I am using the Spartan-3 FPGA board. I require to send a series of inputs to the pipelined circuit implemented in the FPGA and correspondingly, get a series of outputs from the FPGA. I need to send the inputs from the computer to the FPGA at each clock cycle and get the outputs and store it in the computer memory. How do I do this?
thanks for your reply. can we use the jtag usb cable of the fpga to do this or do we need to use the serial port on the fpga board? also, is there some standard module that i can use to send inputs and receive outputs to and from the computer respectively?
U could connect the FPGA board to the PC using serial/RS-232 interface. U would have to implement a UART on ur FPGA. (Assuming ur FPGA board has a DB9 connector and a level translator on it) and interface the UART with ur pipelined circuitry.
After implementing UART u can communicate from the PC using Hyper Terminal or other such software if ur working on windows.
