Appl. No.:

10/424530

International Classification:

G06F015/00
G06F007/38

US Classification:

712/245000

Abstract:

The selection between instruction threads in a SMT processor for the purpose of interleaving instructions from the different instruction threads may be modified to accommodate certain processor events or conditions. During each processor clock cycle, an interleave rule enforcement component produces at least one base instruction thread selection signal that indicates a particular one of the instruction threads for passing an instruction from that particular thread into a stream of interleaved instructions. Thread selection modification is provided by an interleave modification component that generates a final thread selection signal based upon the base thread selection signal and a feedback signal derived from one or more conditions or events in the various processor elements. This final thread selection signal may indicate the same instruction thread indicated by the base thread selection signal or a different one of the instruction threads for passing an instruction into the interleaved stream of instructions.

International Classification:

US Classification:

712/245000

Abstract:

A processor interleaves instructions according to a priority rule which determines the frequency with which instructions from each respective thread are selected and added to an interleaved stream of instructions to be processed in the data processor. The frequency with which each thread is selected according to the rule may be based on the priorities assigned to the instruction threads. A randomization is inserted into the interleaving process so that the selection of an instruction thread during any particular clock cycle is not based solely by the priority rule, but is also based in part on a random or pseudo random element. This randomization is inserted into the instruction thread selection process so as to vary the order in which instructions are selected from the various instruction threads while preserving the overall frequency of thread selection (i.e. how often threads are selected) set by the priority rule.

International Classification:

G06F001/26

US Classification:

713/300000

Abstract:

A register in the control unit of the CPU that is used to keep track of the address of the current or next instruction is called a program counter. In an SMT system having two threads, the CPU has program counters for both threads and means for alternately selecting between program counters to determine which thread supplies an instruction to the instruction fetch unit (IFU). The software for the SMT assigns a priority to threads entering the code stream. Instructions from the threads are read from the instruction queues pseudo-randomly and proportional to their execution priorities in the normal power mode. If both threads have a lowest priority, a low power mode is set generating a gated select time every N clock cycles of a clock when valid instructions are loaded. N may be adjusted to vary the amount of power savings and the gated select time.

International Classification:

G06F009/46

US Classification:

718/100000

Abstract:

Each instruction thread in a SMT processor is associated with a software assigned base input processing priority. Unless some predefined event or circumstance occurs with an instruction being processed or to be processed, the base input processing priorities of the respective threads are used to determine the interleave frequency between the threads according to some instruction interleave rule. However, upon the occurrence of some predefined event or circumstance in the processor related to a particular instruction thread, the base input processing priority of one or more instruction threads is adjusted to produce one more adjusted priority values. The instruction interleave rule is then enforced according to the adjusted priority value or values together with any base input processing priority values that have not been subject to adjustment.

International Classification:

H04W 88/02

US Classification:

455572

Abstract:

Personal digital assistant devices are provided that query power subsystems to determine a level of battery power currently available for operating processes, and further determine a number of screen display changes that may be effected on a persistent display device at that determined level. If the determined number of screen display changes that may be effected at the determined level of available battery power fails to meet a specified minimum threshold number of images, the processing unit powers down subsystems of the personal digital assistant device and causes a highest listed image of a prioritized list of screen image instances to be displayed on the persistent display device, which persistently displays the image after a loss of power.

G06F 3/01

Abstract:

A method, apparatus, system, and computer program product for identifying a recommendation for an activity. Biometric data for a set of biometric parameters is received for a user. A set of comparable users having saved biometric data for the set of biometric parameters that are comparable to the biometric data for the set of biometric parameters for a user is identified. The recommendation for the activity is determined based on prior recommendations from the set of comparable users for the activity. The recommendation for the activity is sent to a client device, wherein the client device displays the recommendation for the activity to the user.
