Techniques for selectively updating regions of a display are disclosed. In the illustrative embodiment, a display engine of a computing device sends messages to a display to update particular update regions of the display. As not the entire frame is sent, sending only the update regions can save bandwidth and power. In the illustrative embodiment, some of the update regions for a frame sent to the display may be compressed and some of the update regions for the frame may be uncompressed. Due to overhead in the compression, sending small update regions uncompressed may reduce the bandwidth and/or power used.

Technologies for selective frame update on a display

Examples described herein relate to a graphics processing system that includes one or more integrated graphics systems and one or more discrete graphics systems. In some examples, an operating system (OS) or other software supports switching between image display data being provided from either an integrated graphics system or a discrete graphics system by configuring a multiplexer at runtime to output image data to a display. In some examples, a multiplexer is not used and interface supported messages are used to transfer image data from an integrated graphics system to a discrete graphics system and the discrete graphics system generates and outputs image data to a display. In some examples, interface supported messages are used to transfer image data from a discrete graphics system to an integrated graphics system and the integrated graphics system uses an overlay process to generate a composite image for output to a display.

Switchable image source in a hybrid graphics systems

An apparatus for managing input/output (I/O) data may include a streaming I/O controller to receive data from a load/store domain component and output the data as first streaming data of a first data type comprising a first data movement type and first data format type. The apparatus may also include at least one accelerator coupled to the streaming I/O controller to receive the first streaming data, transform the first streaming data to second streaming data having a second data type different than the first data type, and output the second streaming data. In addition, the apparatus may include a streaming interconnect to conduct the second data to a peer device configured to receive data of the second data type.

Scalable input/output system and techniques to transmit data between domains without a central processor

According to various embodiments, apparatuses and methods to communicate buffer allocation information are presented. The disclosed apparatuses and methods may include transmitting a buffer message by a wireless USB device to a wireless USB host, which may indicate an available storage space in a buffer of the USB device to store data from the USB host. The buffer message may be transmitted independent of whether or not the USB device has received a request message (e.g., from the USB host) for information relating the available storage space in the buffer. Additionally, the buffer message may be transmitted independent of any data exchange mechanism between the USB host and the USB device. The USB device may receive a data packet from the USB host, and transmit a data packet acknowledgement message including data packet status information, and information regarding the available storage space in the buffer.

Buffer-related USB communication

Methods, apparatuses and storage medium associated with migration between processors by a computing device are disclosed. In various embodiments, a portable electronic device having an internal processor and internal memory may be attached to a dock. The dock may include another processor as well other memory. The attachment of the dock to the portable electronic device may cause an interrupt. In response to this interrupt, a state associated with the internal processor may be copied to the other memory of the dock. Instructions for the computing device may then be executed using the other processor of the dock. Other embodiments may be disclosed or claimed.

Execution context migration method and apparatus

An example apparatus includes: a host controller offload capability detector to determine that a media stream offload capability is available in the peripheral interface host controller; a media stream offload arbiter to send a media stream offload request to a media processor manager based on the media stream offload capability and based on a peripheral device being connected to the peripheral interface host controller; and an endpoint mapper to generate an endpoint table entry corresponding to the peripheral device, the endpoint table entry to assign a first communication interface of the peripheral interface host controller to transfer a media stream corresponding to the peripheral device between the media processor and the peripheral interface host controller without the media stream being routed to an application processor that is in circuit with the peripheral interface host controller and in circuit with the media processor.

Methods and apparatus to offload media streams in host devices

A method of and apparatus for communicating between a host and an agent. The method includes the step of performing a first transaction between a host controller and a hub. The hub is operable to perform a single transaction with an agent based on the first transaction. The method then includes the step of performing a second transaction between the host controller and the hub. The second transaction is based on the single transaction.

Split transaction protocol for a bus system

An apparatus for processing visual information includes a controller to control display of information in an application window based on first visual information stored in a buffer and second visual information received from one or more sources. The controller outputs the first visual information for display in a first area of the application window and outputs the second visual information for simultaneous display in a second area of the application window. The first visual information is visual information that does not change between a first time and a second time, and the second visual information is visual information that changes between the first time and the second time. The controller may be different from a central processing unit of a host device.

System and method for processing visual information

Embodiments comprising a memory and a USB host controller coupled to the memory. The power efficiency of a USB during asynchronous transfers is increased by limiting usage of an asynchronous schedule stored in the memory when servicing a scheduled asynchronous transfer endpoint. Other embodiments may be described and claimed.
