摘要： An integrated circuit having a temperature sensitive circuit (TSC) to generate a signal indicative of the substrate temperature near the TSC. The integrated circuit has circuitry configured to receive a TSC signal from at least one TSC and to convert the TSC signal to a signal indicative of the integrated circuit's temperature. The thermal control circuit compares the integrated circuit temperature to a threshold and produces a corrective action signal when the temperature exceeds the threshold. The corrective action signal is provided to corrective action circuitry preferably configured to modify the operation of the IC to reduce the IC temperature in proximity to the corresponding TSC.

摘要： A mechanism for controlling instruction fetch and dispatch thread priority settings in a thread switch control register for reducing the occurrence of balance flushes and dispatch flushes for increased power performance of a simultaneous multi-threading data processing system. To achieve a target power efficiency mode of a processor, the illustrative embodiments receive an instruction or command from a higher-level system control to set a current power consumption of the processor. The illustrative embodiments determine a target power efficiency mode for the processor. Once the target power mode is determined, the illustrative embodiments update thread priority settings in a thread switch control register for an executing thread to control balance flush speculation and dispatch flush speculation to achieve the target power efficiency mode.

摘要： Exemplary embodiments provide a computer-implemented method and a system for a startup cycle for a cycle deterministic start. An initializing mechanism applies power to a microprocessor. The initializing mechanism initializes the configuration of the microprocessor. The initializing mechanism initializes a timer. The initializing mechanism then sends a clock start command to the microprocessor. The clocks on the microprocessor are started. Upon the clocks starting, the timer begins and allows temporary transients, such as voltage droop due to a large instantaneous change in demand for current due to the commencement of clock switching. Responsive to the timer reaching a target value, an interrupt unit sends a system reset interrupt. Responsive to the interrupt unit sending the system reset interrupt, an instruction fetch unit fetches a first instruction. This operation will be deterministic to the state of the rest of the microprocessor memory elements (latches, arrays, et al.).

摘要： A processor supporting thread-execution-state-sensitive supervisory commands provides a mechanism for executing supervisory commands for live threads. The commands may be sent from a service processor or another primary processor in the system or may be supplied by the processor itself through supervisory software control. Since the state of execution of one or more threads may change dynamically within a processor core, an external processor will not know the thread execution state at the time the command operates. The method and apparatus provide a command set and logic that supports selective execution of particular commands directed at “alive” threads (or threads in some other determinable execution state), whereby the command is performed only on resources and/or execution units depending on the actual state of thread execution when the command operates within the processor.

摘要： An apparatus for performing imprecise bus tracing in a distributed memory symmetric multiprocessor system is disclosed. The apparatus includes a bus trace macro (BTM) module that can control the snoop traffic seen by one or more of the memory controllers in the data processing system and utilize a local memory attached to the memory controller for storing trace records. After the BTM module is enabled for tracing operations, the BTM module snoops transactions on the interconnect and packs information contained within these transactions into a block of data of a size that matches the write buffers within the memory controller. In addition, the BTM module also includes a dropped record counter for counting the number of address transactions that were not converted to trace records because all the write buffers were completely full. After an occurence of the write buffers full condition, a time stamp trace record is inserted before a new trace record can be written. The time stamp trace record includes a count of the number of address transactions that were not converted to trace records.

摘要： Sensors on the integrated circuit are used to detect the current operating state of the chip, such as frequency, voltage, temperature characteristics, or variation in the integrated circuit manufacturing process. In response, the integrated circuit may choose to modify operational parameters (such as frequency, voltage, or power-down states) in order to dynamically and autonomously maintain an optimal performance and/or power-efficiency operational point.
