    摘要: A motion sequence pattern detector (300,301) for detecting presence of film material in a series of consecutive video fields (pp,p,c), is arranged to compute for a first one of the consecutive fields a value of a video motion measure and a value of a film motion measure and to determine the presence of film material on basis of both motion measures. The value of the video motion measure is computed by: establishing a plurality of motion patterns for respective groups of pixels of the first one of the consecutive fields; comparing each of the plurality of motion patterns with a predetermined video motion pattern and conditionally increasing the value of the video motion measure. The value of the film motion measure is computed by comparing each of the plurality of motion patterns with a predetermined film motion pattern and conditionally increasing the value of the film motion measure.

    摘要: Video stream processing, such as processing that includes MPEG decoding an subsequent post-processing involves using signal processing circuitry (102, 106) to execute a first and a second video stream processing function. The first video stream processing function produces frame data of successive video frames in a temporally ordered output sequence of frames. The second video stream processing function uses the frame data in an ordered input sequence of frames that differs from the output sequence, for example because later P-frames are needed to decode B frames. The frame data is buffered between application of the first and second video processing function to the frame data. A first and a second. buffer memory (12, 106) are used. The first buffer memory (12) is coupled to the signal processing circuitry via a shareable channel (15) such as an external IC terminals, but the processing circuitry does not use the shareable channel (15) to access the second buffer memory (106). The second video processing function reads frame data from first and second ones of the frames selectively from the first and second buffer memory (12, 106) respectively. The second ones of the frames occur in the same temporal order in both the input and output sequence. The first ones of the frames contain at least all particular frames whose position relative to the second ones of the frames in the output sequence differs from the position of the particular frames relative to the second ones of the frames in the input sequence.

    摘要: Programmable platforms include components such as a central processing unit (CPU), coprocessors (COP I, COP2), and a shared system bus (SB) that connects the various processors. In media processing applications, the processing of the functions is distributed to the central processing unit and the coprocessors. Such functions may be effected in hardware, in software, or in a mixture thereof. The utilization of each coprocessor may vary both for different applications as well during execution of a single application, depending on the character of the media processing application. As a result, one or more coprocessors may not be effectively utilized during a certain part of the media processing. In case of a synchronous system those coprocessors continue consuming power. According to the invention, a coprocessor can be powered down by a local controller, depending on the workload of that coprocessor. As a result, power control is distributed and automatic, and only depends on required processing capacity of the coprocessor.

    摘要: The invention provides an integrated circuit comprising a data processing system which performs satisfactorily after integration of the individual building blocks, such as main processors and coprocessors, into the data processing system. This is achieved by measuring the utilization of the communication structure established between the individual building blocks. A measurement unit measures properties of the communication load by observing the communication traffic on connections between processing units and a communication resource, or on connections within the communication resource. The measurement unit performs statistical operations on the observed properties and produces measurement results. The measurement results can be retrieved by measurement software and can be used to modify the data processing system, for example by debugging or by adaptive control.
