Burst boundaries on Frame Buffer

When the VIP frame buffer packs the video data into memory words, it does not always utilize all of the bits. For example, if the master port width is 32 bit and the pixels are 24 bit, 8 bits of every word are wasted.

I suspect your master port width is 128 bit. In this case, 5 pixels (120 bits) will be packed into each 128 bit word.

In this case, the required memory for one frame of video data would be approximately:

512*384*3*128/120 = 629145.6 bytes

Round this up to the nearest word side size and multiply by three frames:

629152 * 3 = 1887456 bytes = 1843.2 kbytes
