Abstract: An agent may be configured to invoke a first eviction operation that is interruptible by probe operations when receiving a first type of eviction message and invoke a second eviction operation in which probe operations are interruptible by the second eviction operation when receiving a second type of eviction message. In some implementations, the agent may maintain a data storage that is inclusive of at least one of unique or dirty cache blocks in a cache maintained by an agent that transmits the second type of eviction message. In some implementations, the agent may prevent a cache block from transitioning from a modified state to an exclusive state when the agent invokes the second eviction operation to evict the cache block. In some implementations, the agent may convert from the second eviction operation to the first eviction operation when receiving the second type of eviction message.

Abstract: Prefetch circuitry may be configured to transmit a message to prefetch one or more cache blocks of a group. The message may indicate an address for the group of cache blocks and a bit field that indicates the one or more cache blocks of the group to prefetch. In some implementations, the message may target a higher level cache to prefetch the one or more cache blocks, and the message may be transmitted to the higher level cache via a lower level cache. In some implementations, the message may target a higher level cache to prefetch the one or more cache blocks, the message may be transmitted to a lower level cache via a first command bus, and the lower level cache may forward the message to the higher level cache via a second command bus.

Abstract: Prefetch circuitry may be configured to transmit a message to cancel a prefetch of one or more cache blocks of a group. The message may correspond to a prefetch message by indicating an address for the group and a bit field for the one or more cache blocks of the group to cancel. In some implementations, the message may target a higher level cache to cancel prefetching the one or more cache blocks, and the message may be transmitted to the higher level cache via a lower level cache. In some implementations, the message may target a higher level cache to cancel prefetching the one or more cache blocks, the message may be transmitted to a lower level cache via a first command bus, and the lower level cache may forward the message to the higher level cache via a second command bus.

Abstract: A method and apparatus for a speculative request indicator is described. A method includes providing, for a cache hierarchy, a messaging protocol used for transfer operations among agents in the cache hierarchy, the messaging protocol indicating acceptable cache coherency states for a cache block indicated in a request message and providing, in the messaging protocol for selection by an agent, a speculative request indicator when sending the request message, wherein the speculative request indicator differentiates between a demand request and a speculative request with respect to the cache block.

Abstract: A method and apparatus for a cache coherency state request vector is described. A method includes selecting, by a first agent, one or more bits in a cache coherency state request vector, where a selected bit in the cache coherency state request vector indicates an acceptable cache coherency state for a cache block indicated in a request message, transmitting, by the first agent to a second agent, the request message for the cache block, the request message including the cache coherency state request vector, and receiving, by the first agent from the second agent, a response message with a cache coherency response state, wherein the cache coherency response state indicates a cache coherency state responsive to the cache coherency state request vector.

Abstract: First agent circuitry may receive from a second agent a first request and a first set of one or more bits. The first request may be part of a data operation. The first agent circuitry may transmit to the second agent a message including a first response to the first request, the first set of one or more bits, a second request, and a second set of one or more bits. The second set of one or more bits may be generated by the first agent circuitry to transmit state information about the second request. In some implementations, a set of one or more wires may be generated for transmission of the second set of one or more bits. The first agent circuitry may receive from the second agent a second response to the second request and the second set of one or more bits.

Abstract: A data responder may determine a selection between granting a request for a priority byte to be prioritized for transmission ahead of other bytes via a bus and ignoring the request. Granting the request may include transferring a block of bytes of data across multiple clock cycles with the priority byte transferred in a first clock cycle before other clock cycles of the multiple clock cycles. Ignoring the request may include transferring the block across multiple clock cycles with the priority byte transferred in a clock cycle after the first clock cycle. The data responder may receive the request from a data requestor. The data responder may assert a signal on a wire, connected to the data requestor, to indicate a grant of the request and a transfer of the priority byte in the first clock cycle.

Abstract: A method for managing orders of operations between one or more clients and one or more servers is disclosed. The method includes partitioning addressable regions of logical servers on or within an interconnect link into multiple regions including a first orderable region, and providing logical client an ability to push ordering responsibility within the first orderable region to a server. Over the first orderable region, two request messages for access to memory-mapped sources including two respective operations are transmitted, and the two request messages originate from a same logical client. The ordering responsibility can include a first rule for order of operations between the two request messages.

Abstract: An injectable hydrogel network is provided distinguishing a non-covalently cross-linked hydrogel network with polymers functionalized with hydrophobic fatty pendant groups hydrophobically cross-linked with liposomal nanoparticles in which the liposomal nanoparticles are the cross-linkers. As the hydrogel is injectable, it is easily administered under the skin and does not require invasive surgical implantation. After injection the hydrogel rapidly self-heals to form a robust solid-like depot that can persist in the body over relevant timescales. The material does not cause a negative immune response like many other materials do. The hydrogel can gradually degrade over time in the body and therefore would not require surgical removal.

Abstract: Systems and methods are disclosed for variable depth pipelines for error correction. For example, some methods may include changing the depth of a pipeline in response to an error signal from a stage of the pipeline. Changing the depth of the pipeline may include routing signals from the stage of the pipeline that resulted in the error signal through an error correction stage of the pipeline to a next stage of the pipeline that previously received output signals from the stage of the pipeline that resulted in the error signal. The methods may include continuing to route signals through the error correction stage of the pipeline to the next stage of the pipeline for multiple clock cycles until a pipeline bubble event is detected.

Abstract: Ferroelectric diodes comprising materials such as aluminum scandium nitride (AlScN) or hafnium zirconium oxide (HfZrO2) may be formed atop semiconductor structures such as CMOS wafers to create storage memory cells. search Ternary Content Addressable Memory (TCAM) cells, and/neural circuitry. The diodes are non-volatile and field programmable via pulsing to a pulse-number-dependent analog state, with high on/off and self-rectifying ratios. Cells may be formed, for example, with two diodes that are oppositely polarized, and may be achieved without transistors to form, for example, 0T-2R structures.

Abstract: In virtual reality (VR) and augmented reality (AR), eye tracking may be performed to determine the user's gaze direction. The gaze direction may be used to enhance user interaction. However, when a user gazes in a particular direction, it could sometimes be the case that there are multiple items located in that gaze direction, each at a different depth. The gaze of direction alone might not be indicative of the item at which the user is looking. Therefore, in some embodiments, to try to further enhance user interaction, a gaze depth of the gaze may be determined. Some embodiments are directed to performing eye tracking to detect a gaze depth of a human's gaze and modifying a user interface (UI) responsive to a change in the gaze depth.
