The first half of the registers contain one row, while the second // half of a register contains the second-next row (also stored in the first // half of the register two steps ahead). The convolution does two outputs // at a time; the output of v17-v24 into one, and v18-v25 into another one. // The first half of first output is the first output row, the first half // of the other output is the second output row. The second halves of the // registers are rows 3 and 4. // This only is designed to work for 4 or 8 output lines. .macro do_8tap_4v type, idx1, idx2 function \type\()_8tap_4v_\idx1\idx2 sub x2, x2, x3, lsl #1 sub x2, x2, x3 ld1 {v0.8b}, [x6] sxtl v0.8h, v0.8b .ifc \type,avg mov x7, x0 .endif ld1 {v1.s}[0], [x2], x3 ld1 {v2.s}[0], [x2], x3 ld1 {v3.s}[0], [x2], x3 ld1 {v4.s}[0], [x2], x3 ld1 {v5.s}[0], [x2], x3 ld1 {v6.s}[0], [x2], x3 trn1 v1.2s, v1.2s, v3.2s ld1 {v7.s}[0], [x2], x3 trn1 v2.2s, v2.2s, v4.2s ld1 {v26.s}[0], [x2], x3 uxtl v17.8h, v1.8b trn1 v3.2s, v3.2s, v5.2s ld1 {v27.s}[0], [x2], x3 uxtl v18.8h, v2.8b trn1 v4.2s, v4.2s, v6.2s ld1 {v28.s}[0], [x2], x3 uxtl v19.8h, v3.8b trn1 v5.2s, v5.2s, v7.2s ld1 {v29.s}[0], [x2], x3 uxtl v20.8h, v4.8b trn1 v6.2s, v6.2s, v26.2s uxtl v21.8h, v5.8b trn1 v7.2s, v7.2s, v27.2s uxtl v22.8h, v6.8b trn1 v26.2s, v26.2s, v28.2s uxtl v23.8h, v7.8b trn1 v27.2s, v27.2s, v29.2s uxtl v24.8h, v26.8b uxtl v25.8h, v27.8b convolve v1, v2, v17, v18, v19, v20, v21, v22, v23, v24, v25, \idx1, \idx2, v3, v4 do_store4 v1, v2, v5, v6, \type subs x4, x4, #4 b.eq 9f ld1 {v1.s}[0], [x2], x3 ld1 {v2.s}[0], [x2], x3 trn1 v28.2s, v28.2s, v1.2s trn1 v29.2s, v29.2s, v2.2s ld1 {v1.s}[1], [x2], x3 uxtl v26.8h, v28.8b ld1 {v2.s}[1], [x2], x3 uxtl v27.8h, v29.8b uxtl v28.8h, v1.8b uxtl v29.8h, v2.8b convolve v1, v2, v21, v22, v23, v24, v25, v26, v27, v28, v29, \idx1, \idx2, v3, v4 do_store4 v1, v2, v5, v6, \type 9: ret endfunc .endm do_8tap_4v put, 3, 4 do_8tap_4v put, 4, 3 do_8tap_4v avg, 3, 4 do_8tap_4v avg, 4, 3 .macro do_8tap_v_func type, filter, offset, size function ff_vp9_\type\()_\filter\()\size\()_v_neon, export=1 uxtw x4, w4 movrel x5, X(ff_vp9_subpel_filters), 120*\offset - 8 cmp w6, #8 add x6, x5, w6, uxtw #3 mov x5, #\size .if \size >= 8 b.ge \type\()_8tap_8v_34 b \type\()_8tap_8v_43 .else b.ge \type\()_8tap_4v_34 b \type\()_8tap_4v_43 .endif endfunc .endm .macro do_8tap_v_filters size do_8tap_v_func put, regular, 1, \size do_8tap_v_func avg, regular, 1, \size do_8tap_v_func put, sharp, 2, \size do_8tap_v_func avg, sharp, 2, \size do_8tap_v_func put, smooth, 0, \size do_8tap_v_func avg, smooth, 0, \size .endm do_8tap_v_filters 64 do_8tap_v_filters 32 do_8tap_v_filters 16 do_8tap_v_filters 8 do_8tap_v_filters 4
