Abstract: Failure and repair information collected during self-testing of arrays in an integrated circuit is stored in a centralized array in the integrated circuit. In that way, a centralized array can be read out to provide failure and repair information on the arrays in the integrated circuit rather than having to read from each array. In addition, the failure and repair information may also be stored in the array under test for certain of the arrays.

Abstract: A method and microprocessor are described for efficiently executing load instructions out-of-order (speculatively). The microprocessor includes an enhanced load store unit (LSU) and an enhanced instruction decoder. The enhanced LSU receives a plurality of out-of-order value addresses, and sends a resync signal to the enhanced instruction decoder when an execution error associated with a particular load instruction occurs. The enhanced instruction decoder stores a specific address associated with the particular load instruction, and increments a counter value that indicates how many times the resync signal was sent by the resync predictor. When the counter value reaches a predetermined threshold, subsequent load instructions from the specific address are executed in order (non-speculatively).

Abstract: Scalability of a strain-inducing mechanism on the basis of a stressed dielectric overlayer may be enhanced by forming a single stress-inducing layer in combination with contact trenches, which may shield a significant amount of a non-desired stress component in the complementary transistor, while also providing a strain component in the transistor width direction when the contact material may be provided with a desired internal stress level.

Abstract: A graphics processor or a graphics block for use in a processor includes a type buffer used for determining if a currently processed pixel requires further processing. Each pixel has a number of sub-pixels and each sub-pixel line includes at least one counter that is stored in an edge buffer. A limited edge buffer that can store edge buffer values in a limited range can be employed. Each buffer can include information regarding the whole screen or a portion of thereof. The edge buffer also can be an external or internal buffer, and when implemented internally, the graphics processor or graphics block need not employ a bi-directional bus.

Abstract: Techniques are disclosed relating to resource contention resolution in a pre-memory environment. Prior to system memory being accessible, a resource control processing element controls access to a hardware resource by a plurality of processing elements by granting received requests from the processing elements for access to the resource. The resource control processing element may prioritize requests based on a determined amount of utilization of the hardware resource by individual ones of the processing elements. In one embodiment, processing elements request for information from a bus controller (e.g., an SMBus controller) that is usable to initialize system memory. The resource control processing element may respond to the requests by retrieving the requested information from the controller and providing that information to the processing element or by retrieving the requested information from a cache and providing that information to the processing element.

Abstract: Electronic component protection power supply clamp circuits comprising a plurality of p-type channel metal-oxide-semiconductor (PMOS) and n-type channel metal-oxide-semiconductor (NMOS) transistors are described. These clamp circuits use a feedback latching circuit to retain an electrostatic discharge (ESD)-triggered state and efficiently conduct ESD current that has been diverted into the power supply, in order to dissipate ESD energy. The feedback latching circuit also maintains a clamp transistor in its off state if the clamp circuit powers up untriggered, thus enhancing the clamp circuit's immunity to noise during normal operation. Passive resistance initialization of key nodes to an untriggered state, as well as passive resistance gate input loading of a large ESD clamping transistor, further enhances the clamp circuit's immunity to false triggering.

Abstract: An input/output memory management unit (IOMMU) configured to control requests by an I/O device to a system memory includes control logic that may perform a two-level guest translation to translate an address associated with an I/O device-generated request using translation data stored in the system memory. The translation data includes a device table having a number of entries. The control logic may select the device table entry for a given request by the using a device identifier that corresponds to the I/O device that generates the request. The translation data may also include a first set of I/O page tables including a set of guest page tables and a set of nested page tables. The selected device table entry for the given request may include a pointer to the set of guest translation tables, and a last guest translation table includes a pointer to the set of nested page tables.

Abstract: A processing system has one or more processors that implement a plurality of virtual machines that are managed by a hypervisor. Each virtual machine provides a secure and isolated hardware-emulation environment for execution of one or more corresponding guest operating systems (OSs). Each guest OS, as well as the hypervisor itself, has an associated address space, identified with a corresponding “WorldID.” Further, each virtual machine and the hypervisor can manage multiple lower-level address spaces, identified with a corresponding “address space identifier” or “ASID”. The address translation logic of the processing system translates the WorldID and ASID of the current address space context of the processing system to corresponding WorldID and ASID search keys, which have fewer bits than the original identifiers and thus require less complex translation lookaside buffer (TLB) hit logic.

In one aspect, respective openings for the substrate diode may be formed after the formation of a corresponding sidewall spacer structure used for defining the drain and source regions, thereby obtaining a significant lateral distribution of the dopants in the diode areas, which may therefore provide sufficient process margins during a subsequent silicidation sequence on the basis of a removal of the spacers in the transistor devices. In a further aspect, in addition to or alternatively, an offset spacer may be formed substantially without affecting the configuration of respective transistor devices.

Thus, the first latch may be powered down while the second latch remains powered on.

Abstract: Presented are systems and methods that change the order in which triangles are rendered, to improve post-transform vertex cache efficiency and reduce view-independent overdraw. The resulting triangle orders are orders magnitude faster to compute compared to previous methods. The improvements in processing speed allow such methods to be performed on a model after it is loaded (i.e., when more information on the host hardware is available). Also, such methods can be executed interactively, allowing for re-optimization in case of changes to geometry or topology, which happen often in CAD/CAM applications.

Embodiments are usable with known bus protocols.

The signal generator includes a plurality of stacked oscillators arranged between two reference voltages, such that each oscillator in the stack generates an oscillating signal having a different peak voltage. Each oscillator stage in a designated oscillator includes a transistor that is connected to a transistor of a corresponding stage in another oscillator. This arrangement of the oscillators provides for charge transfer between the corresponding stages to provide for similar voltage swings in each oscillating signal, as well as to provide for predictable phase relationship between the oscillating signals.
