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.
