Intel Pentium 4 Processor
The Pentium 4 processor in the 478-pin package is the next
generation IA -32 processor. This processor has a number of
features that significantly increase its performance with respect to
previous generation IA -32, it includes the 400 MHz system bus, and
an execution trace cache. The hyper-pipelined technology doubles
the pipeline depth in the Pentium 4 processor in the 478-pin
package, allowing the processor to reach much higher core
frequencies (up to 2GHz). It also features the advanced transfer
cache, which is a 256 KB, on-die level 2 Cache with an increased
bandwidth over previous micro-architectures.
Memory
NuPRO-840 supports DDR SDRAM memory. The entire memory array may
be configured as either standard (un-buffered) DDR SDRAM or buffered
SDRAM. The memories speed, type and size can be determined by the
BIOS reading the DIMM presence detect bits on the SMBus (System
Management Bus). The NuPRO-840 supports up to 2GB of DDR SDRAM
memory with two 184-pin DDR DIMM sockets. The NuPRO-840 supports
2.5 Volt single-sided or double-sided DIMMs. DDR SDRAM operations up
to 200MHz are supported.
PCI-to-ISA Bridge
The NuPRO-840 features one ITE8888 PCI-to-ISA bridge. The IT8888
serves as a bridge between the PCI bus and ISA bus. The IT8888’s 32-bit
PCI bus interface is compliant with PCI Specification V2.1 and supports
both PCI Bus Master & Slave.
Special features of the ITE8888 include:
•
PCI Specification V. 2.1 compliant
•
Supports 32-bit PCI bus & up to 33 MHz PCI bus frequency
•
Single 33 MHz Clock Input
