1.3.2 Processor

The cPB-4612 uses the Mobile Pentium M in a micro FCBGA package. The 1MB or 2MB on-die transfer L2 cache is integrated with the CPU, eliminating the need for separate components and improving performance. The FCBGA package Pentium M processor also operates with a 400 MHz Processor Side Bus for very fast access to memory and data.

1.3.3 Chipset

The Intel 855GME chipset consists of two controller hubs. The 855GME Memory Controller Hub (MCH) supports a 400MHz system bus, DDR200/266/333 memory, and an integrated graphics solution w/Intel Extreme Graphics 2 technology. The 6300ESB I/O Controller Hub (ICH4) makes a direct connection to the memory for faster access to peripherals. It provides the features and bandwidth required for applied computing-usage models. The following is a list of features of the 855GME chipset:

•Designed, validated, and optimized for the Intel Pentium M with NetBurst™ micro-architecture using proven and established building blocks

•400MHz system bus delivers a high-bandwidth connection between the Intel Pentium M and the platform, providing 3x the bandwidth over platforms based on Intel® Pentium® III processors

•USB controllers provide high performance peripherals with 480Mbps of bandwidth. This results in a significant increase over previous integrated 1-4 port hubs at 12Mbps

•Dual UARTs

•Serial ATA

•64bit/66Mhz PCI-X bus

•32bit/33Mhz PCI bus

•Dual Ultra ATA/100 controllers, coupled with the Intel® Application Accelerator - a performance software package - support faster IDE transfers to storage devices

•The Intel® Application Accelerator software provides additional performance over native ATA drivers. The Intel Application Accelerator improves system performance by improving I/O transfer rates and enables faster O/S load time resulting in accelerated boot times

•Embedded lifecycle support

1.3.4 PCI-to-PCI Bridge

The cPB-4612 has a 64bit/66Mhz PCI-X bridge to the CompactPCI backplane. The bridge will configure itself as a transparent bridge when the board is in a system slot, so that the cPB-4612 can be the system host. If the cPB-4612 is placed in a peripheral slot, the bridge configures itself as a non-transparent bridge, and will show up as a PCI device to the host. This allows use of the board in either a system or peripheral slot.
