FPGA Reconfiguration using 2 processors.

[badfate]

Hello,

I've been working on the topic since 8 months and different types of reconfiguration using single soft core is done. I need some help on the procedure as well as theory about using 2 cores.

On the FPGA board that i use, there is PPC hardcore and microblaze softcore.

Not sure what you are asking. Are you asking about communication between the two cores (one in fpga and one external)? I'm not sure why you are referring to reconfiguration. I understand reconfiguration as loading a new fpga configuration. Are you doing this dynamically? Again, Your question is not clear.

 

[badfate]

Yes, its done dynamically(without resetting the system, you change a command on hyperterminal/ using a controlling switch on FPGA or give some delay so that the bit file hence functionality changes automatically).

I'm using soft core processor for writing the controlling code that monitors the bit file execution on FPGA. But there exists PPC hardcore on FPGA itself which i haven't used. I want to explore different methods of partial reconfiguration using both the processors.

I ll be glad if anyone can help me with even 2 soft cores if not PPC.

BTW, the board I'm using is Xilinx, virtex 5 s/w, 12.4

 

[meBigGuy]

I have never done any partial reconfiguration. Sorry

I want to use both of them for reconfiguration purposes.

Hello there,

I find your work on FPGA reconfiguration using a single soft core very interesting. Using multiple processors for reconfiguration can potentially enhance the speed and efficiency of the process. However, the procedure and theory for utilizing two cores may differ from using a single core.

One approach could be to divide the reconfiguration process into two parts and assign each core with a specific task. For example, one core can handle the data processing and the other can focus on the actual reconfiguration of the FPGA. This can potentially reduce the overall time required for reconfiguration.

In terms of theory, using multiple cores may require synchronization and communication between the two processors. This can be achieved through inter-processor communication protocols such as AXI or shared memory. Additionally, the choice of which core to use for a particular task may also depend on factors such as processor speed and available resources.

I suggest conducting further research on multi-core FPGA reconfiguration and exploring different approaches to utilizing two processors for this purpose. Good luck with your work!
