Insert the new element at one end of the vector, while simultaneously shifting all of the others one place closer to the output side. Put the code in a clocked process and tap the last bit in the vector, and you have your shift register. 1.

That means you need to count up to 25e6 (or (25e6)-1, depending how you set it up), reset the counter back to zero, and begin counting again. Every time your counter reaches 0 (or 25e6, or any other single value in the count), you can pulse an enable for one clock cycle.
