4.4 System Processor (CPU)
4.44.4
The FIC A440 runs on Intel Mobile Pentium-III based on Socket 370 FCPGA packaging. It
supports CPU with up to 850 MHz clock speed rating. The processor operates in conjunction
with the RAM and ROM memory and the system control logic (e.g. VIA VT8601) to process
software instructions (BIOS, Windows, and Applications).

4.4.1 Intel Mobile Pentium-III Features
Using Intel’s advanced 0.18 micron process technology, the Intel mobile Pentium III
processor is offered at speeds of 400MHz, 450MHz, and 500MHz while still offering lower
power for long battery life. Other performance advancements include the addition of new
Internet Streaming SIMD instructions, an advanced transfer cache architecture, and a
processor system bus speed of 100MHz.
Intel Mobile Pentium III processor featuring Intel SpeedStep technology is the next dramatic
step towards achieving near desktop performance. This exciting new processor has two
performance modes and allows real-time dynamic switching of the voltage and frequency
between the modes. This occurs by switching the bus ratios, core operating voltage, and core
processor speeds without resetting the system.
There are two performance modes offered, Maximum Performance and Battery Optimized
Performance. Maximum Performance mode provides near desktop performance and runs at
600 or 650MHz. Battery Optimized Performance mode provides the best balance between
performance and battery life and operates at a lower frequency of 500MHz.

Hardware Functional Overview
The integrated L2 cache is designed to help improve performance, and it complements the
system bus by providing critical data faster and reducing total system power consumption.
The mobile Pentium III processor’s 64-bit wide Gunning Transceiver Logic (GTL+) system
bus provides a glue-less, point-to-point interface for an I/O bridge/memory controller, and is
compatible with the 440BX AGPset, 440ZX-M AGPset, and the 440MX Chipset.
