An emulator for approximate memory platforms based on QEmu
In this paper, an emulation environment for approximate memory architectures is presented. In the context of error tolerant applications, in which energy is saved at the expense of the occurrence of errors in data processing, approximate memories play a relevant part. Approximate memories are memories where read/write errors are allowed with controlled probability. In general these errors are the result of circuital or architectural techniques (i.e. voltage scaling, refresh rate reduction) introduced to save energy.
