// 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.

-// Macros
-
-// Set HOST_DEBUG to 1 if you are going to compile this for a host
-// machine (ie Athena/Linux) for debug purposes and set HOST_DEBUG
-// to 0 if you are compiling with the smips-gcc toolchain.

-// Set PREALLOCATE to 1 if you want to preallocate the benchmark
-// function before starting stats. If you have instruction/data
-// caches and you don't want to count the overhead of misses, then
-// you will need to use preallocation.
