Using an array as an input buffer

[dannybrowne]

Hi all,

I am new to VHDL and am trying to implement a buffer which takes std_logic inputs and puts them into a std_logic_array (my buffer) before output. I don't know how to put a series of bit values into an array and make them shift along to output.

I need to keep these values in array as I will need to read the contents of the array at different stages.

I would be very greatful of any help as im worried this might just ruin christmass for me!

Cheers danny

Are you trying to convert to a different data type as well? or will your array still be std_logic?

if it's still std_logic, use std_logic_vector. Vectors can be indexed just like an array but are more akin to data buses.

If you're going to change the data type to something other that std_logic, you'll have to convert the input data type befor assigning it to an array element.
