AXI4 streaming with Microblaze and FIR filter

Hello,

I am trying to interface FIR filter S_AXIS_RELOAD and S_AXIS_CONFIG ports with Microblaze AXI4 stream. Pls. find attached herewith for my design diagram (vivado 2016.2).  I am confusing about how can I transfer data from microblaze to FIR filter? 

 

I noticed that AXI4-streaming is FSL communication, and I have to use putfsl(val, id) (mb_interface.h) for the microblaze. I am confusing about device ID in putfsl. I dont see any parameters in xparameters.h, or I am missing. 

 

I would be glad if you provide any example mb C-code in this regards. 

 

Thanks for your kind help. 

 

Thanks
