+# 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 `` library) compiled
for execution on Hexagon.
+The prerequisite is to have Hexagon SDK installed, preferably version 3.5.0 or later. The
Hexagon SDK can be downloaded from
+### Compiling TVM runtime for x86
+This will use Hexagon simulator, which is provided in the Hexagon SDK.
+When configuring TVM (cmake), set the following variables:
+Set the C/C++ compiler to `clang`, and pass `-DCMAKE_CXX_FLAGS='-stdlib=libc++'` to the cmake
 Review comment:
   Does it a must? I use g++ and libstdc++ ever and no problem.
