead

feature, the MTXC allows PCI masters to achieve full PCI bandwidth. For increased system performance, the

MTXC integrates posted write and read prefetch buffers. The 430TX integrates many Power Management

features that enable the system to save power when the system resources become idle.
