摘要:
A processing system that interacts with external devices has a processor, a memory, and a controller. The memory stores templates that provide access protocol information about the external devices. When an external device is to be accessed, the operating system, which is stored in the memory, instructs the processor to perform the access to the external device. The processor puts the information about the external device on the address portion of the system bus where it is received and interpreted by the controller. The controller in turn retrieves the template for the external device as indicated by the information that was received. After retrieving the template, the controller outputs the information, in the manner indicated by the template, on an external interface bus where the external device is also coupled. The external device then responds according to the information that the controller put on the external interface bus.

A system and method for filtering a frame, the method includes: (i) processing, by a processing unit executing instructions, at least one portion of a frame to provide at least one processed frame portion; (ii) performing, by a hardware filter, deblocking filtering of the at least one processed frame portion to provide at least one filtered frame portion; and (ii) storing the at least one filtered frame portion in a memory unit that is accessible by the processing unit; whereas the stage of processing is responsive to previously filtered frame portions. The system includes: (i) a processing unit, adapted to execute instructions such as to process at least one portion of a frame to provide at least one processed frame portion; (ii) a hardware filter, connected to the processing unit, adapted to deblocking filter the at least one processed frame portion to provide at least one filtered frame portion; and (iii) a memory unit, connected to the processing unit, adapted to store the at least one filtered frame portion; whereas the processing unit is adapted to process the at least one portion in response to previously filtered frame portions.

A system and method for displaying a sequence of image frames, the system includes: (i) a first circuitry, adapted to receive a sequence of image frames at an update rate (Ur), the sequence of image frames is associated with a sequence of update synchronization signals; and (ii) a second circuitry, adapted to control a display the sequence of images at a refresh rate (Rr), whereas Rr=Ur*[(N+1)/N]; whereas the sequence of images are associated with a sequence of refresh synchronization signals that driven from the update synchronization signals. The method includes: (i) receiving a sequence of image frames at an update rate (Ur), the sequence of image frames is associated with a sequence of update synchronization signals; and (ii) displaying the sequence of images at a refresh rate (Rr), whereas Rr=Ur*[(N+1)/N]; whereas the sequence of images are associated with a sequence of refresh synchronization signals that driven from the update synchronization signals.
