Create the onchip memory peripheral in SOPC Builder, and give it an appropriate name. Regenerate your system. In the IDE, regenerate your project&#39;s system library. Open the system.h file in there and somewhere in there is the base address of the memory peripheral.

For example, if I created an "On-chip memory (RAM or ROM)" device and named it "UART_cache", then regenerate SOPC, then regenerate system library, somewhere in the system library&#39;s system.h file will be a# define setting UART_CACHE_BASE to the base address of the on-chip memory. I don&#39;t remember if there is also a symbol generated for the memory&#39;s size.
