  • Patent number: 10678691
    Abstract: Systems, apparatuses, and methods for implementing coherence flows for dual-processing coherence and memory cache pipelines are disclosed. A dual-processing pipeline includes a coherence processing pipeline and a memory cache processing pipeline. When a transaction is issued to the dual-processing pipeline, the coherence processing pipeline performs a duplicate tag lookup in parallel with the memory cache processing pipeline performing a memory cache tag lookup for the transaction. If the duplicate tag lookup is a hit, then the coherence processing pipeline locks the matching entry, the memory cache processing pipeline discards the original transaction, and a copyback request is sent to a coherent agent identified by the matching entry. When the copyback response is received by a communication fabric, the copyback response is issued to the memory cache processing pipeline. When the copyback response passes the global ordering point, the coherence processing pipeline clears the lock on the matching entry.

  • Publication number: 20200081837
    Abstract: Systems, apparatuses, and methods for implementing a distributed global ordering point are disclosed. A system includes at least a communication fabric, sequencing logic, and a plurality of coherence point pipelines. Each coherence point pipeline receives transactions from the communication fabric and then performs coherence operations and a memory cache lookup for the received transactions. The global ordering point of the system is distributed across the outputs of the separate coherence point pipelines. Device-ordered transactions travelling upstream toward memory are assigned sequence numbers by the sequencing logic. The transactions are speculatively issued from the communication fabric to the coherence point pipelines. Speculatively issuing the transactions to the coherence point pipelines may cause the transactions to pass through the distributed global ordering point out of order. Control logic on the downstream path reorders the transactions based on the assigned sequence numbers.

  • Publication number: 20200081836
    Abstract: Systems, apparatuses, and methods for reducing memory cache control command hops through a fabric are disclosed. A system includes an interconnect fabric, a plurality of transaction processing queues, and a plurality of memory pipelines. Each memory pipeline includes an arbiter, a combined coherence point and memory cache controller unit, and a memory controller coupled to a memory channel. Each combined unit includes a memory cache controller, a memory cache, and a duplicate tag structure. A single arbiter per memory pipeline performs arbitration across the transaction processing queues to select a transaction address to feed the memory pipeline's combined unit. The combined unit performs coherence operations and a memory cache lookup for the selected transaction. Only after processing is completed in the combined unit is the transaction moved out of its transaction processing queue, reducing power consumption caused by data movement through the fabric.

  • Patent number: 10511606
    Abstract: It can be difficult to manage assets, particularly when determining ownership of assets. Systems and methods for facilitating identification of ownership of an asset include identifying an asset (e.g., an item capable of being owned), identifying one or more actors (e.g., an entity capable of owning an asset), and identifying interactions between the asset and each actor. The systems and methods additionally apply a decay factor to the identified interactions to cause a reduction in the significance of the identified interactions between the asset and each actor and produce an asset ownership score for each actor based on the decay-modified interactions. The resulting asset ownership score for each actor is provided to an entity in a fashion that allows the entity to identify a comparative likelihood that each actor is a potential owner of the asset.

The acoustic wave focused section is formed by an acoustic wave focused cavity filled with acoustic material. The acoustic wave focused section controls the acoustic wave propagation path through the change of a section of the cavity and the change of material equivalent parameters in the cavity, so that the acoustic waves are focused and propagate along the curve. The acoustic wave absorption section realizes efficient broadband sound absorption through the filled sound absorption materials and the arranged periodic local oscillators along an ultralong path of acoustic wave absorption labyrinth passage.

  • Patent number: 10417146
    Abstract: An embodiment of an apparatus includes a retry queue circuit, a transaction arbiter circuit, and a plurality of transaction buffers. The retry queue circuit may store one or more entries corresponding to one or more memory transactions. A position in the retry queue circuit of an entry of the one or more entries may correspond to a priority for processing a memory transaction corresponding to the entry. The transaction arbiter circuit may receive a real-time memory transaction from a particular transaction buffer. In response to a determination that the real-time memory transaction is unable to be processed, the transaction arbiter circuit may create an entry for the real-time memory transaction in the retry queue circuit. In response to a determination that a bulk memory transaction is scheduled for processing prior to the real-time memory transaction, the transaction arbiter circuit may upgrade the bulk memory transaction to use real-time memory resources.
