Abstract: Systems and switching energy sources are provided for power rail transient compensation. One system includes a voltage regulator having an output coupled to a power rail; a switching energy source configured to provide a determined amount of energy to the power rail responsive to a current transient on the power rail exceeding a determined rate of change; and a timer circuit configured to turn off the switching energy source a determined interval after the switching energy source begins to provide the determined amount of energy to the power rail.

Abstract: In general, techniques are described for processing a set of high-resolution images of an integrated circuit, the images captured at different locations with respect to the integrated circuit, to automatically align and “stitch” the set of high-resolution images into a larger composite image. For example, an imaging system as described herein may use sampled feature points distributed across different grid tiles within overlap regions for pairs of images to match feature points to inform the alignments of a pair with respect to each image in the pair. The system may in some cases further apply a bundle adjustment to iteratively align and refine the alignment results for each image in a set of images being processed. In some examples, the bundle adjustment is a best-fit adjustment based on minimizing the net error associated with the alignment of the set of images.

Abstract: A routing platform for routing 4G and 5G mobile data traffic in a mobile core networks implementing Option-3 of 5G Non-Standalone deployment. The routing platform captures S6a Diameter messages sent between a Mobility Management Entity (MME) and a Home Subscriber Server (HSS) and examines the captured messages to determine whether a user equipment (UE) is configured for a 5G data connection. The routing platform intercepts a GTP Create-Session-Request message sent from a Serving Gateway (SGW) and determines whether the GTP message is associated with the UE previously determined to be configured for a 5G data connection. If the GTP message is associated with the UE configured for a 5G data connection, the GTP message is either sent to a dedicated 5G Packet Network Data Gateway (PGW) or the GTP message is modified so that a single PGW handling both 4G and 5G traffic can establish a 5G session for the UE.

Abstract: This disclosure generally relates to time and timer techniques that may be used to virtualize one or more virtual machines. In an example, it may be possible to save and restore a timer of a virtual machine while preserving timer information associated with the timer (e.g., an expiration time, whether the most recent expiration has been signaled, and the enable bit, etc.). For example, a first mode may enable restoring a timer based on a previously-existing enable bit, thereby retaining the state of the timer (e.g., whether the timer is programmed to fire and/or whether the most recent expiration has been signaled). By contrast, a second mode of setting a timer may automatically set the enable bit, thereby automatically enabling the timer to fire, as may be expected by a virtual machine when setting a timer.

Abstract: An apparatus includes a controller die and a group of dies that communicate with each other via a transmission line. Less than all of the dies of the group includes a respective on-die termination resistance circuit coupled to the transmission line. In some embodiments, one of the dies that includes an on-die termination resistance circuit is an end die of the group. In particular embodiments, the end die is the only die of the group that includes an on-die termination resistance circuit coupled to the transmission line. Transmission frequencies or data rates may be increased without degrading signal quality by removing capacitance associated with on-die termination resistance circuits from at least one of the dies of the group.

Abstract: This disclosure generally relates to hypervisor memory virtualization. Techniques disclosed herein improve peripheral component interconnect express (PCI-e) device interoperability with a virtual machine. As an example, when a direct-memory access request is received from a PCI-e device but the target memory is currently unmapped, an indication may be provided to a memory paging processor so as to page-in the memory, such that the PCI-e device may continue to function normally. In some examples, the access request may be buffered and replayed once the memory is paged-in, or the access request may be retried, among other examples.

Abstract: Speculative side channels exist when memory is accessed by speculatively-executed processor instructions. Embodiments use uncacheable memory mappings to close speculative side channels that could allow an unprivileged execution context to access a privileged execution context's memory. Based on allocation of memory location(s) to the unprivileged execution context, embodiments map these memory location(s) as uncacheable within first page table(s) corresponding to the privileged execution context, but map those same memory locations as cacheable within second page table(s) corresponding to the unprivileged execution context. This prevents a processor from carrying out speculative execution of instruction(s) from the privileged execution context that access any of this memory allocated to the unprivileged execution context, due to the unprivileged execution context's memory being mapped as uncacheable for the privileged execution context.

Abstract: This disclosure generally relates to hypervisor memory virtualization. In an example, multiple page table stages may be used to provide a page table that may be used by a processor when processing a workload for a nested virtual machine. An intermediate (e.g., nested) hypervisor may request an additional page table stage from a parent hypervisor, which may be used to virtualize memory for one or more nested virtual machines managed by the intermediate hypervisor. Accordingly, a processor may use the additional page table stages to ultimately translate a virtual memory address for a nested virtual machine to a physical memory address.

Abstract: A Slicing Agent node is deployed between standard Home Subscriber Server (HSS) node and a Serving General Packet Radio Service Support Node (SGSN) node, a Mobility Management Entity (MME) node, or a 3rd Generation Partnership Project Authentication Authorization and Accounting (3GPP AAA) node on S6a/S6d/SWx interfaces of a Core Network. The Slicing Agent node selects the Packet Data Gateway (PGW) and communicates the identifying information of the selected PGW to SGSN/MME/3GPP AAA nodes. The PGW is selected to serve subscriber sessions based on the subscriber's profile, usage, and business needs. The Slicing Agent node can be positioned in any Core Network setup around the globe irrespective of whether it is a roaming or a non-roaming scenario for subscribers/devices having global or country-specific Subscriber Identity Modules (SIMs), without requiring any enhancements or upgrades in legacy or existing network nodes including SGSN, MME, 3GPP AAA and HSS.
