Interfacing microblaze processor to vhdl logic

Hi,

 

I want to interface microblaze processor (on which data acquisition through ethernet is beng carried out)  to my vhdl logic. I'm not sure how to do this. 

 

Any help on this issue will be appreciated.

 

Just for reference, I'm using ethernetlite and have attached my system.mhs file, if any change in hardware is needed.

 

Regards,

 

mayankara

Re: Interfacing microblaze processor to vhdl logic

You can make your VHDL logic into a custom IP and interface it with microblaze processor.

check chapter 6 of EDK CTT:

Re: Interfacing microblaze processor to vhdl logic

Hi sampat,

 

I have added AXI-4 Stream FIFO bus interface in my vhdl logic for high throughput. I have not yet made it as a custom IP. If I'm making it as a custom IP and exporting it to EDK, do I need to write a device driver for AXI-4 Stream in application side?

 

Regards,

 

mayankara
