Okay. Will check IACA report and try pxor for m0 and buffer 1023.

'psignb X, [pb_128]' equal to 'psubb X, 0, X', in AVX2, second type
faster, in SSE4, choice depends on IACA report
in PMINSW, you buffer ZERO

in PMINSW, you buffer ZERO into M0, and use pw_1023 directly, could you try
buffer pw_1023 and use PXOR to get ZERO?
