Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms used in the present invention are to be interpreted.
VGA: video graphics array Video image array
AXI: advanced eXtensible Interface high-performance expansion bus
FIFO: first Input First Output cache
FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The implementation body in fig. 1 may be a video extraction frame loss control system.
As shown in fig. 1, the method 100 includes:
and 150, if not, discarding the currently read image frame.
In order to facilitate understanding of the present invention, the video extraction frame loss control method provided by the present invention is further described below by using the principle of the video extraction frame loss control method of the present invention and combining the process of performing frame loss control on video extraction in the embodiment.
Specifically, the video extraction frame loss control method includes:
and S1, the monitoring VGA writes the video data into the memory.
The video extraction process of the invention reads the video data in the memory through the AXI high-performance expansion bus, the memory end of the high-performance expansion bus is AXI slave, and the AXI master initiates active communication to the AXI slave through the AXI master end of the high-performance expansion bus, thereby reading the video data in the memory.
And monitoring whether the VGA writes video data into the memory or not, if the VGA starts to write data into the memory, receiving a cap _ start signal, indicating that a condition for executing video extraction is met, and starting to execute the video extraction, otherwise, not executing the video extraction.
And S2, acquiring the frame rate of video extraction.
And extracting the frame rate of video extraction from the received video extraction instruction. The AXI Master module starts to form an address according to the resolution information (resolution _ num/base _ address/size/frame _ rate) transmitted by the control module and initiates an AXI Read operation.
S3, judging whether the interval between the currently read image frame and the recently extracted image frame meets the frame rate: if yes, extracting the currently read image frame and storing the image frame in a buffer device (FIF 0); and if not, discarding the currently read image frame.
Each time one data is read, the read data number counter cap _ cnt is incremented by one, indicating the number of data currently read. Then, according to the frame rate frame _ rate extracted in step S2, it is determined whether the interval between the currently read image frame and the most recently extracted image frame satisfies the frame rate to determine whether the currently read frame is lost, and if so, the write enable signal FIFO _ wen of the FIFO is set to 0, and the writing of data into the FIFO is prohibited, but at this time, the AXI still performs the operation of reading the memory data. And if the current frame does not need to be dropped, storing the current frame into the FIFO.
And S4, inserting the frame head and the frame tail.
When the reading of the memory data is started, when the cap _ cnt is equal to 0, the operation of writing the FIFO is controlled, a Header flag is written into the FIFO to indicate the start of a frame, and then the data read by the AXI bus is written into the FIFO. When the cap _ cnt is equal to the resolution number (resolution _ num), the FIFO write is controlled to write an End flag into the FIFO, indicating the End of a frame. After inserting the frame head and tail mark into the FIFO, the AXI Master continues to read the memory data.
S5, writing data into the FIFO under the AXI clock domain, reading data from the FIFO under the system clock domain and inputting the read data to the video compression module. Let FIFO _ num indicate the amount of data present in the current output FIFO. Two thresholds are set at this time, Max _ throdhold and Min _ throdhold, representing the thresholds for FIFO _ num being full and empty immediately, respectively. When the data quantity FIFO _ num in the FIFO is larger than Max _ throdhold, which indicates that the FIFO reading speed of the subsequent module is slower than the data writing speed of the AXI Master to the FIFO, the memory reading action of the AXI Master is stopped at this time, and the data are not written into the FIFO. When the subsequent module continuously reads the data in the FIFO and the number of FIFO _ num in the current FIFO is less than Min _ throdhold, it indicates that the subsequent module is about to read the FIFO empty immediately, and at this time, the operation of reading the memory data by the AXI Master is restarted. And then, judging whether the operation of stopping video extraction is received or not, if the operation is stopped, ending the whole flow, and if the operation is not ended, continuing the operation of reading the memory of the AXI Master.
