4.4 System Processor (CPU)
The FIC MD02 runs on Intel Dothan based on uFCPGA packaging. It supports CPU with
1.8 GHZ clock speed rating. The processor operates in conjunction with the RAM and
ROM memory and the system control logic to process software instructions (BIOS,
Windows, and Applications).
Intel Pentium M Features
The Intel® Pentium® M processor is a high performance, low power mobile processor with
several micro-architectural enhancements over existing Intel mobile processors.
The following list provides some of the key features on this processor:
• Supports Intel® Architecture with Dynamic Execution
• High performance, low-power core
• On-die, primary 32-kbyte instruction cache and 32-kbyte write-back data cache
• On-die, 1-MByte second level cache with Advanced Transfer Cache Architecture
• Advanced Branch Prediction and Data Prefetch Logic
• Streaming SIMD Extensions 2 (SSE2)
• 400-MHz, Source-Synchronous processor system bus
• Advanced Power Management features including Enhanced Intel® SpeedStep®
technology
• Micro-FCPGA and Micro-FCBGA packaging technologies
The Intel Pentium M processor is manufactured on Intel’s advanced 0.13 micron process
technology with copper interconnect. The processor maintains support for MMX™
technology and Internet Streaming SIMD instructions and full compatibility with IA-32
software. The high performance core features architectural innovations like Micro-op
Fusion and Advanced Stack Management that reduce the number of micro-ops handled by
the processor. This results in more efficient scheduling and better performance at lower
power. The on-die 32-kB Level 1 instruction and data caches and the 1-MB Level 2 cache
with Advanced Transfer Cache Architecture enable significant performance improvement
over existing mobile processors. The processor also features a very advanced branch
prediction architecture that significantly reduces the number of mispredicted branches. The
processor’s Data Prefetch Logic speculatively fetches data to the L2 cache before an L1
cache requests occurs, resulting in reduced bus cycle penalties and improved performance.
The Streaming SIMD Extensions 2 (SSE2) enable break-through levels of performance in
multimedia applications including 3-D graphics, video decoding/encoding, and speech
recognition.The new packed double-precision floating-point instructions enhance
performance for applications that require greater range and precision, including scientific
and engineering applications and advanced 3-D geometry techniques, such as ray tracing.
The Intel Pentium M processor’s 400-MHz processor system bus utilizes a split-transaction,
deferred reply protocol. The 400-MHz processor system bus uses Source-Synchronous
Transfer (SST) of address and data to improve performance by transferring data four times
per bus clock (4X data transfer rate, as in AGP 4X). Along with the 4X data bus, the
address bus can deliver addresses two times per bus clock and is referred to as a “double-
clocked” or 2X address bus.Working together, the 4X data bus and 2X address bus
provide a data bus bandwidth of up to 3.2 Gbytes/second. The processor system bus uses
Advanced Gunning Transceiver Logic (AGTL+)signal technology, a variant of GTL+
signalling technology with low power enhancements.
The processor features Enhanced Intel SpeedStep technology, which enables real-time
