摘要:
The present invention extends to methods, systems, and computer program products for providing domain, hull, and geometry shaders in a para-virtualized environment. As such, a guest application executing in a child partition is enabled use a programmable GPU pipeline of a physical GPU. A vGPU (executing in the child partition) is presented to the guest application. The vGPU exposes DDIs of a rendering framework. The DDIs enable the guest application to send graphics commands to the vGPU, including commands for utilizing a domain shader, a hull shader, and/or a geometric shader at a physical GPU. A render component (executing within the root partition) receives physical GPU-specific commands from the vGPU, including commands for using the domain shader, the hull shader, and/or the geometric shader. The render component schedules the physical GPU-specific command(s) for execution at the physical GPU.

The present invention extends to methods, systems, and computer program products for para-virtualized GPGPU computation and GDI acceleration. Some embodiments provide a compute shader to a guest application within a para-virtualized environment. A vGPU in a child partition presents compute shader DDIs for performing GPGPU computations to a guest application. A render component in a root partition receives compute shader commands from the vGPU and schedules the commands for execution at the physical GPU. Other embodiments provide GPU-accelerated GDI rendering capabilities to a guest application within a para-virtualized environment. A vGPU in a child partition provides an API for receiving GDI commands, and sends GDI commands and data to a render component in a root partition. The render component schedules the GDI commands on a 3D rendering device. The 3D rendering device executes the GDI commands at the physical GPU using a sharable GDI surface.

摘要:
Methods and systems are disclosed for virtualizing a graphics accelerator such as a GPU. In one embodiment, a GPU can be paravirtualized. Rather than modeling a complete hardware GPU, paravirtualization may provide for an abstracted software-only GPU that presents a software interface different from that of the underlying hardware. By providing a paravirtualized GPU, a virtual machine may enable a rich user experience with, for example, accelerated 3D rendering and multimedia, without the need for the virtual machine to be associated with a particular GPU product.
摘要:
A semiconductor device has a flipchip semiconductor die mounted to a first substrate using a plurality of first bumps. An opening or plurality of openings is formed in the first substrate in a location central to placement of the flipchip semiconductor die to the first substrate. A plurality of semiconductor die is mounted to a second substrate. The semiconductor die are electrically connected with bond wires. An encapsulant is over the plurality of semiconductor die and second substrate. The second substrate is mounted to the first substrate with a plurality of second bumps. An underfill material is dispensed through the opening in the first substrate between the flipchip semiconductor die and first substrate. The dispensing of the underfill material is discontinued as the underfill material approaches or reaches a perimeter of the flipchip semiconductor die to reduce bleeding of the underfill material. The underfill material is cured.

摘要:
A method and an apparatus are provided for performing waveform analysis on physiological parameters. In one embodiment, a method includes reading measurement values of a first physiological parameter relating to time, and displaying them as a trend display graph in a trend display area that includes first coordinates representing time and second coordinates representing the measurement values. The method also includes acquiring a time selected in the trend display graph, and displaying, in a waveform display area, waveform data of a second physiological parameter associated with formation of the first physiological parameter during periods before and after the selected time. The waveform display area includes time coordinates. The disclosed embodiments allow medical staff to view the curve of a patient's physiological parameters throughout a monitoring/therapy period. Medical staff may make a detailed analysis of the waveform data in real time, which may provide a basis for making decisions in the following therapy processes.
