+description: |
+  The FastRPC implements an IPC (Inter-Processor Communication)
+  mechanism that allows for clients to transparently make remote method
+  invocations across DSP and APPS boundaries. This enables developers
+  to offload tasks to the DSP and free up the application processor for
+  other tasks.
