shift left/shift right in VHDL
 

Dear

Question: how to shift left or shift right

Rough program as follows

library IEEE
...
...

Package matrix_types Is
Type matrix_4x1 Is Array (1 to 4) Of std_logic_vector (7 downto 0);
Type matrix_1x4 Is Array (1 to 4) Of std_logic_vector (7 downto 0);
Type matrix_4x4 Is Array (1 to 4, 1 to 4) Of std_logic_vector (7 downto
0);
End Package matrix_types ;
...
...
architecture.......
begin
.....
process
.......

Variable x : matrix_4x1 :=
("000000100",
"0000000000",
"0011110000",
"0010110001");

begin

QUERY: Now i have to shift left or shift right EACH ROW of variable x either TWICE or
THRICE etc.

Please reply me dear...

Thanks and Best Regards,
