+RX System emulator
+--------------------
+
+Use the executable ``qemu-system-rx`` to simulate RX target (GDB simulator).
+This target emulated following devices.
+
+- R5F562N8 MCU
+
+ - On-chip memory (ROM 512KB, RAM 96KB)
+ - Interrupt Control Unit (ICUa)
+ - 8Bit Timer x 1CH (TMR0,1)
+ - Compare Match Timer x 2CH (CMT0,1)
+ - Serial Communication Interface x 1CH (SCI0)
+
+- External memory 16MByte
+
+Example of ``qemu-system-rx`` usage for RX is shown below:
+
+Download ``<u-boot_image_file>`` from
+https://osdn.net/users/ysato/pf/qemu/dl/u-boot.bin.gz
+
+Start emulation of rx-virt::
+ qemu-system-rx -M gdbsim-r5f562n8 -bios <u-boot_image_file>
+
+Download ``kernel_image_file`` from
+https://osdn.net/users/ysato/pf/qemu/dl/zImage
+
+Download ``device_tree_blob`` from
+https://osdn.net/users/ysato/pf/qemu/dl/rx-virt.dtb
+
+Start emulation of rx-virt::
