Programmed-I/O-based data transfers might not only result in the wasting of valuable CPU cycles of microprocessors but also unnecessarily consume much more energy from batteries. This paper presents an interrupt-emulation mechanism for flash-memory storage systems with an energy-efficient management strategy. We propose to revise the waiting function in the Memory-Technology-Device (MTD) layer to relieve the microprocessor from busy waiting and to reduce the energy consumption of the system. We show that energy consumption could be significantly reduced with good saving on CPU cycles and minor delay on the average response time in the experiments. |
