Matrix Vector

[petetepeke]

Hi.
I want to assign the first row of a matrix to a vector of the same type.How can i do it?
....
TYPE matrix is array (integer range<>,integer range<>) of integer
TYPE vector is array (integer range<>) of integer;
....
a: matrix(0 TO 10,0 TO 10);
b: vector(0 TO 10);
....
--I've considered this instruction but compile error
vector <= a(0,0 TO 10);

How can i do that???I need that to make GENERATE instruction to multiply these....THANKS

You could just use generate to that to. simply a for-generate loop would do that. (I hope I have understood what your problem is.)

well first of all

vector <=a(0,0 TO 10)

won't work, as vector is a type, not a signal in your design. Try

b <= a(0,0 TO 10)

yeah, and you are probably wanting a for-generate loops.. something like

for i in 0 to 10 generate
b(i) <= a(0,i);
end generate;

That should work. I personally feel more comfortable using bit vectors then integers. The way you are declaring your integers you could be taking up a LOT of space on your chip.
