Description
Technical field
The present invention relates to technical field of data transmission, relate in particular to a kind of data transportation processing method and device.
Background technology
Direct memory access (Direct Memory Access, DMA) be a kind of mode of operation of carrying out data-moving fully by hardware, under the DMA pattern, dma controller is carried out the data-moving operation by a bus master controller that is independent of processor, CPU only needs to assign instruction to dma controller, allow dma controller come the transmission of deal with data, do not need through CPU, data just can be directly between storer, move between the peripheral hardware and between internal memory and the I/O equipment, Data Transfer Done is given CPU information feedback again.
When carrying out the encoding and decoding of audio or video, often need carry in enormous quantities data, usually, adopt the DMA form that audio, video data is carried.
Because the placement of video raw data in internal memory be very inconvenient to the processing of data, therefore, raw data need be rearranged and to make things convenient for processing.As shown in Figure 1, left data is the video raw data of obtaining from the video inputs mouth, is to leave in the storer according to the order of obtaining, but when deal with data, Rx, Gx, Bx data need be rearranged the order on the right.N Rx data are arranged, therefore adopt existing DMA technology to carry out data-moving, CPU must carry out the position that n configuration could be moved all Rx to the right to DMA.All R, G, B data rearrangement will be classified as the order on the right, CPU just must carry out 3n configuration to DMA, and this will reduce the performance of main CPU system greatly; Perhaps embed a small-sized microprocessor again, finish the data carrying by the mode that small-sized microprocessor is programmed in DMA inside.
When voice data transmitted by digital link (as I2S), it may comprise several passages.These passages must be multiplexing in a data line, by same serial port transmission.At this moment, DMA can handle with multiplexing data are deinterleaved (interleaving), so that allow each channel data line spread on storer.In Fig. 2, the left side is the voice data of the left and right acoustic channels handled, and separately L channel and R channel are placed.But when sending the data of left and right acoustic channels, the data interlacing of left and right acoustic channels need be sent together by the I2S bus.If use the DMA carrying, do not optimizing under the situation that voice data moves, whenever moving a channel data all needs DMA of CPU configure, carries n data and then need dispose 2n time DMA; Perhaps embed a small-sized microprocessor again, finish the data carrying by the mode that small-sized microprocessor is programmed in DMA inside.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art:
When audio or video The data DMA pattern was carried out the permutatation of data, before each data of carrying, CPU need carry out a DMA configuration, can take cpu resource greatly like this, reduces the efficient of system.
