摘要： A processor receives a command via a sideband interface on the processor to read processor state information, e.g., CPUID information. The sideband interface provides the command information to a microcode engine in the processor that executes the command to retrieve the designated processor state information at an appropriate instruction boundary and retrieves the processor state information. That processor information is stored in local buffers in the sideband interface to avoid modifying processor state. After the microcode engine completes retrieval of the information and the sideband interface command is complete, execution returns to the normal flow in the processor. Thus, the processor state information may be obtained non-destructively during processor runtime.

摘要： Predictions may be made regarding heat removal requirements depending on certain operational characteristics of an information processing system which have been monitored over time. A fan may be controlled based on the observed operational characteristics and based on the predictions made regarding the heat removal requirements for the system. For example, system utilization by applications may be monitored, possibly along with system performance parameters such as power level and frequency. These and other operational characteristics may be used to predict heat generation so that a fan may be controlled to anticipate temperature changes and thereby flatten temperature curves over time. This may be done in addition to monitoring the ambient temperature of the system and reacting to temperature spikes that may have already occurred.

摘要： A microcontroller has many internal peripheral devices. The peripheral devices are coupled to a scan path. A memory storage device that is external to the microcontroller is also coupled to the scan path. When commanded, data is shifted out of each device configuration register onto the scan path and stored in the external memory device. This is particularly useful for obtaining the states of each device without bringing down the application. Furthermore, configuration data stored in external memory can be loaded into the peripheral device configuration registers via the scan path. This invention also supports zero-volt suspend/resume which does not need extra software readable shadow registers which are often required in other architectures for reading back the current state of legacy registers which are read-only.

摘要： A system adds functionality to a power button where use of the power button controls the entry and exit from a diagnostic mode. The system includes an information appliance connected to a diagnostic appliance. Once an information appliance is powered up, the information appliance monitors its power button for a press which indicates a request to enter a diagnostic mode. Absent a press of the power button, the system continues to be under control of the information appliance and never enters a diagnostic mode. However, if a press of the power button is detected, the system enters a diagnostic mode. Once in a diagnostic mode the system provides an exit therefrom by interpreting a power button press as a request to exit. The window of time to make such an exit closes once the diagnostic appliance achieves communication with the information appliance. If the power button is pressed during this window of time, then the system ends its diagnostic mode and control of the system returns to the information appliance. If the power button is pressed after the window of time has closed, then the diagnostic appliance retains control of the information appliance and maintains its ability to execute diagnostic type commands thereon. The illustrative system is particularly useful when incorporated into devices with limited interface connections such as legacy-free information appliances. The system allows for a standard existing button on the information appliance to serve diagnostic purposes, avoiding the need for initializing peripherals requiring substantial execution space.
摘要翻译：系统将功能添加到电源按钮，使用电源按钮控制进入并退出诊断模式。该系统包括连接到诊断设备的信息设备。一旦信息设备通电，信息设备就会监视其按钮的电源按钮，指示进入诊断模式的请求。没有按下电源按钮，系统继续受到信息设备的控制，并且不会进入诊断模式。但是，如果检测到按下电源按钮，系统进入诊断模式。一旦进入诊断模式，系统通过解释电源按钮按钮作为退出请求来提供退出。一旦诊断设备实现与信息设备的通信，进行此类退出的时间窗口就会关闭。如果在此窗口内按下电源按钮，系统将结束其诊断模式，系统的控制返回到信息设备。如果在时间窗口关闭后按下电源按钮，则诊断设备保持对信息设备的控制，并保持其在其上执行诊断类型命令的能力。当被并入具有有限接口连接的设备（例如无遗留信息设备）中时，说明性系统特别有用。该系统允许信息设备上的标准现有按钮用于诊断目的，避免需要初始化需要大量执行空间的外设。

摘要： A computer system has multiple performance states. The computer system periodically determines utilization information for the computer system and adjusts the performance state according to the utilization information. If a performance increase is required, the computer system always goes to the maximum performance state. If a performance decrease is required, the computer system steps the performance state down to a next lower performance state.

摘要： A computing system employs an unicode driver to access and control peripheral devices by abstracting commands and status data to a level above register sets of similar but potentially incompatible peripheral devices. A unicode may be generated by an operating system or the unicode driver. Unicodes are routed by a device configuration interface that passes the unicodes between the unicode driver and peripheral devices. The peripheral devices include command decoders for performing conversion between unicodes and device-specific instructions. The use of unicode drivers eliminates duplicate driver code and simplifies device configuration for the computing system.

摘要： An integrated circuit device provides an operational set point indicator. The operational set point indicator is utilized for obtaining a plurality of operational set points. Each of the plurality of operational set points can be a pair of an operational voltage and an operational frequency for application to the integrated circuit device. The operational set point indicator can be, for example, a Schmoo Class Register, a Device Identification Register, or actual operating condition information of the integrated circuit device. The Schmoo Class Register and the Device Identification Register are utilized to identify a performance state table in memory. The actual operating conditional information can be one or more entire Schmoo Plots for the device or a subset of such information. Operational set points are used during operation of the integrated circuit device, for example, in power management applications.

摘要： A microcontroller is presented having a block of logic configurable to perform a selected logic function and to produce output signals coupled to corresponding I/O pads according to a predefined hardware interface. The microcontroller includes a central processing unit (CPU), a first set of I/O pads, and a configurable logic block (CLB) all formed upon a single monolithic semiconductor substrate. The CPU is configured to execute instructions, preferably x86 instructions. The CPU produces CPU output signals during instruction execution. The CLB is coupled between the CPU output signals and the first set of I/O pads, and is configurable to perform a logic function selected from a predefined set of logic functions. Each member of the set of logic functions has an associated hardware interface including a signal table which defines a correspondence between CLB input/output signals and members of the first set of I/O pads. The microcontroller also preferably includes a test/program core coupled to a second set of I/O pads and to the CLB. The test/program core produces programming signals in response to signals received via the second set of I/O pads. The programming signals cause the CLB to perform the selected logic function. When programmed, the CLB produces CLB output signals in response to the CPU output signals. Each of the CLB output signals is coupled to one or more of the members of the first set of I/O pads according to the hardware interface of the selected logic function.

摘要： A System Management Mode is transparent to normal system operations and dynamic RAM (DRAM) is available in the Upper Memory Block address range that is normally not accessible in many configurations. Therefore, the DRAM is advantageously used to attain System Management Mode read/write storage requirements. The System Management Mode time-multiplexes the Upper Memory Block memory-mapped address space with other non-DRAM resources in a timely manner by switching the SMM memory into the DRAM Upper Memory Block space in a "just in time" (JIT) basis. The JIT operation is achieved by latching the first memory address emitted from the CPU after SMM entry. The first memory address is designated as the top address of a memory block that extends downward into memory address space, defining an SMM memory range. All subsequent memory accesses that are addressed within the SMM memory range are directed to DRAM Upper Memory Block regardless of any other memory-mapped resources that normally reside within the same range of addresses as the SMM memory range. Upon the occurrence of an SMM resume instruction, the memory device mapping is automatically restored to the configuration existing prior to SMM activation. Using this technique, memory-mapped address space that is normally used for non-SMM purposes is employed for SMM operations in a method that is transparent to the system and application programs. Advantageously, DRAM that may not be normally available for usage due to the presence of other memory-mapped devices residing in the same address space is made available for SMM operations.
摘要翻译：系统管理模式对于正常的系统操作是透明的，并且动态RAM（DRAM）在上部存储器块地址范围中可用，通常在许多配置中不可访问。因此，DRAM有利地用于获得系统管理模式的读/写存储要求。系统管理模式通过在“即时”（JIT）基础上将SMM存储器切换到DRAM上部存储器块空间中，及时地将上部存储器块存储器映射的地址空间与其他非DRAM资源进行时分多路复用。 JIT操作通过在SMM输入之后锁存从CPU发出的第一个存储器地址来实现。第一个存储器地址被指定为向下延伸到存储器地址空间的存储器块的顶部地址，定义了SMM存储器范围。在SMM存储器范围内寻址的所有后续存储器访问都定向到DRAM上部存储器块，而不管通常位于与SMM存储器范围相同的地址范围内的任何其他存储器映射资源。在发生SMM恢复指令时，存储器设备映射被自动恢复到在SMM激活之前存在的配置。使用这种技术，通常用于非SMM目的的内存映射地址空间用于对系统和应用程序透明的方法中的SMM操作。有利的是，由于驻留在相同地址空间中的其他存储器映射设备的存在，可能不能正常使用的DRAM可用于SMM操作。
