I use the frame reader in my design with the following settings:
Bits per pixel per color plane: 8 Number of color planes in parallel: 3 Number of color planes in sequence: 1 Maximum Image width: 1920 Maximum Image height: 1080 Master port width: 64 Read master FIFO depth: 1024 Read master FIFO burst target: 64 Use separate clock for the Avalon MM master interface: unchecked Kindly confirm if the following calculations for number the words and the Single Cycle Color Patterns are true or not 1- // Words IOWR(FRAMEREADER_BASE, 5, 259200); // (1920*1080*8*3)/48= 1036800 2- // Single Cycle Color Patterns IOWR(FRAMEREADER_BASE, 6, 2073600); // 1920*1080=2073600 number of pixels in the frame multiplied by the number of single cycles required to represent one pixel Your reply will be highly appreciatedLink Copied

Why did you divide by 48?

The frame reader will only transfer whole "single cycle color patterns" (pixels). With a 64-bit master port width and 24-bit pixels, the Frame Reader will only be transferring 48 bits (not 64 bits) of picture data at a time.
