Rapid Execution Engine:
The Integer Arithmetic Logic Unit (ALU) clocked at twice the frequency provides
four ALUs of computing bandwidth and allows lower latency execution increasing
performance for certain integer operations.
4.4.2 Mobile Intel Pentium 4 Processor – M Features
The new mobile Intel® Pentium® 4 Processor-M is Intel's next generation processor for full-
size and thin-and-light mobile PCs offered at speeds up to 1.70GHz. Using Intel's advanced
0.13-micron process technology, which features the smallest production transistors in the
world, the Mobile Pentium 4 Processor-M enables higher processor frequency at lower
power. Key performance features of the mobile Intel® Pentium® 4 Processor - M includes
512kb on-die L2 Cache and Intel NetBurst™ Micro-Architecture, consisting of a 400 MHz
processor system bus, Hyper Pipelined Technology, new Execution Trace Cache, Rapid
Execution Engine, and 144 new Streaming SIMD instruction extensions. This advanced
mobile processor, together with the Mobile Intel® 845MP chipset, provides a more stable
platform and OS environment, decreasing deployment time and reducing qualification,
support and maintenance costs.
The mobile Intel® Pentium® 4 Processor - M also features Intel's low power technologies
including support for Enhanced Intel SpeedStep™ technology, which enables real-time
dynamic switching of the voltage and frequency between two performance modes based on
CPU demand. The processor also features a new ultra low power alert state called Deeper
Sleep, which enables the processor to retain critical data at very low voltages and minimizes
power dissipation when the processor is not active. These low power features extend battery
life, increasing the efficiency and productivity of mobile PC users.
Features summary of the mobile Intel® Pentium® 4 Processor - M:
• CPU Clock Speeds up to 1.7 GHz
- Fastest Mobile Intel® processor speed, outstanding performance for demanding
applications Stores twice the data of previous mobile processors in on-chip memory for
quick access and fast response
• Advanced Transfer Cache: 512 KB On-Die Full-Speed Level 2 (L2) cache
- Stores twice the data of previous mobile processors in on-chip memory for quick access
and fast response
• 400 MHz Processor System Bus
- 3X faster bus bandwidth (3.2GB/s) than P6 (1 GB/s) for moving data between memory,
I/O devices, graphics, and other bus devices
• Execution Trace Cache
- New innovative cache stores 12K of decoded instructions allowing quicker response and
improved cache efficiency by reducing the time required to fetch and decode instructions
• Hyper-pipelined Technology
- Twice the pipeline length from previous Intel® architecture with 20 stages for storing
instructions and data which allows for higher frequency scalability and performance
• Second-Generation Streaming SIMD Extensions (SSE2)
- 144 new instructions providing software developers with new capabilities for
accelerating video, multimedia, 3D, imaging, and encryption. These new instructions can
