Since the new technologies like big data and cloud computing require tremendous amount of transactions between processors and memory, researches on a new memory system called Processing in Memory (PIM) architecture has been suggested as a solution for those memory intensive applications. To make software utilize the new architecture, a development environment with tool chain and debug infrastructures supplementing extended instruction sets and target emulation is needed. This paper introduces a way to emulate a target platform having PIM architecture memory device. The emulated platform may use the PIM device as a system memory or simple memory mapped bus device. The actual PIM architecture is implemented in both cycle-based memory simulator and FPGA based hardware platform. The emulator has a bridge for these implementations so the emulated target platform may be freely used with early stage application development for the PIM architecture.
