ICC - Processor current.
RLL - Load line impedance: Defined as the ratio of voltage droop/current step. This is the load line slope. In this document, the load line is referenced at the
socket unless otherwise stated.
TOB - Vcc regulation tolerance band: Defines the voltage regulator s - voltage variation across temperature, manufacturing variation, and age factors. Must be ensured by design through component selection. Defined at processor maximum
current and maximum VID levels.
VCC - Processor core voltage.
VID - Voltage IDentification: A code supplied by the processor that determines the reference output voltage to be delivered to the processor Vcc lands. At zero
amperes and the tolerance band at - , VID is the voltage at the processor.
