// Median filter bencmark

//
// This benchmark performs a 1D three element median filter. The
// input data (and reference data) should be generated using the
// median_gendata.pl perl script and dumped to a file named
// dataset1.h You should not change anything except the
// HOST_DEBUG and PREALLOCATE macros for your timing run.

// Main

int main( int argc, char* argv[] )
{
  int results_data[DATA_SIZE];

  // Output the input array
  printArray( "input",  DATA_SIZE, input_data  );
  printArray( "verify", DATA_SIZE, verify_data );

#if PREALLOCATE
  // If needed we preallocate everything in the caches
  median( DATA_SIZE, input_data, results_data );

  // Do the filter
