Rejection Sampling in NEON

How to build

• Run make to build all
• Run 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.
• Run make verify to verify the vectorize implementation compare with reference code.

Test platform

This code is developed and tested on Raspberry Pi 4 8Gb Cortex-A72.
