摘要

现代处理器和内存的性能差距很大，导致内存墙现象，导致系统整体性能下降。最近，PIM作为克服内存墙现象和提高系统性能的解决方案之一出现了。本文研究了如何在PIM逻辑中实现一些广泛应用的功能。我们的实验是基于gem5模拟器。实验结果表明，PIM的一些函数效率更高，其效率取决于数据的大小。

PIM architecture exploration for HMC

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.
