DSP builder - loading and indexing a vector

Hi I'm using the DSP builder in Simulink (Matlab), where I am implemeting a split-radix FFT. I would like to load in a vector from my workspace and then adress each element in the vector as I ...

Hi - thank you for the quick answer

My problem is that I would like to load a vector generated in Matlab and then access it via the FPGA. I have managed to load the vector into simulink and store it in RAM, but I would really like to have a more "free" access to each element of the vector. My problem is that I have 4 different variabels which I use to index the vector with.

I have thought of a solution where I have a mux block which will choose which of the four variables index the RAM. Depending on which index variabel I use the output will have to be loaded to different adders. Therefore I will need a demux block after the RAM.

Unfortunately this solution will require a lot of control. Therefore I would like to know if it possible to get a register which I can access independently of the other registers?

-thanks
