本文介绍一种基于CORDIC的协处理器结构,它能有效地进行关键的和先进的参数预算功能,其性能可与仙童9450(MIL-STD-1750A)处理器相比较。通过从系统主处理器分离出的关键性计算中包括的预算任务,并提供构造块以解决广泛范围的问题,同时增加一个数量级吞吐量的数字稳定矩阵宏观功能,这种协处理器大大增强了系统设计者的选择。在不影响其它关键系统功能的情况下,由于目前具有更多个状态和较高修正速率的更为逼真的模型是实际可用的,这样就导致了系统改善性能和提高精度。
This article presents a CORDIC based coprocessor architecture that effectively performs key and advanced parameter budget functions that compare with the Fairchild 9450 (MIL-STD-1750A) processor. The coprocessor greatly enhances the macro-functionality of the digital stabilization matrix by adding an order-of-magnitude throughput through budgetary tasks included in the key calculations that are separated from the system’s main processor and provides building blocks to solve a wide range of problems System designer’s choice. Without affecting the other critical system functions, the more realistic models with more states and higher correction rates are actually available, which results in improved performance and increased accuracy of the system.
