+# DBus Application with NPU-DDK
+
+This page describes how to prepare DBus-compatible environment in the FastModel simulator,
+and how to run our test program using DBus.
+
+## Setting up DBus
+
+First of all, you should install `dbus` package in the FastModel.
+
+```console
+$ telnet localhost 5000
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.
+...
+sh-3.2# zypper install dbus
+...
+```
+
+Also, make sure that DBus's runtime directory exists. If don't, just create it.
+```console
+sh-3.2# ls /run/dbus
+cannot access /run/dbus: No such file or directory
+sh-3.2# mkdir -p /run/dbus
+```
+
+Then, you can start the dbus daemon. We recommend to append this to your `/init` script.
+```console
+sh-3.2# /usr/bin/dbus-daemon --system --nopidfile --syslog-only
+sh-3.2# ls /run/dbus
+pid  system_bus_socket
+```
+
+## Starting DBus Service 
+
+We provide sample DBus application which emulates VD NPU Manager. Note that it's not real one
+and just uses the provided interface only.
+```console
+sh-3.2# zypper install npu-engine-example
+...
+sh-3.2# ls /usr/share/dbus-1/system.d/
+sr.odl.NPUManager.conf
+sh-3.2# /usr/bin/dbus-daemon --system --nopidfile --syslog-only
+sh-3.2# /usr/lib64/npu-engine/bin/apptests/npumgr/dummy_npumgr
+sh-3.2# /usr/lib64/npu-engine/bin/apptests/npumgr/apptest_npumgr \
+        /usr/share/npu-engine/testdata/TRIV235_2TOPS/MOBILENET_V1
+[   25.222285] triv2 30410000.triv2: Execution Cycles: 114545
+[APPTEST] /usr/lib64/npu-engine/bin/apptests/npumgr/apptest_npumgr: PASSED
+```
+
+## Additional Notes
+
+Because our FastModel simulator only supports a single host CPU core, a multi-thread daemon such as DBus may make the overall system slow down.
+So, please terminate the DBus daemon when you don't use it anymore.
