The CPU power states C0–C3 are defined as follows: C0 is the operating state. C1 (often known as Halt) is a state where the processor is not executing instructions, but can return to an executing state essentially instantaneously. All ACPI-conformant processors must support this power state.
Control and Status Register (CSR) are auxiliary registers in many CPUs and many microcontrollers that are used for reading status and changing configuration, in contrast to the integer and sometimes floating registers which are used for computation. The control and status registers are often described by a register map.
A control register is a processor register that changes or controls the general behavior of a CPU or other digital device. Common tasks performed by control registers include interrupt control, switching the addressing mode , paging control, and coprocessor control.
APM Standby: Most devices are in their low-power state, the CPU is slowed or stopped, and the system state is saved. The computer can be returned to its former state quickly (in response to activity such as the user pressing a key on the keyboard). APM Suspend: Most devices are powered off, but the system state is saved. The computer can be ...
Power gating is a commonly used circuit technique to remove leakage by turning off the supply voltage of unused circuits. Power gating incurs energy overhead; therefore, unused circuits need to remain idle long enough to compensate this overheads. A novel micro-architectural technique [10] for run-time power-gating caches of GPUs saves leakage ...

The reset vector is a pointer or address, where the CPU should always begin as soon as it is able to execute instructions. The address is in a section of non-volatile memory (such as BIOS or Boot ROM ) initialized to contain instructions to start the operation of the CPU, as the first step in the process of booting the system containing the CPU.
