Can the DDR memory attached to the FPGA be directly mapped into system (CPU) memory space such that it can be used by the CPU like any other piece of system memory?
We tend to use the DDR memory as a private resource for FPGA use only. That is not to say that you could modify the application to allow this, but we have specifically not done because the DDR memory will be slower than access to CPU memory and this could kill application performance (The OS is free to use that memory to run any application). That being said, we do not have plans to implement cache-coherency. If this is a necessity for you and your program, you would need to obtain a license directly from AMD.
