I want to know the difference betwn Avalon MM Data Master Port and Avalon MM Instruction Master Port. Which out of these should be connected to Onchip Memory, JTAG UART, custom block, performance counter and WHY ??? --- Quote End --- The instruction master is used for fetching instructions. The data master is used for performing data operations (reading/writing variables your program uses, reading/writing peripheral control registers). Connect the instruction master to the memory where your program is located. Connect the data master to (basically) everything including the program memory.
