title: Map physical memory address to a user space application in windows
body: <p>Is it possible to map a physical memory address to a windows user-space application virtual address to read/write?</p>
  
  <p>EDIT:
  I have a system where a real-time operating system is running in parallel with windows. The guest-OS(RTOS) is able to read and write from/to a memory mapped PCIe slave peripheral by mapping the physical address to its virtual memory space.</p>
  
  <p>What i would like to do, is to be able to communicate directly with the PCIe slave device from a windows user space application, but this requires me to map that physical memory address to the user-space virtual memory-space.</p>
  
  <p>Thanks in advance.</p>
