Processor features
Processor features 1. SMM (System Management Mode) SMM is a power management circuitry. This circuitry enables processors to conserve energy use and lengthen battery life. This was introduced initially in the Intel 486SL processor. SMM circuitry is integrated into the physical chip but operates independently to control the processor’s power use based on its activity level. It enables the user to specify time intervals after after which the CPU will be partially or fully powered down. It also supports the suspend/resume feature that allows for instant power on and power off, used mostly with laptop PCs. These settings are typically controlled via system BIOS settings. While initially used mainly for power management, SMM ...
