The formulations of mean time to failure and reliability under multiple factors are deduced of the soft errors of space memory systems affected by SEU（single event upsets）. A quickly-to-calculate approximate formulas for mean time to failure of memories is produced. The optimal cost function which satisfied the system reliability is obtained by analyzed of the effect of the mean time to failure from four aspects : scrubbing interval, memory size, codeword length and error correction capability of ECC（error correct codes）. The results show that the memory reliability will be improved by reduced the scrubbing interval and increased the error correction capability of the ECC. The memory reliability will be changed by used of the ECC of different codeword length, even though the ECC has the same correction capability. All above of the elements of the cost function will be considered to reach the system reliability. The results of this paper can be used to design other space memory systems.

关键词： Mean time to failure (MTTF). Reliability. Error detection and correction (EDAC). Single event upsets (SEUs).

为了改进软件接收机的实时性，提出了一种新的并行相关器设计，不再采取常用的查找表方法，而是利用基于位操作的并行算法，以及处理器的SIMD（单指令多数据）指令集，分别对相关器中的乘法与求和运算进行了优化。新方法可适应各种信号量化位数，比现有算法性能提升4～10倍，在普通计算机上并行处理12通道的GPSL1频点信号时，处理器资源占用率不到1％。

Self-Organizing Approach for Finding Borders of DNA Coding R...

CCAST“复杂性问题”研讨会

作者： Fang Wu and wei-mou Zheng Institute of Theoretical Physics, Academia Sinica, Beijing 100080, China

＜正＞ Motivation: A good estimation of the borders of coding regions by a composition based algorithm will help signal-based algorithms to refine the annotation. The entropic segmentation approach has its limitations. A sell-organizing approach is proposed based on the model of codon usage for coding regions and positional preference for noncoding regions. Results: The symmetry between the direct together with reverse coding regions and phaseshifting are adopted for both reducing the number of parameters to as few as 63+3 and uniquely inferring noncoding regions and the 6 phases of coding regions. Without requiring prior training, parameters can be estimated by iteration. A multi-sampling technique from sliding windows is used to select segments with high confidence, which can provide a training set for other sophisticated algorithms. A mixed-window model is then used to find borders between the accurately inferred segments. Contact: zheng@***
