Introduction
The cPCI-3840 is designed to be a high performance dual slot 3U
CompactPCI CPU Module. It features a single Intel® Pentium® M
processor with 1MB L2 cache in a 478-pin Micro-FCPGA package,
and is validated with the Intel® 855GME chipset that supports
144-bit wide PC2100/2700 (266/333 MHz) registered ECC DDR
DIMM up to a maximum of 2GB. The cPCI-3840 also features the
Intel® 82546EB Dual Port Gigabit Ethernet Controller and sup-
ports one ATA33/66/100 IDE channel, one Compact Flash type I/II
connector, and 2 ports SATA for high volume storage applications.
The Intel® Pentium® M is a high performance, low power mobile
processor with several micro-architecture enhancements over
existing Intel Mobile processors. Intel® Pentium® M supports
Intel® Architecture with Dynamic Execution, on-die primary 32-KB
instruction cache and 32-KB write-back data cache, on-die 1-MB
second level cache with Advanced Transfer Cache Architecture,
Advanced Branch Prediction and Data Prefetch Logic, Streaming
SIMD Extensions 2 (SSE2), a 400-MHz Source-Synchronous pro-
cessor system bus, and Advanced Power Management features
including Enhanced Intel® SpeedStep® technology.
The Intel® Pentium® M processor system bus supports AGTL+
bus driver technology with integrated GTL termination resistors,
(gated AGTL+ receivers for reduced power), 32-bit AGTL+ bus
addressing (no support for 36-bit address extension), 400MT/s
BPSB (100MHz), 2X address, 4X data, and 12 deep in-order
queues.
The Intel® 855GME chipset north bridge contains a Graphics
Memory Controller Hub (GMCH) component for embedded plat-
forms. The GMCH provides the processor interface, system mem-
ory interface (DDR SDRAM), hub interface, CRT, and a DVO
interface. The GMCH also supports 128-MB, 256-MB, and 512-
MB memory technologies, 16 simultaneous open pages, and 64-
bit data interface (72-bit with ECC).
Furthermore, the 855GME features a 350 MHz integrated 24bit
RAMDAC supporting analog display with pixel resolution up to
1600x1200 at 85Hz and 2048x1536 at 75Hz, dual independent
display pipe supporting concurrent or simultaneous display on
