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 q5-q12 into one, and q4-q13 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 r2, r2, r3, lsl #1 sub r2, r2, r3 vld1.8 {d0}, [r12, :64] vmovl.s8 q0, d0 vld1.32 {d2[]}, [r2], r3 vld1.32 {d3[]}, [r2], r3 vld1.32 {d4[]}, [r2], r3 vld1.32 {d5[]}, [r2], r3 vld1.32 {d6[]}, [r2], r3 vld1.32 {d7[]}, [r2], r3 vext.8 d2, d2, d4, #4 vld1.32 {d8[]}, [r2], r3 vext.8 d3, d3, d5, #4 vld1.32 {d9[]}, [r2], r3 vmovl.u8 q5, d2 vext.8 d4, d4, d6, #4 vld1.32 {d28[]}, [r2], r3 vmovl.u8 q6, d3 vext.8 d5, d5, d7, #4 vld1.32 {d29[]}, [r2], r3 vmovl.u8 q7, d4 vext.8 d6, d6, d8, #4 vld1.32 {d30[]}, [r2], r3 vmovl.u8 q8, d5 vext.8 d7, d7, d9, #4 vmovl.u8 q9, d6 vext.8 d8, d8, d28, #4 vmovl.u8 q10, d7 vext.8 d9, d9, d29, #4 vmovl.u8 q11, d8 vext.8 d28, d28, d30, #4 vmovl.u8 q12, d9 vmovl.u8 q13, d28 convolve q1, q2, q5, q6, q7, q8, q9, q10, q11, q12, q13, \idx1, \idx2, q4, q3 do_store4 q1, d2, q2, d4, d3, d5, \type subs r4, r4, #4 beq 9f vld1.32 {d2[]}, [r2], r3 vld1.32 {d3[]}, [r2], r3 vext.8 d29, d29, d2, #4 vext.8 d30, d30, d3, #4 vld1.32 {d2[1]}, [r2], r3 vmovl.u8 q14, d29 vld1.32 {d3[1]}, [r2], r3 vmovl.u8 q15, d30 vmovl.u8 q5, d2 vmovl.u8 q6, d3 convolve q1, q2, q9, q10, q11, q12, q13, q14, q15, q5, q6, \idx1, \idx2, q4, q3 do_store4 q1, d2, q2, d4, d3, d5, \type 9: vpop {q4-q7} pop {r4-r5} bx lr 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 push {r4-r5} vpush {q4-q7} ldr r4, [sp, #72] movrelx r12, X(ff_vp9_subpel_filters), r5 ldr r5, [sp, #80] add r12, r12, 120*\offset - 8 add r12, r12, r5, lsl #3 cmp r5, #8 mov r5, #\size .if \size >= 8 bge \type\()_8tap_8v_34 b \type\()_8tap_8v_43 .else bge \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
