Hi, i want to know what might be the best possible way of reading and writing to memory. I want to be able to initially store some data in RAM and then have a component designed in VHDL retrieve data from RAM and then store the result after manipulating the data back in RAM.
What i could think of is to design a system in SOPC with Nios II/e core, JTAG and some onchip RAM. Now how can i add data into RAM(maybe through a HEX file) and then retrieve it and pass it on the component. I could write a C application that would transfer from one memory location to another. But should there be an output port from the SOPC system module or a new avalon interface defined? I am not if there is a difference?
This system should be standalone as the component could continously read RAM and once flagged(by reading flag bit) retrieve data from RAM and store the result in a specified location in RAM.
Could someone please guide me on what to do i would really appreciate your help.
Thanks
