Abstract: Aspects relate to Input/Output (IO) Memory Management Units (MMUs) that include hardware structures for implementing virtualization. Some implementations allow guests to setup and maintain device IO tables within memory regions to which those guests have been given permissions by a hypervisor. Some implementations provide hardware page table walking capability within the IOMMU, while other implementations provide static tables. Such static tables may be maintained by a hypervisor on behalf of guests. Some implementations reduce a frequency of interrupts or invocation of hypervisor by allowing transactions to be setup by guests without hypervisor involvement within their assigned device IO regions. Devices may communicate with IOMMU to setup the requested memory transaction, and completion thereof may be signaled to the guest without hypervisor involvement. Various other aspects will be evident from the disclosure.

Abstract: Certain aspects of the present disclosure provide techniques for processing computing resource access requests from users of an application service. An example method generally includes measuring computing resource access metrics over a time window for a user of a computing system. The measured computing access metrics for the user of the computing system are determined to exceed a threshold. Based on determining that the measured computing access metrics for the user of the computing system exceeds the threshold, computing resource access requests from the user of the computing system are migrated from a first queue to a second queue, wherein the first queue comprises a rate-unlimited queue and the second queue comprises a rate-controlled queue having a defined rate for processing received requests. Computing resource access requests from the user of the computing system are processed based on the defined rate for processing received requests.

Abstract: Techniques for neural network processing using specialized data representation are disclosed. Input data for manipulation in a layer of a neural network is obtained. The input data includes image data, where the image data is represented in bfloat16 format without loss of precision. The manipulation of the input data is performed on a processor that supports single-precision operations. The input data is converted to a 16-bit reduced floating-point representation, where the reduced floating-point representation comprises an alternative single-precision data representation mode. The input data is manipulated with one or more 16-bit reduced floating-point data elements. The manipulation includes a multiply and add-accumulate operation. The manipulation further includes a unary operation, a binary operation, or a conversion operation. A result of the manipulating is forwarded to a next layer of the neural network.

Abstract: Techniques are disclosed for address manipulation using indices and tags. A first index is generated from bits of a processor program counter, where the first index is used to access a branch predictor bimodal table. A first branch prediction is provided from the bimodal table, based on the first index. The first branch prediction is matched against N tables, where the tables contain prior branch histories, and where: the branch history in table T(N) is of greater length than the branch history of table T(N-1), and the branch history in table T(N-1) is of greater length than the branch history of table T(N-2). A processor address is manipulated using a greatest length of hits of branch prediction matches from the N tables, based on one or more hits occurring. The branch predictor address is manipulated using the first branch prediction from the bimodal table, based on zero hits occurring.

The rear-facing camera may be directed at a front of a trailer that is coupled to the vehicle at a hitchball. An approximate lateral location of the hitchball coupled to the vehicle may be determined by obtaining a plurality of cropped images along a hitch drawbar coupled to the vehicle by stepping along the vertical direction, and performing a stepwise lateral scan, centered at the hitch drawbar.

Abstract: Embodiments of the invention provide compositions including bio degradable polymers, medical implants fabricated from these compositions and methods of using such implants. Many embodiments provide medical implants comprising a first polymer backbone having a first rate of biodegradation and a second polymer backbone having a second rate of biodegradation faster than the first rate. In some embodiments, the second backbone is configured to be replaced by a natural tissue layer. The first backbone provides a scaffold for the implant while the second backbone degrades. This scaffold can enhance mechanical properties of the implant including various aspects of mechanical strength such as tensile, bending, hoop and yield strength; and elasticity. The scaffold also serves to maintain a minimum level of structural support of the implant during the period of degradation of the second backbone or for the entire life of the implant so that the implant does not mechanically fail.

Abstract: A system and method are described herein for estimating power usage of various components of a CPU and controlling voltage regulators based on the estimated power usage. The power estimates may be based on digital power meter readings at each component, on voltage information from a voltage regulator, and on other power information. This power information is transmitted over a mesh interconnect disposed throughout the CPU such that power estimation can be accurately calculated and used to control voltage regulators without being limited by external bus speeds. More of the power management processes and components may be disposed on the CPU and connected to the mesh interconnect. These power management processes include various calibrations, adjustments, and limits so as efficiently manage and use the more rapidly processed power estimations.
