/**
 * @file Profile.h
 *
 * Very simple profiling macros.  Place PROF0(id) / PROF1(id, n) pairs
 * around the code you want to time.  The 'id' parameter must be a unique
 * identifier (valid C identifier) that will be used to label the test.
 * The 'n' parameter is the number of times to average before recording
 * the result to the log file.  Logging goes to the PROFILE target, so
 * you must enable this (--log=PROFILE on the CSPSim.py command line) to
 * see the timing results.  Each log entry contains the 'id' identifier
 * and the average execution time in milliseconds.
 *
