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.
