***Info:
The Intel 430VX PCIset consists of the 82437VX System Controller
(TVX), two 82438VX Data Paths (TDX), and the PCI ISA IDE Xcelerator
(PIIXS). The PCIset 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 TVX integrates the cache and main memory DRAM control
functions and provides bus control for transfers between the CPU,
cache, main memory, and the PCI Bus. The second level (L2) cache
controller supports a write-back cache policy for cache sizes of 256
Kbytes and 512 Kbytes. Cacheless designs are also supported. The cache
memory can be implemented with standard, pipelined burst, 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 TVX's DRAM
controller, five rows are supported for up to 128 Mbytes of main
memory. The Shared Memory Buffer Architecture (SMBA) 2-wire interface
allows a graphics controller to use an area of system memory as its
frame buffer. The Intel 430VX PCIset has been enhanced through
additional buffers, programmable timers, and burst and DWord merging
and optimized DRAM timings to maintain a high level of performance
when used in a SMBA environment. Using the snoop ahead feature, the
TVX allows PCI masters to achieve full PCI bandwidth. The TDXs provide
the data paths between the CPU/cache, main memory, and PCI. For
increased system performance. the TDXs contain read prefetch and
posted write buffers.
1.0. ARCHITECTURE OVERVIEW OF TSC/TDP
The Intel 430VX PCIset (Figure 1) [see datasheet] consists of the
82437VX System Controller (TVX), two 82438VX Data Path (TDX) units,
and the PCI IDE ISA Xcelerator (PIIXS). The TVX and two TDXs form a
Host-to-PCI bridge. The PIIX3 is a multi-function PCI device
providing a PCI-to-ISA bridge, a fast IDE interface, an APIC
interface, and a host/hub controller for the Universal Serial Bus
(USB). The PIIX3 also provides power management.
The two TDXs provide a 64-bit data path to the host and to main memory
and provide a 16-bit data path (PLINK) between the TVX and TDX. PLINK
provides the data path for CPU to PCI accesses and for PCI to main
memory accesses. The TVX and TDX bus interfaces are designed for 3V
and 5V busses. The Intel 430VX PCIset connects directly to the Pentium
processor 3V host bus; The Intel 430VX PCIset connects directly to 5V
or 3V main memory DRAMs; and the TVX connects directly to the 5V PCI
Bus.
The TVX and TDX interface with the Pentium processor host bus, a
dedicated memory data bus, and the PCI bus. The Intel 430VX PCIset
implements a Shared Memory Buffer Architecture (SMBA) handshake 2-wire
protocol that allows a graphics controller to use a portion of system
memory as its frame buffer region. In addition, the PLINK bus is used
to connect the PCI bus with the TDX, through the TVX (see Figure
1). [see datasheet]
DRAM Interface
The DRAM interface is a 64-bit data path that supports Standard Page
Mode (SPM), Extended Data Out (EDO), and Synchronous DRAM (SDRAM)
memory. The DRAM interface supports 4 Mbytes to 128 Mbytes of system
memory with five RAS lines and also supports symmetrical and
asymmetrical addressing for 512Kx32, 1Mx32, 2Mx32, and 4Mx32 deep SIMM
modules (single- and double-sided). The TVX supports SDRAM 1Mx64,
2Mx64, and 4Mx64 deep DIMM modules (asymmetrical single- and
double-sided). The Intel 430VX PCIset does not support parity and
requires that x32 and x64 SIMMs/DIMMs be used.
Second Level Cache
The TVX supports a write-back cache policy providing all necessary
snoop functions and inquire cycles. The second level cache is direct
mapped and supports both a 256-Kbyte or 512-Kbyte SRAM configuration
using pipelined burst, DRAM Cache, or standard SRAMs. DRAM Cache is a
DRAM based cache alternative to pipelined burst SRAM. Its pinout is a
superset of pipeline burst and conforms to the standard pipeline burst
footprint. One chipset signal (KRQAK), two system signals (H/WR# and
RESET#), and one DRAM Cache specific signal (M/S#) are the only signal
differences between pipeline burst SRAM and DRAM Cache. The Pipeline
burst or DRAM Cache configuration performance is 3-1-1-1 for
read/write cycles; back-to-back reads can maintain a 3-1-1-1-1-1-1-1
transfer rate.
TDX
Two TDXs create a 64-bit CPU memory data path. The TDXs also interface
to the 16-bit PLINK inter-chip bus on the TVX for PCI tran-
sactions. The combination of the 64-bit memory path and the 16-bit
PLINK bus make the TDXs a cost effective solution, providing optimal
CPU-to-main memory performance, while maintaining a small package
footprint (100 pins each).
PCI Interface
The PCI interface is 2.1 compliant and supports up to four PCI bus
masters in addition to the PIIX3 bus master requests. The TVX and TDXs
together provide the interface between PCI and main memory;
however only the TVX connects to the PCI bus.
Buffers
The TVX and TDXs together contain three sets of buffers for Optimizing
data flow. A DRAM write buffer is provided for CPU-to-main memory
writes, second level cache write-back cycles, and PCI-to-main memory
transfers. This buffer is used to achieve 3-1-1-1 posted writes to
main memory, and also provides DWord merging and burst merging for CPU
to main memory write cycles. Buffering is provided for PCI-to-main
memory writes. A buffer is provided for CPU-to-PCI writes to maximize
the bandwidth for graphic writes to the PCI bus in a non-SMBA
system. In addition, PCI-to-main memory read pre-fetch buffering
permits up to two lines of data to be prefetched at an x-2-2-2 rate.
Shared Memory Buffer Architecture (SMBA)
The Intel 430VX PCIset provides a hardware interface that allows a
graphics controller to access an area of system memory as a frame
buffer. This reduces system cost by eliminating the need to have
separate memory for the graphics subsystem. Two signals are used to
arbitrate ownership of DRAM (DRAM address and control signals). The
Intel 430VX PCIset has been enhanced as follows to maintain a high
level of performance when used in a SMBA environment:
o Buffering for improved CPU and PCI posting and PCI pre-fetching
o Programmable timers to maximize performance and establish a balance
between the graphics/controller and the system (regulates read and
write accesses to DRAM)
o Burst merging and DWord merging for efficient DRAM writes
o Optimized DRAM Read timings
System Clocking
The processor, secondary cache, main memory subsystem, and PLINK bus
all run synchronously to the host clock. The host clock frequencies
supported are 50 MHz, 60 MHz. and 66 MHz. The PCI clock runs
synchronously at half the host clock frequency. The TVX and TDXs have
a host clock input and the TVX has a PCI clock input. These clocks
come from an external source and have a maximum clock skew requirement
with respect to each other.
