Rejection Sampling in NEON
make to build all make bench to start benchmarking cycles count. Please read papi_hl_output to see the result. The PAPI_TOT_CYC field describe the total clock cycles over a number of TESTS iteration. make verify to verify the vectorize implementation compare with reference code. This code is developed and tested on Raspberry Pi 4 8Gb Cortex-A72.
