Hi everybody,
I implement an xps system by using the Bus PLB. My IP core is added to the system using Create or Import Peripheral...
The Microblaze write several data to DDR2 SDRAM. I want to know how the IP core read all the data from this memory, modify it and write it back to DDR2 SDRAM via the PLB Bus interface.
Therefore, I would like to write the image data directly to DDR SDRAM. However, I am not sure how I can get my custom core to read/write data from/to the DDR using the PLB bus.
If anyone could point me in the right direction, I would really appreciate it. I know that I will need to make my custom core a "Master" on the PLB bus but I can't find a good example on how to read/write to memory.
Thanks in advance.
