Modern processor and memory have significant performance gap that incurs memory-wall phenomenon causing overall system performance degradation. Recently, PIM came out as one of solutions to overcome memory-wall phenomenon as well as increasing system performance. This paper studies how to implement functions within PIM logic for some broadly used applications. Our experiments are based on gem5 simulator. The experimental results show that some of functions are more efficient with PIM and their efficiency depends on the data size.
