14966 | 改进的CORDIC算法在资源消耗、输出时延方面优于传统CORDIC算法,适用于高精度计算的场景。 | The improved CORDIC algorithm is superior to the traditional CORDIC algorithm in terms of resource consumption and output delay, and is suitable for high-precision computing applications. |
14967 | 传统的排序方法主要以软件串行的方式实现,包括冒泡排序、选择排序等。 | Traditional sorting methods are mainly implemented in software serial mode,including bubble sorting,selective sorting and so on. |
14968 | 这些算法往往采用顺序比较,运算的时间复杂度较高。 | These algorithms often use sequential comparison,and the operation time complexity is relatively high. |
14969 | 近年来已经提出了一些并行度较高的排序算法,但是由于CPU的硬件特点,不能很好地利用这些算法的并行性。 | In recent years, some sorting algorithms with a high degree of parallelism have been proposed, but due to the hardware characteristics of the CPU,the parallelism of these algorithms cannot be used well. |
14970 | 而FPGA具有良好的灵活性、并行性和集成性等特点,因此在FPGA上可以更好地发挥这些并行算法的优势,从而大大提高数据排序的实时性。 | And FPGA has the characteristics of good flexibility, parallelism and integration,so the advantages of these parallel algorithms can be better utilized on FPGA,thereby greatly improving the real-time performance of data sorting. |

14972 | 结果显示,该系统对于并行性高的排序算法具有良好的加速效果,但逻辑资源消耗巨大,适用于实时性要求高的算法加速场景。 | The results show that the system has a good acceleration effect for sorting algorithms with high parallelism,but consumes huge logic resources,and is suitable for algorithm acceleration scenarios with high real-time requirements. |
14973 | 通用地球系统模式(Community Earth System Model,CESM)是一种定量描述气候系统模式变化的数值模式,庞大的科学计算体量已使其成为高性能计算领域的重要研究对象之一。 | The Community Earth System Model(CESM) is a numerical model to quantitatively describe the change of climate system model,which is one of the most important research objects in the field of high-performance computing because of its huge volume of scientific computing. |
14974 | CESM各个气象子模块及组件之间的负载不均衡问题使其计算性能一直不理想,且由于其可用的进程布局方案本身的多样性会导致的巨大检索量,因此通过人工调参用枚举寻找最优布局本身并不现实。 | The load imbalance between each meteorological sub module and component of CESM makes its computing performance unsatisfactory.It is not realistic to retrieve the optimal layout manually by enumerating parameters because the diversity of available process layout schemes will lead to a huge amount of retrieval. |
