Questions tagged [sll]

sll stands for "shift left logical", an operation on a bit vector in VHDL. Use this tag for questions about this operation in the context of VHDL programming

Performs a logical (filled with zeros on the right) shift left of a vector in VHDL.

Use Model:

signal a_reg : std_logic_vector(31 downto 0);

a_reg <= "10101010101010101010101010101010";

a_reg <= a_reg sll 3;

This will shift a_reg left by three and the new value will be:

01010101010101010101010101010000

MIPS Assembly sll instruction

I have a problem with the sll instruction. sll $t1,$a0,1 with $a0 holds the value 11 would give $t1 the value 16 (I tested it in MARS). My suggestion for $t1 was 22, becaus a left shift of 11 aka 01011 would give me 10110, what is 22 in decimal.…
