4.4System Processor (CPU)

The FIC A360 runs on Intel Pentium-III based on FC-PGA packaging. It supports CPU with up to 1GHz clock speed rating. The processor operates in conjunction with the RAM and ROM memory and the system control logic (e.g. VIA Twister) to process software instructions (BIOS, Windows, and Applications).

4.4.1Intel Pentium-III Features

Using Intel’s advanced 0.18 micron process technology, the Intel mobile Pentium III processor is offered at speeds of 700MHz to 1GHz while still offering lower power for long battery life. Other performance advancements include the addition of new Internet Streaming SIMD instructions, the 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 Conserved Performance. Maximum Performance mode provides near desktop performance and runs at 700, 750, 800 and 850 MHz. Conserved Performance mode provides the best balance between performance and battery life and operates at a lower frequency of 550, 600, 650, 700 MHz. You can check the table of two performance modes as following.
