Video Stream Scaler

I tried to upscale a video stream with a factor of 2 in each dimension. Can sameone say if he implement this core with real video? because I encoutered some issues with video stream. I genererate a start signal during the sychroframe is low, and this signals erases rams, and stop the last lines transmission.

I tried to upscale a video stream with a factor of 2 in each dimension. Can sameone say if he implement this core with real video? because I encoutered some issues with video stream. I tried top upscale a 103 by 103 video to 206 by 206, and I achieve to have a 206 by 200 video size output.The last lines are deleted / stopped. I genererate a start signal during the sychroframe is low, and this signals erases rams, and stop the last lines transmission.

Is that possible to upscale by 2( in each dimension) without erasing the last lines?

Is there a minimum time between each frame (in function of the line size) or we can change some parameters.

Thanks

What is your deadtime between lines and between frames? I have implemented this core with real video on an FPGA and it works. The testbench also demonstrates the core working properly.

Hi, My deadtime is 3 clock cycle between lines and LineSize*clock cycle between frames. Thanks
