***Notes:...
***Info:
The Intel 430HX PCIset consists of the 82439HX System Controller (TXC)
and the 82371SB PCI I/O IDE Xcelerator (PIIX3). The TXC is a
single-chip host-to-PCI bridge and provides the second level cache
control and DRAM control functions. 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 is implemented with synchronous pipelined burst SRAMs. An
external Tag RAM is used for the address tag and an internal Tag RAM
for the cache line status bits. The TXC provides a 64/72-bit data path
to main memory and memory sizes up to 512 Mbytes. The DRAM controller
provides eight rows and optional DRAM Error detection/correction or
parity. The TXC‘s optimized PCI interface allows the CPU to sustain
the highest possible bandwidth to the graphics frame buffer at all
frequencies. Using the snoop ahead feature, The TXC allows PCI masters
to achieve full PCI bandwidth. For increased system performance, the
TXC contains read prefetch and posted write buffers.
1.0. ARCHITECTURE OVERVIEW
The TXC interfaces with the Pentium processor host bus, a dedicated
memory data bus, and the PCI bus (Figure 1) [see datasheet]. The TXC
connects directly to the Pentium processor 3V host bus, directly to 5V
or 3V DRAMs. and directly to the 5V PCI bus. The Intel 430HX PCIset
consists of the 82439HX TXC and the PCI IDE/ISA Xcellerator (PIIXS)
components. PIIXS provides the PCI-to-ISA bridge functions along with
other features such as a fast IDE interface, Plug'n-Play port, APIC
interface, Universal Serial Bus (USB) and PCI 2.1 Compliance
operation.
Data Flow
Processor cycles are sent directly to the second level cache with
control for the second level cache provided by the TXC. All other
processor cycles are sent to their destination (DRAM, PCI or internal
TXC configuration space) via the TXC. PCI Master cycles are sent to
main memory through the TXC. The TXC performs snoop or inquire cycles
using the host bus.
DRAM Interface
The DRAM interface is a 64/72-bit data path that supports both
standard page mode and Extended Data Out (EDO) memory. The DRAM
interface supports 4 Mbytes to 512 Mbytes with 8 RAS lines and also
supports symmetrical and asymmetrical addressing for 1M, 2M, and 4M
deep SIMMs and symmetrical addressing for 16-Mbyte deep SIMMs.
Second Level Cache
The TXC 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 SRAMs. The burst 256-Kbyte configuration
performance is 3-1-1-1 for read/write cycles; pipelined back-to-back
reads can maintain a 3-1-1-1-1-1-1-1 transfer rate. An optional mode
extends the DRAM L2 cacheability range to 512 Mbytes.
PCI Interface
The PCI interface is 2.1 compliant and supports up to 4 PCI bus
masters in addition to the PIIX3 bus master requests. The PCI-to-DRAM
interface can reach a 112 Mbyte/sec transfer rate for reads and 121
Mbytes/sec for writes.
Data Path and Buffers
The TXC data path is optimized for minimum latency and maximum
throughput operation from both the CPU and PCI masters. The TXC
contains two physical sets of buffers for optimizing data flow. A
6-DWord buffer is provided for CPU-to-PCI writes that helps maximize
the graphic writes to PCI bandwidth. An 8-QWord deep merging memory
buffer is provided that is used for CPU-to-main memory writes,
write-back cycles (Posted at 3111), PCI-to-main memory write
posting. and PCI-from-main memory read prefetching.
Error Detection and Correction
Parity or error correction are software configurable options (parity
is the default). The ECC mode provides single-error correction,
double-error detection, and detection of all errors confined to a
single nibble for the DRAM memory subsystem.
