Sharing memory between PowerPC and Custom IP

Hello,

 

I am currently working on ISE 13.2 and development board ML 510.

 

I have a C program that writes some data into a piece of memory, and a custom IP will operate all that pieces of data and write result back to the memory. I am wondering if there are any examples that I can look at ?

 

Thank you very much for any help.

Re: Sharing memory between PowerPC and Custom IP

I am attaching my hardware design from ISE here. In this simple example, I have a very simple custom IP "dividedby2". My goal is to have the C program running on PowerPC writing data to a range of memory, and have the "dividedby2" IP access that said memory location and perform operations on the data, and write the result back to another memory location.

 

Is the hardware design suffice to do what I need. Or do I need to create another memory controller so I can attach it to Port B of the bram ?

 

Thank you very much for any help.

Re: Sharing memory between PowerPC and Custom IP

Hello @normanlo,

 

We are looking into this issue for you. Currently most of the ML510 links to reference designs are bad, so I have reported that to the Xilinx Web Team. I will let you know when the links get fixed so we can start there.

 

Thanks,
Cory
