+# Hexagon backend runtime
+
+The Hexagon runtime is a part of the TVM runtime that facilitates communication between a
host and a Hexagon device. There are two types of host/device arrangements that are supported:
+- X86/Linux host running Hexagon simulator,
+- Android/AArch64 host running on a physical device containing a Hexagon module (i.e. CSDP
or ADSP).
+
+The TVM runtime that contains Hexagon runtime is the one executing on host.  In either case,
there will need to be a separate TVM runtime (i.e.  the `libtvm_runtime.so` library) compiled
for execution on Hexagon.
+
+The prerequisite is to have Hexagon SDK installed, preferably version 3.5.0.
 
 Review comment:
   While it might be hard to create an automatic installed version, we can look into at least
do the compilation tests, to make sure that the runtime compiles
