摘要： A data processing system features a processor, random access memory (RAM), flash memory, a disk drive, an operating system (OS), and platform software. The platform software is capable of intercepting an attempt by the OS to read a storage location of the disk drive during a process of transitioning the data processing system from an inactive mode to an active mode. In response to intercepting the attempt by the OS to read the disk drive, the platform software may automatically determine whether the storage location for the read corresponds to a disk area reserved for power state transition data. If the storage location corresponds to the area reserved for power state transition data, the platform software may automatically read data from the flash memory instead of the disk drive, and pass that data to the OS. Other embodiments are described and claimed.

摘要： A filtering system for instruction segments determines whether a new instruction segment satisfies a predetermined filtering condition prior to storage. If the instruction segment fails the filtering condition, the new instruction segment is not stored. Various filtering conditions are available; but all filtering conditions test to determine whether it is more likely than not that a new instruction segment will be reused by the execution unit in the future.

摘要： A plurality of global registers are provided on the microprocessor chip. One of a global registers is a frame pointer register containing the current frame pointer, and the remainder of the global registers are available to a current process as general registers. A plurality of floating point registers are also provided for use by the current process in execution of floating point arithmetic operations. A register set pool made up of a plurality of register sets is provided, each register set being comprised of a number of local registers. When a call instruction is decoded, a register set of local registers from the register set pool is allocated to the called procedure, and the frame pointer register is initialized. When a return instruction is decoded, the register set is freed for allocation to another procedure called by a subsequent call instruction. If the register set pool is depleted a register set associated with a previous procedure is saved in the main memory, and that register set is allocated to the current procedure. The local registers in a register set associated with a procedure contain linkage information including a pointer to the previous frame and an instruction pointer, thus enabling most call and return instructions to execute without needing any references to off-chip memory.
