In either case, only one +; pinsrw instruction can be decoded per cycle (and nothing else if they are +; back-to-back), so out-of-order execution cannot be used to work around long +; pinsrw chains (though for Sandy Bridge and later, this may be less of a +; problem if the code runs from the µop cache.) +; +; We use tzcnt instead of bsf without checking for support. The instruction is +; executed as bsf on CPUs that don't support tzcnt (encoding is equivalent to +; rep bsf.) The destination (first) operand of bsf (and tzcnt on some CPUs) is +; an input dependency (although the behavior is not formally defined, Intel +; CPUs usually leave the destination unmodified if the source is zero.) This +; can prevent out-of-order execution, so we clear the destination before +; invoking tzcnt. +; +; Initial register allocation +; eax - frame --> buffer +; ebx - nbits_base (PIC) / emit_temp +; ecx - dctbl --> size --> state +; edx - block --> nbits +; esi - code_temp --> state --> actbl +; edi - index_temp --> free_bits +; esp - t +; ebp - index + +%define frame eax +%ifdef PIC +%define nbits_base ebx +%endif +%define emit_temp ebx +%define emit_tempb bl +%define emit_temph bh +%define dctbl ecx +%define block edx +%define code_temp esi +%define index_temp edi +%define t esp +%define index ebp + +%assign save_frame DCTSIZE2 * SIZEOF_WORD + +; Step 1: Re-arrange input data according to jpeg_natural_order +; xx 01 02 03 04 05 06 07 xx 01 08 16 09 02 03 10 +; 08 09 10 11 12 13 14 15 17 24 32 25 18 11 04 05 +; 16 17 18 19 20 21 22 23 12 19 26 33 40 48 41 34 +; 24 25 26 27 28 29 30 31 ==> 27 20 13 06 07 14 21 28 +; 32 33 34 35 36 37 38 39 35 42 49 56 57 50 43 36 +; 40 41 42 43 44 45 46 47 29 22 15 23 30 37 44 51 +; 48 49 50 51 52 53 54 55 58 59 52 45 38 31 39 46 +; 56 57 58 59 60 61 62 63 53 60 61 54 47 55 62 63 + + align 32 + GLOBAL_FUNCTION(jsimd_huff_encode_one_block_sse2) + +EXTN(jsimd_huff_encode_one_block_sse2): + +%assign stack_offset 0 +%define arg_state 4 + stack_offset +%define arg_buffer 8 + stack_offset +%define arg_block 12 + stack_offset +%define arg_last_dc_val 16 + stack_offset +%define arg_dctbl 20 + stack_offset +%define arg_actbl 24 + stack_offset + + ;X: X = code stream + mov block, [esp + arg_block] + PUSH ebx + PUSH ebp + movups xmm3, XMMWORD [block + 0 * SIZEOF_WORD] ;D: w3 = xx 01 02 03 04 05 06 07 + PUSH esi + PUSH edi + movdqa xmm0, xmm3 ;A: w0 = xx 01 02 03 04 05 06 07 + mov frame, esp + lea t, [frame - (save_frame + 4)] + movups xmm1, XMMWORD [block + 8 * SIZEOF_WORD] ;B: w1 = 08 09 10 11 12 13 14 15 + and t, -DCTSIZE2 * SIZEOF_WORD ; t = &t_[0] + mov [t + save_frame], frame + pxor xmm4, xmm4 ;A: w4[i] = 0; + punpckldq xmm0, xmm1 ;A: w0 = xx 01 08 09 02 03 10 11 + pshuflw xmm0, xmm0, 11001001b ;A: w0 = 01 08 xx 09 02 03 10 11 + pinsrw xmm0, word [block + 16 * SIZEOF_WORD], 2 ;A: w0 = 01 08 16 09 02 03 10 11 + punpckhdq xmm3, xmm1 ;D: w3 = 04 05 12 13 06 07 14 15 + punpcklqdq xmm1, xmm3 ;B: w1 = 08 09 10 11 04 05 12 13 + pinsrw xmm0, word [block + 17 * SIZEOF_WORD], 7 ;A: w0 = 01 08 16 09 02 03 10 17 + ;A: (Row 0, offset 1) + pcmpgtw xmm4, xmm0 ;A: w4[i] = (w0[i] < 0 ?

Its reciprocal throughput (issue latency) is 1 even on +; modern CPUs, so chains of pinsrw instructions (even with different outputs) +; can limit performance. pinsrw is a VectorPath instruction on AMD K8 and +; requires 2 µops (with memory operand) on Intel. In either case, only one +; pinsrw instruction can be decoded per cycle (and nothing else if they are +; back-to-back), so out-of-order execution cannot be used to work around long +; pinsrw chains (though for Sandy Bridge and later, this may be less of a +; problem if the code runs from the µop cache.) +; +; We use tzcnt instead of bsf without checking for support. The instruction is +; executed as bsf on CPUs that don't support tzcnt (encoding is equivalent to +; rep bsf.) The destination (first) operand of bsf (and tzcnt on some CPUs) is +; an input dependency (although the behavior is not formally defined, Intel +; CPUs usually leave the destination unmodified if the source is zero.) This +; can prevent out-of-order execution, so we clear the destination before +; invoking tzcnt. +; +; Initial register allocation +; rax - buffer +; rbx - temp +; rcx - nbits +; rdx - block --> free_bits +;
