AM62x supports multimedia components such as GPU, dual Display and Camera. Assuming the worst-case scenario where all 3 are run in parallel below is the calculation : 1) OV5640 camera sensor supports 1920x1080 resolution -> 1920 width x 1080 height x 2 bytesperpixel x 8 buffers (default in yavta) : 32MiB 2) 1920x1200 Microtips LVDS panel supported -> 1920 width x 1080 height x 4 bytesperpixel x 2 buffers : 16 MiB 3) 1920x1080 HDMI display supported -> 1920 width x 1080 height x 4 bytesperpixel x 2 buffers : 15.82 MiB which is ~16 MiB 4) IMG GPU shares with display allocated buffers while rendering but in case some dedicated operation viz color conversion, keeping same window of ~16 MiB for GPU too. Total is 80 MiB and adding 32 MiB for other peripherals and extra 16 MiB to keep as buffer for fragmentation thus rounding total to 128 MiB.

AM62ax has different multimedia components such as Camera, Display, H.264 VPU and JPEG Encoder which use CMA for buffer allocations. The 12x 720x480 realtime VPU decode use-case requires 544MiB of CMA, additional 32MiB is kept as buffer in case some other peripheral also require it while VPU is running. The reason to choose latter 1GiB is to not overlap with existing memory map which is utilizing initial 1GiB for remoteproc firmwares as shared here [1]. Also some drivers such as JPEG require 32bit addressing so not allocating from higher DDR address.
