How do I change the motion threshold for the Deinterlacer II MegaCore function (with Sobal based HQ mode)? - How do I change the motion threshold for the Deinterlacer II MegaCore function (with Sobal based HQ mode)? Description The number of motion threshold bits for the Deinterlacer II MegaCore® function can be modified manually by following these steps - Locate the function’s source file in the synthesis/submodules directory. It will be named similar to: <my_deinterlacer_name>_alt_vip_cl_dil_0.v – Then find the instantiation of the motion detect block which will look like this: alt_vip_motion_detect #( .BITS_PER_SYMBOL (8), .NUMBER_OF_COLOR_PLANES (2), .COLOR_PLANES_ARE_IN_PARALLEL (1), .MAX_LINE_LENGTH (1920), .KERNEL_SIZE_0 (4), .KERNEL_SIZE_1 (1), .KERNEL_SIZE_2 (2), .KERNEL_SIZE_3 (1), .MOTION_BPS (7), // Try reducing to ~4 .SRC_WIDTH (8), .DST_WIDTH (8), .CONTEXT_WIDTH (8), .TASK_WIDTH (8), .SOURCE_ADDRESS (0) ) - Change the “MOTION_BPS” parameter. The MOTION_BPS parameter is used for motion detection as follows : if (MOTION_BPS > BITS_PER_SYMBOL) assign normalized_motion[i] = absdiff[i] << (MOTION_BPS-BITS_PER_SYMBOL); else assign normalized_motion[i] = absdiff[i][BITS_PER_SYMBOL-1 -: MOTION_BPS]; Do not re-generate the Qsys system after manually editing, as the change will be overwritten by Qsys.
