Abstract
This article presents DynaPlasia, a reconfigurable eDRAM-based in-memory computing (IMC) processor with a novel triple-mode cell. It enables higher system-level performance and efficiency in a resource-limited environment. DynaPlasia proposes five key features that can enhance the energy effi- ciency and area efficiency of the IMC accelerator: 1) dynamic reconfigurable core architecture (DRECA), which dynamically reconfigures the effective IMC macro size according to DNN workloads; 2) the triple
