Title
DP-Sim: A Full-stack Simulation Infrastructure for Digital Processing In-Memory Architectures
Abstract
ABSTRACTDigital processing in-memory (DPIM) is a promising technology that significantly reduces data movements while providing high parallelism. In this work, we design and implement the first full-stack DPIM simulation infrastructure, DP-Sim, which evaluates a comprehensive range of DPIM-specific design space concerning both software and hardware. DP-Sim provides a C++ library to enable DPIM acceleration in general programs while supporting several aspects of software-level exploration by a convenient interface. The DP-Sim software front-end generates specialized instructions that can be processed by a hardware simulator based on a new DPIM-enabled architecture model which is 10.3% faster than conventional memory simulation models. We use DP-Sim to explore the DPIM-specific design space of acceleration for various emerging applications. Our experiments show that bank-level control is 11.3x faster than conventional channel-level control because of higher computing parallelism. Furthermore, cost-aware memory allocation can provide at least 2.2x speedup vs. heuristic methods, showing the importance of data layout in DPIM acceleration.
