摘要： Various embodiments are generally directed recurringly cycling the driving of a platter media of a hard drive with a motor, allowing rotation of the platter media to slow only to a threshold rotational speed to balance power conservation with delays in accessing data. A method comprises driving platter media of a hard drive to rotate at a selected normal rotational speed, retrieving data stored on the platter media when the platter media rotates at the normal rotational speed, ceasing to drive the platter media to rotate to allow the platter media to rotate under rotational inertia imparted to the platter media, monitoring a current rotational speed of the platter media, and resuming driving the platter media to rotate based on the current rotational speed falling to a lower threshold rotational speed selected to be less than the normal rotational speed. Other embodiments are described and claimed.

摘要： An embodiment of the present invention is a technique to dynamically swap processor cores. A first core has a first instruction set. The first core executes a program at a first performance level. The first core stops executing the program when a triggering event occurs. A second core has a second instruction set compatible with the first instruction set and has a second performance level different than the first performance level. The second core is in a power down state when the first core is executing the program. A circuit powers up the second core after the first core stops executing the program such that the second core continues executing the program at the second performance level.

摘要： A bus utilization detection circuit and method. An input is configured to be coupled to a bus to detect bus events. A circuit coupled to the input determines a number of bus events during a first sample period to indicate a percent bus utilization. If the number of bus events during the first sample period meets a first predetermined threshold value, then an activity event is generated. In another embodiment, an activity event is generated only if during a second sample period, the number of first sample periods for which the percent bus utilization meets the first threshold value meets a second threshold value.

摘要： A method and apparatus for operating an integrated in a reduced-power consumption state are described. The apparatus comprises power-reduction logic which, to place the integrated circuit in the reduced-power consumption state, gates a clock signal to both first and second sets of functional units within the integrated circuit. The first set of functional units is distinguished in that it is required to perform cache coherency operations within integrated circuit. The apparatus includes an input which is coupled to receive a signal indicating a memory access, to a memory resource accessible by the integrated circuit, by a further device external to the integrated circuit. In response to the assertion of this signal, the power-reduction logic propagates the clock signal to the first set of functional units, to enable this set of functional units to perform a cache coherency operation which may be necessitated by the memory access by the external device.

摘要： An apparatus and method for controlling the stopping of the clock signal utilized by the processing unit of a computer system comprises the use of a novel external pin which can be enabled to initiate a sequence of events that results in the halting of the internal clock signal. The invention includes a microcode engine that responds to the/assertion of the external pin by executing a sequence of steps which stops the current instruction on an instruction boundary. A logic circuit then generates a signal that masks the clock signal produced by the system's phase-locked loop. An interrupt mechanism is also utilized to prioritize the occurrence of the external signal among other system interrupts. The interrupt mechanism insures that the processor never has its clock stopped in the middle of a bus cycle.

摘要： A novel method and apparatus to cache System Management Mode (SMM) data with other data to improve performance and reduce latency of SMM handler routines. This method and apparatus allows SMM data and non-SMM data to be distinguished in the cache without requiring extra cache bits which can add to the cost of implementation. Since SMM data and non-SMM data can coexist in the cache, there is no need for time consuming cache flush cycles when switching between the two modes. Since SMM data can be cached, performance of SMM routines are improved. This method and apparatus defines the SMRAM address range to be a range of addresses representable by the tag, but not directly corresponding to installed main memory. When accesses are made to SMRAM addresses, they are redirected to an unused portion of main memory. Protection mechanisms may be implemented to limit access to these SMRAM addresses when not in SMM.
摘要翻译：一种用于将系统管理模式（SMM）数据与其他数据进行缓存的新方法和装置，以提高性能并减少SMM处理程序的等待时间。该方法和装置允许在高速缓存中区分SMM数据和非SMM数据，而不需要增加执行成本的额外的缓存位。由于SMM数据和非SMM数据可以在高速缓存中共存，因此在两种模式之间切换时不需要耗时的高速缓存刷新周期。由于可以缓存SMM数据，因此提高了SMM例程的性能。该方法和装置将SMRAM地址范围定义为标签可表示的地址范围，但不直接对应于已安装的主存储器。当对SMRAM地址进行访问时，它们被重定向到主存储器的未使用部分。当不在SMM中时，可以实施保护机制来限制对这些SMRAM地址的访问。
