摘要： A method and apparatus for the enhancing efficiency of a data processing system which includes a host microprocessor, a system memory, and a graphics adapter for producing an enhanced graphics display. The graphics adapter is coupled to the data processing system by a bus and includes a video memory and an adapter microprocessor, wherein the adapter microprocessor is less powerful than the host microprocessor in the data processing system. The method and apparatus of the present invention includes the establishment of a stage buffer from a portion of the system memory with the stage buffer, including at least two buffer sections. A first portion of data is transferred from the system memory into a first buffer section. Next, a second portion of data is transferred from the system memory into a second buffer section, while the adapter microprocessor is simultaneously retrieving the first portion of data from the first buffer section and transferring that first portion of data across the bus to the video memory, wherein host microprocessor is available to perform other tasks. When the adapter microprocessor has transferred the data to the video memory from the first buffer section, the host microprocessor fills the first buffer section with more data, while the adapter microprocessor retrieves data from the second buffer section. This process continues until all the data has been transferred.

摘要： A method and apparatus are disclosed for providing exchange of data between a peripheral device having a paging mechanism and an application operating in a virtual machine which includes a page directory for exclusive use by the paging mechanism of the peripheral device. The virtual machine is running on a data processing system and preferably contains a block of memory which is divided into various sections of memory. The page directory is provided to the paging mechanism of the peripheral device when the application requires the use of the peripheral device. A section of memory is selectively locked down in response to the section of memory being utilized by the application. Additionally, the page directory is updated with an entry which identifies the section of memory that is locked down. Memory may also be locked down in order to permit the peripheral device to access that section of memory. The page directory is selectively updated thereafter by mapping entries into the page directory in order to track memory usage within the block of memory utilized by the virtual machine. The page directory is preferably created at the same time the virtual machine is created. Memory for utilization by the virtual machine is preferably locked down while the virtual machine is in the foreground. When the virtual machine is terminated or moved into the background, the sections of memory that have been locked down are then unlocked or freed for other use.
摘要翻译：公开了一种用于在具有寻呼机构的外围设备和在虚拟机中操作的应用程序之间提供数据交换的方法和装置，所述虚拟机包括由外围设备的寻呼机构专用的寻呼目录。虚拟机在数据处理系统上运行，并且优选地包含被分成存储器的各个部分的存储器块。当应用程序需要使用外围设备时，页面目录被提供给外围设备的寻呼机制。响应于应用程序利用的存储器部分，存储器的一部分被选择性地锁定。此外，页面目录更新为一个条目，标识被锁定的内存部分。存储器也可能被锁定，以便允许外围设备访问该部分的存储器。之后通过将条目映射到页目录中来选择性地更新页目录，以便跟踪由虚拟机使用的存储器块内的存储器使用。页面目录优选地在创建虚拟机的同时创建。优选地，在虚拟机处于前台时，由虚拟机利用的存储器被锁定。当虚拟机终止或移动到后台时，锁定的内存部分然后被解锁或释放以供其他使用。

摘要： A method of generating and providing script associated with a digital asset is provided. A web application hosted on a server generates script. The script includes code to request the content of the digital asset from a remote site when the code is executed by a browser. The code includes a subscriber identifier for use by the remote site in determining whether a web page is authorized to receive the content of the digital asset. The generated script is provided to a web browser for insertion into, and to become part of, a web page. The script allows for receipt of the content of the digital asset to an authorized web page.
