6 Introduction
Intel® Pentium® 4 Processor
The NuPRO-842 is a full-sized single board computer (SBC) that
supports a single mPGA478 Intel® Pentium® 4 processor or a
478-pin Micro Flip-Chip Pin Grid Array (Micro-FCPGA) Mobile
Intel® Pentium® 4 Processor – M.
The Pentium 4 processor runs at a core speed of up to 3.06GHz
and the Mobile Intel® Pentium® 4 Processor – M runs at a core
speed of up to 2.4Ghz. The 845GV chipset keeps the FSB opera-
tion at 400/533 MHz (auto-selected).
Intel Pentium 4 Processor and Mobile Intel Pentium 4 Proces-
sor-M have an on-die 512kB L2 Advanced Transfer Cache (ATC).
The on-die cache has a 256-bit data bus from the processor core.
The design for using Pentium 4 processor required an upgraded
Voltage Regulator Module circuit implementation (VRM 9.0) to
handle tighter voltage tolerances.
The Intel® 845GV Graphics Chipset Memory Controller
Hub (GMCH)
The central hub for all data passing through core system elements
is through the Intel 845GV Graphics Chipset Memory Controller
Hub. To balance the performance offered by the processor and
memory interfaces, the GMCH allows several high-bandwidth I/O
configuration options. This chipset delivers balanced,
high-throughput system performance for dual processor server
platforms.
The Intel® 82801DB I/O Controller Hub 4 (ICH4)
Connection to the MCH is done through a point-to-point Hub Inter-
face 1.5 connection. The ICH4 provides legacy I/O interfaces
through integrated features including a two-channel Ultra ATA/100
bus master IDE controller and an USB controller for two USB
ports. The ICH4 also offers an integrated System Manageability
Bus 2.0 (SMBus 2.0) controller, as well as a PCI 2.2-compliant
interface.
