    摘要: In a multiprocessor system, a primary processor may store an executable image for a secondary processor. A communication protocol assists the transfer of an image header and data segment(s) of the executable image from the primary processor to the secondary processor. Messages between the primary processor and secondary processor indicate successful receipt of transferred data, termination of a transfer process, and acknowledgement of same.

    摘要: In a multi-processor system, an executable software image including an image header and a segmented data image is scatter loaded from a first processor to a second processor. The image header contains the target locations for the data image segments to be scatter loaded into memory of the second processor. Once the image header has been processed, the data segments may be directly loaded into the memory of the second processor without further CPU involvement from the second processor.

    摘要: A signal compression optimization system between a communication network and wireless user equipment advantageously selects an optimized decompressor when feasible for reduced content processing latency and otherwise selects a virtual machine decompressor, such as a Universal Decompressor Virtual Machine (UDVM) that interprets the received decompression bytecode. Since the UDVM is not optimized for any particular decompression algorithm and suffers by the requisite delays associated with analyzing each statement in the bytecode before execution, being able to avoid use of the UDVM whenever possible enhances user experience in presenting wirelessly received signaling messages or media content.

    摘要: A universal serial bus (USB) device communicates with a USB host over a USB to remotely wake up the USB host over the USB when the USB host is in a low power (e.g. deep sleep) mode. The USB device performs an activity to wake up the USB host. The USB host performs a remote wake up process in response to detecting the activity by the USB device. The USB host performs a resume process in response to performing the remote wake up process by the USB host. The USB device wakes up in response to the USB host performing the resume process.

    摘要: Disclosed are apparatus and methods for use in a USB device with multiple processors, allowing shared USB connectivity in the device. The disclosed apparatus and methods allow selective coupling of a first processor to a USB port of the device or to a USB hub operable to route a plurality of USB connections including connection of a second processor to the port. Providing selective coupling of the processors to the port by switching the coupling of the first processor and selectively powering the hub on and off for selective coupling of the second processor, thereby selectively enabling tethered networking such as wireless networking, affords increased power savings in the device. Furthermore, default coupling of the first processor to the port allows for USB battery charger detection, or direct connectivity to USB peripheral devices, as well as providing programming capability via the default coupling of the port to the first processor.
