MAX.B
Maximum Value Packed Byte
MAX.BU
Maximum Value Packed Byte Unsigned
Description
Compute the maximum value of the corresponding bytes in D[a] and D[b] and put each result in the corresponding
byte of D[c]. The operands are treated as either signed (MAX.B) or unsigned (MAX.BU), 8-bit integers.
MAX.BD[c], D[a], D[b] (RR)
D[c][31:24] = (D[a][31:24] > D[b][31:24]) ? D[a][31:24] : D[b][31:24];
D[c][23:16] = (D[a][23:16] > D[b][23:16]) ? D[a][23:16] : D[b][23:16];
D[c][15:8] = (D[a][15:8] > D[b][15:8]) ? D[a][15:8] : D[b][15:8];
D[c][7:0] = (D[a][7:0] > D[b][7:0]) ? D[a][7:0] : D[b][7:0];
MAX.BUD[c], D[a], D[b] (RR)
D[c][31:24] = (D[a][31:24] > D[b][31:24]) ? D[a][31:24] : D[b][31:24]; // unsigned
D[c][23:16] = (D[a][23:16] > D[b][23:16]) ? D[a][23:16] : D[b][23:16]; // unsigned
D[c][15:8] = (D[a][15:8] > D[b][15:8]) ? D[a][15:8] : D[b][15:8]; // unsigned
D[c][7:0] = (D[a][7:0] > D[b][7:0]) ? D[a][7:0] : D[b][7:0]; // unsigned
