README

          
This is a simple memory benchmark program, which tries to measure the peak

bandwidth of sequential memory accesses and the latency of random memory

accesses. Bandwidth is measured by running different assembly code for

the aligned memory blocks and attempting different prefetch strategies.

The benchmark results for some hardware can be found in the wiki page:

    https://github.com/ssvb/tinymembench/wiki

This program can be compiled in either linux or windows (via mingw32 and msys)

by simply running make:

    $ make

Adding extra optimization options is possible (in linux):

    $ CFLAGS="-O2 -march=atom -mtune=atom" make

Example of crosscompiling for ARM (also in linux):

    $ CC=arm-linux-gnueabihf-gcc CFLAGS="-O2 -mcpu=cortex-a9" make

Example of crosscompiling and running the benchmark on android device:

    $ CC=arm-linux-gnueabihf-gcc CFLAGS="-O2 -mcpu=cortex-a8 -static" make

    $ adb push tinymembench /data/local/tmp/tinymembench

    $ adb shell /data/local/tmp/tinymembench
