/*
 *  General:
 *  Input interfaces provide inputs to functions inside test templates.  They
 *  ONLY provide the inputs.  The output variables should be hard coded.
 *
 *  The input interfaces must have the following format:
 *
 *  ARM_xxx_INPUT_INTERFACE() or
 *  REF_xxx_INPUT_INTERFACE()
 *
 *  The xxx must be lowercase, and is intended to be the indentifying substring
 *  in the function's name.  Acceptable values are 'sub' or 'add' from the
 *  functions arm_add_q31.
