Hello,

your question addresses three aspects:

1. FPGA internal memory. It can generally be used up to the existing capacity wit each device. Accessing internal memory is faster and easier to achieve than any external memory.

2. Storing data to memory. Data can either be "stored" to memory at compile time, this would be a ROM function, using hex or mif files. Or data can be stored to memory at run time. This obviously requires an interface to transport the date.

3. Interfacing memory. FPGA internal memory can be accessed conveniently through Quartus "In-System Memory Editor" using the JTAG interface. Or through any interface mechanism realized in your code, using any existing interface, e. g. JTAG, Ethernet, RS232, custom parallel port.

Regards,

Frank
