about

nx_h264_idct_gate.nx -- REFEREE for the H.264 4x4 inverse transform (rung 5-core). Hand-computed exact vectors (verified against spec 8.5.12.2): DC only: coeff[0]=256, rest 0 -> every output sample = (256+32)>>6 = 4. AC [0][1]=64, rest 0 -> every row = [1,1,0,-1] (exercises butterfly + the NEGATIVE arithmetic-shift: -64+32=-32, asr(-32,6) = -1). zero block -> all 0. add_clip: pred[100,100,100,100] + res[50,-200,300,0] -> [150,0,255,100]. Every value PRINTED. stdout + knowledge/status/h264_idct_gate.log. Exit 0/1. Sovereign: nx_syscalls + nx_h264_idct. license_tier: ORIGINAL
