Abstract: A processing system includes a plurality of compute units, with each compute unit having an associated first cache of a plurality of first caches, and a second cache shared by the plurality of compute units. The second cache operates to manage transfers of caches between the first caches of the plurality of first caches such that when multiple candidate first caches contain a valid copy of a requested cacheline, the second cache selects the candidate first cache having the shortest total path from the second cache to the candidate first cache and from the candidate first cache to the compute unit issuing a request for the requested cacheline.

Abstract: A processor includes a cache having two or more test regions and a larger non-test region. The processor further includes a cache controller that applies different cache replacement policies to the different test regions of the cache, and a performance monitor that measures performance metrics for the different test regions, such as a cache hit rate at each test region. Based on the performance metrics, the cache controller selects a cache replacement policy for the non-test region, such as selecting the replacement policy associated with the test region having the better performance metrics among the different test regions. The processor deskews the memory access measurements in response to a difference in the amount of accesses to the different test regions exceeding a threshold.

Abstract: Techniques for performing cache operations are provided. The techniques include tracking performance events for a plurality of test sets of a cache, detecting a replacement policy change trigger event associated with a test set of the plurality of test sets, and in response to the replacement policy change trigger event, operating non-test sets of the cache according to a replacement policy associated with the test set.

Abstract: Systems and techniques for dynamic selection of policy that determines whether copies of shared cache lines in a processor core complex are to be stored and maintained in a level 3 (L3) cache of the processor core complex are based on one or more cache line sharing parameters or based on a counter that tracks L3 cache misses and cache-to-cache (C2C) transfers in the processor core complex, according to various embodiments. Shared cache lines are shared between processor cores or between threads. By comparing either the cache line sharing parameters or the counter to corresponding thresholds, a policy is set which defines whether copies of shared cache lines at such indices are to be retained in the L3 cache.

Abstract: Techniques are described for securely updating a point-of-sale (POS) system that includes a merchant-facing device and a buyer-facing device. For instance, the merchant-facing device may execute first software that provides first POS functionality and the buyer-facing device may execute second software that provides second POS functionality. To update both devices, the merchant-facing device may receive a software update from a payment service via a network connection, and update the first software using the software update. The merchant-facing device can then cause, via a physical connection, the buyer-facing device to reboot in an update mode and send the software update to the buyer-facing device. In response, the buyer-facing device can update the second software using the software update and then reboot in a payments mode. In some instances, the buyer-facing device can then update a secure enclave on the buyer-facing device using the software update.

Abstract: A method includes monitoring one or more metrics for each of a plurality of cache users sharing a cache, and assigning each of the plurality of cache users to one of a plurality of groups based on the monitored one or more metrics.

Abstract: A method of vending an assembled food item. Receiving a request for an assembled food item. Conveying a first food item to a heating element for heating the first food item. Conveying a second food item to a second heating element for heating the second food item. Heating the first food item and second to a predetermined temperature or for an amount of time. After heating the first food item, dispensing the first food item into a first side of a foldable box that is open and dispensing the second food item into a second side of the foldable box. Folding the first side of the foldable box to be positioned substantially above the second side of the foldable box such that the foldable box is in a substantially closed position and such that the first food item is positioned substantially on top of the second food item.

Abstract: A communication network includes: a plurality of nodes in a topology, with each node having an upstream and a downstream neighboring node in the topology; a separate unidirectional communication link coupled between each node and that node's downstream neighboring node; and a separate unidirectional control link coupled between each node and that node's upstream neighboring node. A controller in each node keeps a count of packets sent by that node via the corresponding unidirectional communication link. The controller uses the count of packets sent to determine whether a given packet is allowed to be sent from that node to the downstream neighboring node and, if so, whether a full rate or a throttled rate is to be used for sending the given packet. Based at least in part on the determining, the controller selectively sends the given packet to the downstream neighboring node.

Abstract: An electronic device includes a cache with a cache controller and a cache memory. The electronic device also includes a cache policy manager. The cache policy manager causes the cache controller to use two or more cache policies for cache operations in each of multiple test regions in the cache memory, with different configuration values for the two or more cache policies being used in each test region. The cache policy manager selects a selected configuration value for at least one cache policy of the two or more cache policies based on performance metrics for cache operations while using the different configuration values for the two or more cache policies in the test regions. The cache policy manager causes the cache controller to use the selected configuration value when using the at least one cache policy for cache operations in a main region of the cache memory.
