LT.B
Less Than Packed Byte
LT.BU
Less Than Packed Byte Unsigned
Description
Compare each byte of data register D[a] with the corresponding byte of D[b]. In each case, if the value of the byte
in D[a] is less than the value of the byte in D[b], set all bits in the corresponding byte of D[c] to one; otherwise clear
all the bits. The operands are treated as signed (LT.B) or unsigned (LT.BU) 8-bit integers.
LT.BD[c], D[a], D[b] (RR)
D[c][31:24] = (D[a][31:24] < D[b][31:24]) ? 8’hFF : 8’h00;
D[c][23:16] = (D[a][23:16] < D[b][23:16]) ? 8’hFF : 8’h00;
D[c][15:8] = (D[a][15:8] < D[b][15:8]) ? 8’hFF : 8’h00;
D[c][7:0] = (D[a][7:0] < D[b][7:0]) ? 8’hFF : 8’h00;
LT.BUD[c], D[a], D[b] (RR)
D[c][31:24] = (D[a][31:24] < D[b][31:24]) ? 8’hFF : 8’h00; // unsigned
D[c][23:16] = (D[a][23:16] < D[b][23:16]) ? 8’hFF : 8’h00; // unsigned
D[c][15:8] = (D[a][15:8] < D[b][15:8]) ? 8’hFF : 8’h00; // unsigned
D[c][7:0] = (D[a][7:0] < D[b][7:0]) ? 8’hFF : 8’h00; // unsigned
