How to make Master module to access the avalon MM slave peripherals

[Altera_Forum]

Hi, 

 I am writing code for making the master module to access the avalon MM slave peripherals (e.g. UFM and ADC). But first I need to know that is there any IP available to access these modules (UFM and ADC)?? I dont want to use NIOS II processor as Master because I dont have enough memory. I am using MAX10SAU169C8GES FPGA. What could be the possible solutions??   Thanks in advance for the comments and suggestions.

What is your question actually?As I know every avalon-mm master component like JTAG master should be able to access both UFM and ADC.

Thanks for your reply... 

 Actually, I have a microcontroller which sends commands to my FPGA. There is different images I need to store in UFM of FPGA and with every command (from uC) I need to show the respective image on the screen. This is the rough structure. Since UFM is slave connected to Avalon MM fabric and I want to make controlling module which behave as Master. What should I do?? You are saying JTAG master can access the UFM. Can I use it to do my task??? But with the JTAG master do I need to use USB blaster. I am confused with that. It would be nice if you suggest suitable solution. If you dont understand I can explain it in more detail.

Yes, USB blaster is needed if using JTAG interface. You did not specify what kind of interface using for the data transfer from the microcontroller. I suggest you can study and apply the concept of SPI Slave to AvalonMaster Bridge in here chapter 18 https://www.altera.com/en_us/pdfs/literature/hb/nios2/qts_qii55004.pdf.
