LT.H
Less Than Packed Half-word
LT.HU
Less Than Packed Half-word Unsigned
Description
Compare each half-word of data register D[a] with the corresponding half-word of D[b]. In each case, if the value
of the half-word in D[a] is less than the value of the corresponding half-word in D[b], set all bits of the corresponding
half-word of D[c] to one; otherwise clear all the bits. Operands are treated as signed (LT.H) or unsigned (LT.HU)
16-bit integers.
LT.HD[c], D[a], D[b] (RR)
D[c][31:16] = (D[a][31:16] < D[b][31:16]) ? 16’hFFFF : 16’h0000;
D[c][15:0] = (D[a][15:0] < D[b][15:0]) ? 16’hFFFF : 16’h0000;
LT.HUD[c], D[a], D[b] (RR)
D[c][31:16] = (D[a][31:16] < D[b][31:16]) ? 16’hFFFF : 16’h0000; // unsigned
D[c][15:0] = (D[a][15:0] < D[b][15:0]) ? 16’hFFFF : 16’h0000; // unsigned
