Description
Performs a bitwise XNOR between the vector mask k2 and the vector mask k3, and writes the result into vector mask k1 (three-operand form).
Operation
KXNORW
DEST[15:0] <- NOT (SRC1[15:0] BITWISE XOR SRC2[15:0]) DEST[MAX_KL-1:16] <- 0
KXNORB
DEST[7:0] <- NOT (SRC1[7:0] BITWISE XOR SRC2[7:0]) DEST[MAX_KL-1:8] <- 0
KXNORQ
DEST[63:0] <- NOT (SRC1[63:0] BITWISE XOR SRC2[63:0]) DEST[MAX_KL-1:64] <- 0
KXNORD
DEST[31:0] <- NOT (SRC1[31:0] BITWISE XOR SRC2[31:0]) DEST[MAX_KL-1:32] <- 0
