20080208512 | Maximal Temperature Logging - A computer implemented method, data processing system, and processor are provided for logging a maximal temperature in an integrated circuit. A digital thermal sensor senses a temperature in the integrated circuit. The sensed temperature of the digital thermal sensor is read and a determination is made as to whether the sensed temperature is higher than a current maximal temperature. The sensed temperature is logged in response to the sensed temperature being higher than the current maximal temperature. The sensed temperature becomes a new maximal temperature for the integrated circuit. | 08-28-2008 |

20080272820 | Circuit to Reduce Transient Current Swings During Mode Transitions of High Frequency/High Power Chips - A method, an apparatus, and a computer program are provided to reduce transient current swings during mode transitions. Traditionally, transient supply voltage fluctuations on a chip account for a large portion of the power supply. The number of series inductances and resistances are typically minimized, while adding large decoupling capacitances between the supply voltage and ground. However, situations may arise where reduction of series inductances and resistances cannot be accomplished. Therefore, to assist in controlling the transient current swings, reduction of clocking frequencies are performed in a controlled manner. | 11-06-2008 |
20090030644 | Tracing Thermal Data Via Performance Monitoring - A computer implemented method, data processing system, and processor are provided for tracing thermal data via performance monitoring. A performance monitor is set into a tracing mode. Temperatures are sensed by a digital thermal sensor over a time period. The sensed temperatures are stored in a data structure and a trace of the sensed temperatures is graphically displayed. | 01-29-2009 |
20090048720 | Support of Deep Power Savings Mode and Partial Good in a Thermal Management System - A computer implemented method, data processing system, and processor are provided for managing a thermal management system. A determination is made as to whether a plurality of digital thermal sensors is faulty or functional. A power savings mode of at least one unit within the integrated circuit associated with the functional digital thermal sensor is monitored in response to at least one of the plurality of digital thermal sensors being functional. A functional digital thermal sensor is disabled in response to the at least one unit being in a power savings mode. | 02-19-2009 |
20090099806 | Thermal Interrupt Generation - A computer implemented method, data processing system, and processor are provided for thermal interrupt generation. An interrupt temperature is set to a first temperature and an interrupt direction is to a greater than or equal to determination. A determination is made as to whether a sensed temperature from a digital thermal sensor meets or exceeds the interrupt temperature in response to the interrupt direction. A first interrupt is generated in response to the sensed temperature meeting or exceeding the interrupt temperature. | 04-16-2009 |
20090119552 | Dynamic Frequency Scaling Sequence for Multi-Gigahertz Microprocessors - The present invention provides for reducing current spikes in a circuit when changing clocking frequencies. A first frequency is applied to a clock distribution network. A final frequency is selected. The first frequency is applied to a logic element over the clock distribution network. A hold signal is applied to the logic element. The clock rate of the clock distribution network is changed from the first frequency to the final frequency. The hold signal is unapplied to the logic element. | 05-07-2009 |
