Building the Power-Efficient PC: A Developer's Guide to ACPI Power Management
This book provides developers and integrators with practical knowledge and design techniques for building PCs that address the increasing demand for energy conservation.
TABLE OF CONTENTS Building the Power-Efficient PC: A Developer's Guide to ACPI Power Management
R-S
- RDRAM (or Rambus DRAM)
- RDRAM is a type of main system memory developed by Rambus, Inc. that uses a packetized protocol to transfer data at speeds up to 600 MHz.
- Real-time Clock (RTC)
- The RTC is a chip which can be set up to provide a computer with the correct hour, date, and year at all times after an initial setting.
- Register Grouping
- A register grouping consists of two register blocks (it has two pointers to two different blocks of registers). The fixedposition bits within a register grouping can be split between the two register blocks. This allows the bits within a register grouping to be split between two chips.
- Reserved Bits
- Some unused bits in ACPI hardware registers are designated as Reserved in the ACPI specification. For future extensibility, hardware register reserved bits always return zero, and data writes to them have no side effects. OSPM implementations must write zeros to all reserved bits in enable and status registers and preserve bits in control registers.
- Resume Latency
- Resume latency is the elapsed time from a wake event to when the system is restored to operation and executing application software instructions normally.
- Resume Well
- The portion of ACPI circuitry used for waking up the system.
- Root System Description Pointer (RSDP)
- This structure s only purpose is to provide the physical address of the RSDT. An ACPI-compatible system must provide an RSDP in the system s low address space.
- Root System Description Table (RSDT)
- The RSDT is an ACPI table with...
