4.2.1 System Processor
The System Processor function for the notebook is implemented on the Motherboard
in the form of an Intel Pentium P54-C Superscalar 586 Processor Chip. The processor
operates in conjunction with RAM and ROM Memory and other control logic to process
software instructions (BIOS, DOS, Windows, and applications). The processor
communicates with the hard disk drive and the memory components using high speed
busses.
The Processor also interacts with other hardware logic to provide the power savings
features for the notebook. These features include controlling CPU clock speeds,
reducing clock speeds whenever possible (e.g. when performing floppy disk drive
accesses), powering down unused devices, etc.
