Full system emulation of approximate memory platforms with AppropinQuo
In this work we present an emulation framework for hardware platforms provided with approximate memory units, called AppropinQuo. The specific characteristic of AppropinQuo is to reveal the effects, on the hardware platform and on software, of errors introduced by approximate memory circuits and architectures. The emulator allows to execute software code without any modification with respect to the target physical board, since it includes the CPU, the memory hierarchy and the peripherals, capturing as well software-hardware interactions and faults due to approximate memory units.
