A second semiconductor die is provided that has a second bulk semiconductor side and a second opposite side. The second opposite side of the second semiconductor die is coupled to the first opposite side of the first semiconductor die. Electrical connections are formed between the first semiconductor die and the second semiconductor die.
Abstract:
Embodiments of a power consumption reduction process for memory interfaces are described. A power management process reduces the amount of time that current flows in a high or low terminated, current or voltage mode unipolar bus interface by reducing the amount of time the bus remains in a logic state that requires current flow.
Abstract:
A system and method for applying non-homogeneous properties to multiple video processing units (VPUs) in a multiple VPU system are described. Respective VPUs in the system cooperate to produce a frame to be displayed. In various embodiments, data output by different VPUs in the system is combined, or merged, or composited to produce a frame to be displayed. In load balancing modes, each VPU in the system performs different tasks as part of rendering a same frame, and therefore typically executes different commands. In various embodiments, efficiency of the system is enhanced by forming a single command buffer for execution by all of the VPUs in the system even though each VPU may have a different set of commands to execute in the command buffer.
Abstract:
A method of operating a shared bus comprises sending a wake-up signal on the shared bus. The wake-up signal comprises a sequence of signals, each signal of the sequence being one of a signal indicating the bus is free and a signal indicating the bus is busy. A microcontroller to effect this method is also contemplated. A wake-up device for a shared bus has a first latch to recognise a signal indicating one of said shared bus being free and said shared bus being busy and selectively output a recognition signal and a second latch to, after receipt of the recognition signal, recognise a signal indicating another of the shared bus being free and Ihe shared bus being busy and selectively output a power-on signal. The latches may be D -type flip flops.
Abstract:
A method and apparatus for communicating compressed video information includes storing video information compressed based on a first compression method, such as a method with a high compression ratio, and transcoding the compressed video information to produce corresponding recompressed video information that is based on a second compression method, with a lower compression ratio such as standard JPEG compression or other suitable compression. The method and apparatus, if desired, may include sending the recompressed video information for a destination apparatus which may then suitably decompress the video information using a standard decompression technique. For example, storing the compressed image in a high compressed format, for example, in a piecewise basis may be done online while the camera, for example, is in use so that the image is properly captured and then, transcoding the compressed image to a different level of compression while the camera is offline.
Abstract:
A computer able to execute programs coded in either of two binary instruction sets. Memory is divided into regions, and each region is marked to indicate which of the two instruction sets are to be used to execute instructions fetched from that region. The native operating system manages contexts so that the operating system for the guest instruction set architecture can context switch, even if the process being context-switched out is a process in the native instruction set. Code in the guest instruction set is profiled to determine which portions are most profitably translated into the native instruction set. Circuitry recognizes when execution of a binary in the guest instruction set has reached a flow point for which a translated native equivalent exists. Concurrency controls protect the translated native code against modification by self-modifying code or DMA writes.

Various semiconductor chip conductor structures and methods of fabricating the same are provided. In one aspect, a method of manufacturing is provided that includes forming a conductor structure on a semiconductor chip. The conductor structure has a first site electrically connected to a first redistribution layer structure and a second site electrically connected to a second redistribution layer structure. A solder structure is formed on the conductor structure.
Abstract:
To receive new services including audio or video content for presentation by a cable-compatible digital television or other digital audio/video receiver, a module may be connected to the HOST-POD interface of the digital television. The module has a receiver for receiving audio or video content in a first compression format, a transcoder for converting said audio or video content from the first compression format into a second, different compression format, and a controller for transmitting the audio or visual content in the second compression format to the digital television over a HOST-POD interface. By using such a module, front-end components of the digital television may be bypassed while back-end components may be utilized to decompress and present the content. The module may be a PC card or smart card for example.
Abstract:
To provide for the processing of priority data elements between a host processor and a co- processor that exchange such data elements using a queue, the host processor determines a priority of a data element received from an application. If the priority is higher than a lowest possible priority value, at least one lower priority data element within the queue may be identified and modified thereby temporarily removing it from the queue. When the priority data element is written into the queue a query packet is included that will cause the co-processor to return information regarding a last executed queued data element. Based on the returned information, the host processor can determine one or more unmodified data elements (uniquely corresponding to the one or more modified queued data elements) to be written into the queue in accordance with a sequence of the previously modified queued data elements.
Abstract:
A system and method for frame synchronization in multiple video processing unit (VPU) systems is described. In various embodiments, multiple VPUs cooperatively process frame data for display. According to embodiments, more than one VPU may not reside on a same card such that conventional synchronization methods are available. Frame data synchronization is accomplished in various embodiments by using semaphore mechanisms and by writing values to shared memory locations. For synchronization of execution among multiple VPUs operating on a same command buffer, execution of commands by one or more VPUs is stalled based on a semaphore value or a value in a shared memory location.
