1.1 Introduction

The MIC-3392 is a high performance, power efficient CompactPCI single-board com-

puter based on the Intel Core 2 Duo and Core Duo microprocessors. The MIC-3392

delivers breakthrough energy-efficient performance for CompactPCI platforms. The

Intel Core 2 Duo provides enhanced energy-efficient performance to help equipment

manufacturers optimally balance processing capabilities within power and space con-

straints. The advanced smart cache of Core Duo dynamically allocates the shared L2

cache across cores and optimizes use of memory subsystem bandwidth to acceler-

ate out-of-order execution. A prediction mechanism reduces the time in-flight instruc-

tions have to wait for data. The new pre-fetch algorithms move data from system

memory into fast L2 cache in advance of execution.

The Core Duo combines the benefits of two high-performance execution cores with

intelligent power management features to deliver significantly greater performance

per watt over previous Intel processors. The two execution cores share a high-perfor-

mance, power-optimized 667 MHz front-side bus to access the same system mem-

ory. To save power, address and data buffers are turned off when there is no activity.

The MIC-3392 maximizes I/O throughput with PCI Express (PCIe) technology. It sup-

ports up to 4 GB of 667 MHz DDR2 memory provided by a combination of SO-DIMM

and soldered DRAM (6.4 GB/sec throughput). It supports a fast Serial-ATA interface

to an on-board hard drive or CompactFlash socket. The MIC-3392 is available in sin-

gle or dual PMC variants with differing I/O combinations as listed in the table below.

Note! The OS may report around 3GB of system memory when 4GB is

installed. Because the Intel 82945GME Graphics and Memory Control-

ler Hub (GMCH) does not remap APIC or PCI Express memory space,

when system memory is populated with 4GB, some physical memory is

non-addressable and remains unusable by the system.
