Ok my cuestion is, I have one project created with the processor NIOS II standard, may i implement inside the same project an accumulator to asign data from the PIOs of the processor in less how i can insert a symbol (accumulator) in the same project NIOS II. :(:(:(

thats many ways to do that........... when i saw you can read pios and store to a onchip this is sof solution.... 

 

or you can do it in hardware..... do a vhdl acumulator and read by avalon mm

add to your vhdl block a spi interface to communicate to fpga...... and at sopc add a MM to read data from this block
