is there a way to buffer a continuous string of integers with out using a buffer. i am using a MATLAB function block to store integers in a vector and then outputting the vector to the input of a reed-solomon encoder. however i can not seem to get it to work. the next question i have is: is it possible to use a reed-solomon in sample mode as apposed to frame mode. this is all to by-pass the VHDL code generating limitations associated with frame-based modeling.
thanks srussell22

Try to use a Mux block to buffer and Demux block to unbuffer

If you are targeting VHDL via HDL Coder you will need some form of storage for your data; it has to be kept somewhere. The simplest to implement might be an Integer Delay block of the appropriate length. A second is to use a HDL FIFO, which will give you more control than the simple Delay block. Another option is to design using a RAM block to store your data. A fourth option, depending on your hardware setup, is to store the data in an external RAM (not part of your HDL design) and feed the data sequentially into your encoder.
