摘要:
A computer-implemented method, an accelerator hardware unit, and an article of manufacture for supporting virtual machine migration. The method includes: acquiring a task request from a task queue of an accelerator hardware unit; extracting identification information of a related virtual machine from the task request; determining whether the identification information of the related virtual machine matches the identification information of a virtual machine to be migrated, where the identification information of a virtual machine to be migrated is recorded in a virtual machine identification information table; and deleting the task request from the task queue if the extracted identification information matches the identification information of a virtual machine to be migrated.

A method, a memory controller and a processor architecture for protecting an application in a memory are disclosed. The application is cached as memory lines according to a size of a cache line. For example, the method comprises: in response to a load access request from a processor, reading from the memory a flagged memory line and an ECC checksum corresponding to the memory line, wherein the flagged memory line is obtained by performing a logic operation on a predetermined bit of the memory line and a flag bit for identifying the memory line; performing an ECC check on the flagged memory line by using the ECC checksum to obtain a value of the flag bit of the memory line; restoring the flagged memory line to the memory line according to the value of the flag bit; and determining whether or not to load the memory line according to the value of the flag bit and the type of the load access request from the processor.

摘要:
A method of reading code symbols using a digital image capture and processing system which includes: an image formation and detection subsystem; an illumination subsystem; an illumination control subsystem; a digital image processing subsystem; and an input/output subsystem; and a system control subsystem. In the illustrative embodiment, a micro-computing platform implements the digital image processing subsystem, the input/output subsystem and the system control subsystem. The micro-computing platform includes a microprocessor, a memory architecture, and a multi-tier modular software architecture responsive to the generation of a triggering event within the system. Triggering events can be generated by an automatic object detector or by a manually actuated trigger switch.

A digital-imaging based code symbol reading system comprising an image sensing array with a field of view (FOV), an illumination subsystem with an LED illumination array, an automatic illumination measurement subsystem, an illumination control subsystem, and programmed imager processor supporting an image-processing based illumination metering program. The automatic illumination measurement subsystem, employing a photodetector operating independently from the image sensing array, is used to automatically measure the illumination level at a particular region of the FOV and determine the illumination duration necessary to achieve a desired spatial intensity in the detected digital image. The illumination metering program automatically analyzes and measures, in real-time, the spatial intensity distribution of the digital image and determines whether or not a corrected illumination duration is required or desired when detecting the next or subsequent digital images, during the current or subsequent object illumination and imaging cycle. The previously determined illumination duration is over-written with the corrected illumination duration, which is used to drive the illumination subsystem and form and detect subsequent digital images of the illuminated object.

A hand-supportable automatic digital imaging-based bar code symbol reading device comprises: an automatic object presence detection subsystem; an area-type image formation and detection subsystem having a narrow-area image-capture mode of operation; a LED-based illumination subsystem having narrow-area illumination mode of operation; an image capturing and buffering subsystem; and an image-processing bar code symbol reading subsystem. The automatic object presence detection subsystem automatically detects an object, and the LED-based illumination subsystem automatically illuminates the detected object in a field of narrow-area narrow-band illumination, while the area-type image formation and detection subsystem captures a narrow-area image thereof. The image-processing bar code symbol reading subsystem automatically and directly applies decode image processing operations on the captured image, in an outwardly-directed manner, referenced from the center of the captured narrow-area image, to automatically read a 1D bar code symbol on the detected object.

The digital imaging-based bar code reading device employs a multi-mode bar code symbol reading image processor that is dynamically reconfigurable in response to real-time image analysis carried out upon captured narrow and wide area images.
