...The benchmarks that have been chosen: - CRC32, SHA - Prime sifting - Integer / floating point matrix multiplication - Cubic root solver - 2D convolution, FFT, fast discrete cosine transform - Dijkstra, Patricia - Rjindael, Blowfish, Triple DES - Arithmetic coding (?) More info at: http://jpallister.com/wiki/index.php?title=Benchmarks#Final_Benchmark_Choice These have been chosen because: - most have code available under the GPL - they are small enough to fit on the target platforms (the ARM Cortex-M0 we have only has 64 KiB flash and 8 KiB RAM) - they are wide ranging enough to exercise...

...has on the energy consumption of different embedded platforms. To do this we are finding a set of relevant benchmarks, compiling them with different options and measuring their energy consumption on these platforms. We originally announce this project at the GCC Cauldron (presentation here http://jpallister.com/wiki/images/4/44/Gcc-cauldron-low-power-9-jul-12.pdf). Questions we'd like to answer: - Which set of benchmarks are suitable for embedded applications and representative of possible applications? - What compiler options have the most effect on the power consumption of the device? - Do...
