- NIOS does not support 32 bit address space, only 31 bits. The slave interface needs to cut down by at least one bit...likely more since if you have a 31 bit slave device connected to the NIOS, then it will consume the entire address space, leaving no address space for anything else...such as memory to read the software program.

- Does the slave interface of 'CDMA_ENCODING' really have 2^32 addressable memory locations? That's an awful lot. How many registers/ports are really addressable? That will define how many bits wide the address bus needs to be.

my custom logic does not store any thing,it does not have any registers . what ever the input it gets, it just encodes and gives out put. the ports are
before encoding: address:8-bit
data:32 bit
after endoding address : 4bit
data 16bit
after decoding address:8bit
data:32bit
how to know that address range?
thanks.
