中文摘要: 针对高精度高分辨率数控振荡器(NCO)存储器消耗巨大资源的问题,提出了利用奇偶对称性的存储内容映射技术,基于地址内容模拟曲线技术和基于存储内容的分段差分技术;通过存储内容和地址的数学模型从理论上推导了利用奇偶对称性的存储内容映射技术和基于地址内容模拟曲线技术的性能;对基于存储内容的分段差分技术进行了定性分析和实例仿真。这3种技术均能较好地减少存储资源,将其组合起来应用,其存储资源能减少到3%以下。
Abstract:The Map Technology of Storage Contents in accordance with even and odd symmetry, the Curve Fitting Technology based on address contents and the Division Difference Technology based on storage contents were used to solve the problem that storage resources is heavily demanded in high precision and high resolution NCO storage. The performance of the Map Technology of storage contents in accordance with even and odd symmetry, and the Curve Fitting Technology based address contents were derived by the mathematical model of content and address. The Division Difference Technology based on storage contents was analyzed qualitatively and simulated with an instance. All the three methods can efficiently reduce resources,which can be reduced to less than three percent by the simultaneous use of two or three efficient technologies.
