In this paper, we present a technique to maximize the lifetime of SRAM-based FPGAs in space mission. We focus on recovering permanent faults induced by SEE (single-events effect). In our technique, we use a fix-sized fault detection module to detect permanent faults and propose a permanent fault recovery mechanism for fault recovery. By using partial reconfiguration, we develop a system lifetime estimation model to find the optimal partition for designing the module-based fault recovering with the maximum system lifetime. We conduct experiments with a set of real applications including SpaceWire, Wavelet, AC97, MEPG-4, 8086, and Ethernet on Xilinx XUP platforms. The experimental results show our technique can effectively improve the lifetime compared with the previous work.

Artificial reverberator is now widely used in broadcasting station, television station, singing and dancing hall, etc. It plays an important role in beautifying music, sugaring singing, glorifying phonetic timbre and the artistic re-creation. It can also produce many kinds of special acoustics. However, artificial reverberator is a very complex system related with many important items especially its time-delay and feedback. And it is hard for designers to find the parameter of these items accurately. Simulink is perfect tool to design the artificial reverberator and set the optimal parameter through simulation, which can result in better acoustics. In this paper, the design of artificial reverberator based on Simulink is introduced in detail. Also, a realistic simulation package is presented on the base of the discussion of the interface between Simulink and GUI. Experimental results show that the acoustics of artificial reverberation are much more natural than before.
