Embedded Benchmark Suite

MiBech: free, commercially representative, source in C• Automotive & Industrial Control – basicmath, bitcount • Consumer devices – lame (MP3 encoder)• Telecommunication – FFT (digital signal processing), ADPCM

(Adaptive Differential Pulse Code Modulation, 16-bit into 4-bit)• Security – SHA (secure hash algorithm) for secure exchange

In the future – any code used for operating the wheelchairs
