Overview
The Intel® Core™ 2 Duo processor (Merom) is the second-generation dual-core processor for
portable computers, delivering up to a 25 percent performance gain over the Intel Core Duo
processor (Yonah). It is part of Intel's refresh of its mobile technology offering, code-named
Napa. Here is a quick list of features Merom has to offer:
Intel Wide Dynamic Execution
Intel Intelligent Power Capability
Intel Advanced Smart Cache
Intel Smart Memory Access
Intel Advanced Digital Media Boost
Intel Wide Dynamic Execution
Dynamic execution is a combination of techniques (data flow
analysis, speculative execution, out of order execution, and
super scalar) that Intel first implemented in the P6
microarchitecture used in the Pentium® Pro processor, Pentium
II processor, and Pentium III processors.
Now with the Intel Core microarchitecture, Intel significantly
enhances this capability with Intel Wide Dynamic Execution. It
enables delivery of more instructions per clock cycle to improve
execution time and energy efficiency. Every execution core is
33 percent wider than previous generations, allowing each core
to fetch, dispatch, execute, and retire up to four full instructions
simultaneously.
Intel Wide Dynamic Execution also includes a new and
innovative capability called Macro-Fusion. Macro-Fusion
combines certain common x86 instructions into a single
instruction for execution.
Combined, Intel Wide Dynamic Execution increases instruction execution efficiency, thus increasing performance and
energy efficiency.
Intel Intelligent Power Capability
Intel Intelligent Power Capability is designed to reduce power consumption and design requirements. This feature manages
the runtime power consumption of all the processor's execution cores. The result is excellent energy optimization enabling
Intel Core microarchitecture to deliver more energy-efficient performance for desktop PCs, mobile PCs, and mainstream
servers.
Intel Advanced Smart Cache
The Intel Advanced Smart Cache is a multicore optimized cache that significantly reduces latency to frequently used data,
thus improving performance and efficiency by increasing the probability that each execution core of a multicore processor
can access data from a higher-performance, more efficient cache subsystem.
