***Notes:...
***Info:
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 oi 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.

1.0. ARCHITECTURE OVERVIEW
The MTXC host bridge provides a completely integrated solution for the
system  controller  and datapath  components  in  a Pentium  processor
system. The MTXC Supports all Pentium family processors since P54C, it
has  64-bit Host  and DRAM  Bus Interface,  32-bit PCI  Bus Interface,
Second level Cache Interface, and it integrates the PCI arbiter.

The MTXC interfaces  with the Pentium processor host  bus, a dedicated
memory data bus, and the PCI bus (see Figure 1) [see datasheet].

The MTXC bus interfaces are  designed to interface with 2.5V, 3.3V and
5V busses. The  MTXC implements 2.5V and 3.3V  drivers and 5V tolerant
receivers. The MTXC connects directly to the Pentium processor 3.3V or
2.5V host bus, directly to 5V or 3.3V DRAMs, and directly to the 5V or
3.3V PCI bus.  The 430TX also interfaces directly to  the 3.3V or 5.0V
TAGRAM and 3.3V Cache.

The MTXC works  with the PCI IDE/ISA Accelerator  4 (PIIX4). The PIIX4
provides the PCI-to-ISA/EIO bridge functions along with other features
such  as  a  fast  IDE  interface  (PIO  mode  4  and  Ultra  DMA/33),
Plug-n-Play port, APIC interface, PCI 2.1 Compliance. SMBUS interface,
and Universal Serial Bus Host Controller functions.  

DRAM Interface
The DRAM  interface is a 64-bit  data path that  supports Standard (or
Fast) Page  Mode (FPM), Extended  Data Out (EDO) and  Synchronous DRAM
(SDRAM)  memory. The  DRAM controller  inside the  MTXC is  capable of
generating  3-1-1-1 for posted  writes for  any type  of DRAM  that is
used. While  read performance is  6-1-1-1 for SDRAM, 5-2-2-2  for EDO,
and 6-3-3-3 tor FPM.

The  DRAM interface  supports  4 Mbytes  to  256 Mbytes  with six  RAS
lines. The MTXC  supports 4-Mbit, 16-Mbit, and 64-Mbit  DRAM and SDRAM
technology.   both  symmetrical  and   asymmetrical.  Parity   is  not
supported, and  for loading reasons, x32  and x64 SIMMs/DlMMs/SO-DIMMs
should be used.

Second Level Cache
The second  level cache is  direct mapped and supports  both 256-Kbyte
and  512-Kbyte SRAM configuration  using Pipeline  Burst SRAM  or DRAM
Cache SRAM. The  Cache performance is 3-1-1-1 for  line read/write and
3-1-1-1-1-1-1-1 for  back to back reads that  are pipelined. Cacheless
configuration is also supported.

PCI Interface
The PCI  interface is 2.1  compliant and supports  up to four  PCI bus
masters in addition to the PIIX4 bus master requests.

Datapath and Buffers
The  MTXC contains  three sets  of  data buffers  for optimizing  data
flow. A five QWord deep  DRAM write buffer is provided for CPU-to-DRAM
writes,   second   level    cache   write   backs,   and   PCI-to-DRAM
transfers. This  buffer is  used to achieve  3-1-1-1 posted  writes to
DRAM and also provides DWord merging and burst merging for CPU-to-DRAM
write cycles. In addition, an extra line of buffering is provided that
is combined  with the  DRAM Write  Buffer to supply  an 18  DWord deep
buffer for PCI to main memory  writes. A five DWord buffer is provided
for  CPU-to-PCI writes  to  help maximize  the  bandwidth for  graphic
writes to  the PCI  bus. Also, five  QWords of prefetch  buffering has
been added to the PCI-to-DRAM read path that allows up to two lines of
data to be prefetched at an x-2-2-2 rate. The MTXC interfaces directly
to the Host and DRAM data bus.

Power Management Features
The MTXC  implements extensive power management  features. The CLKRUN#
feature  enables  controlling of  the  PCI  clock (on/off).  The  MTXC
supports  POS.  STR,  STD,  and Soft-off  suspend  states. SUSCLK  and
SUSSTAT1# signals are  used for implementing Suspend  Logic.  The MTXC
supports  two SMRAM  modes;  Compatible SMRAM  (C_SMRAM) and  Extended
SMRAM  (E_SMRAM).   The  C_SMRAM  is  the  traditional  SMRAM  feature
implemented  in Intel  PCIsets.  The  E_SMRAM  is a  new feature  that
supports writeback cacheable  SMRAM space up to 1 Mbytes.  In order to
minimize the  idle power,  the internal  clock in  MTXC is  turned off
(gated off) when there is no activity on the Host and PCI Bus.
