storing ADC data to SDRAM

Hello. 

First of all, I am really sorry about my poor english and grammer that irritates you. 

 

I'm going to make my own system which's gathering 14-bit analog signal through ADC and Storing them to SDRAM, or SRAM, etc... 

So, I made custom IP to gather ADC data from HSMC connection through Couduit_end port and avalon_slave to nios_ii system. 

I stored instruction data to on-chip memory and empty SDRAM. 

 

avalon_slave has 6 ports that outs 32 bit as a readdata, and as input port 2-bits of address, 4-bits of byteenable, and write, 32-bit writedata, and read signal. 

 

my system environment is like this. 

DE2-115,EP4CE115F29C7N 

DCC-terasic data_conversion_card with hsmc connection 

 

Should I change plan to make Avalon-ST system or using DMA to accomplish my goal? 

Or, Do I have to study eclipse to control memory? 

 

I'll attatch my V-file, so please help me to get through this stuffed problem. 

 

Again, really sorry about my poor english.
