摘要:
A prefetching control system provided for a processor. The prefetching queue may include an arbiter, a cache queue and a prefetch queue. The arbiter issues requests including read requests. Responsive to a read request, the cache queue issues a control signal. The prefetch queue receives the control signal and an address associated with the read request. When the received address is a member of a pattern of read requests from sequential memory locations, the prefetch queue issues a prefetch request to the arbiter.

The invention relates to a metal/plastic hybrid and to a shaped body produced therefrom. By combining metallic additives in plastic, it has been shown for the first time that specific volume resistances of less than 10−2 Ωcm can be realized while the compounds have, at the same time, a good processability during the injection molding process.

A method and apparatus for current detection for microelectronic devices using source-switched sensors. An embodiment of a current detector for a microelectronic device includes a first voltage sensor and a second voltage sensor. The first voltage sensor is to measure a first voltage of the microelectronic device during a first time period and a second voltage of the microelectronic device during a second time period. The second voltage sensor is to measure the second voltage during the first time period and the first voltage during the second time period. A voltage value is equal to the sum of the first voltage measured by the first sensor plus the first voltage measured by the second sensor, minus the sum of the second voltage measured by the first sensor plus the second voltage measured by the second sensor. Other embodiments are also described and claimed.
摘要:
In one embodiment of the present invention, a method includes verifying an initiating logical processor of a system; validating a trusted agent with the initiating logical processor if the initiating logical processor is verified; and launching the trusted agent on a plurality of processors of the system if the trusted agent is validated. After execution of such a trusted agent, a secure kernel may then be launched, in certain embodiments. The system may be a multiprocessor server system having a partially or fully connected topology with arbitrary point-to-point interconnects, for example.

A method and an apparatus to sense supply voltage have been disclosed. In one embodiment, the apparatus includes a resistor having a first end and a second end, the first end coupled to a voltage supply and a ring oscillator sensor coupled between the second end of the resistor and ground, the ring oscillator sensor having an output coupled to a computational element. Other embodiments have been claimed and described.
摘要:
Methods and apparatuses provide voltage regulation for a processor. Control or configuration parameters for a voltage regulator (VR) are provided digitally over a configuration bus to a VR controller. The parameters may be provided directly from a storage element, or via a processing element or processor core. Based in whole or in part on the parameters, the VR controller provides an output control signal to affect a power output from a power converter to the processing element. In one embodiment, the VR controller is integrated onto the same IC as the processing element.

A technique to modify a timer. More particularly, at least one embodiment of the invention relates to a technique to modify a timer value without the timer advancing by a significant amount.
摘要:
A system is disclosed. The system includes a central processing unit (CPU) to operate in one or more low power sleep states, and a power converter. The power converter includes phase inductors; and one or more power switches to drive the phase inductors. The one or more power switches are deactivated during the CPU sleep state.
摘要:
In one embodiment, the present invention includes a method for performing an operation in a processor of a uniprocessor system, initiating a write transaction to send a result of the operation to a memory of the uniprocessor system, and issuing a global observation point for the write transaction to the processor before the result is written into the memory. In some embodiments, the global observation point may be issued earlier than if the processor were in a multiprocessor system. Other embodiments are described and claimed.
