摘要
大规模集成电路近年的发展开辟了计算复杂的科学算法的硬件实现新领域,包括被称为坐标旋转数字算法(CORD IC)的一组移位和求和的算法。基于CORD IC算法的基础上,针对传统的旋转变压器解码算法中解码算法复杂、周期长的缺点,提出了一种旋转变压器解码全硬件算法实现的方案。利用移位寄存器和加法器实现解码算法,并且采用流水线技术,具有算法速度快和精度高的特点。使用所提出的新解码方案,以FPGA为平台搭建了旋转变压解码系统。试验结果证明了这种基于FPGA平台实现的旋转变压器解码系统具有高速及高精度的特点。
In this paper, a new method of resolver signal-processing algorithm is introduced which is a development of CORDIC algorithm. It overcomes the drawback of classical CORDIC algorithm which requires scale factor compensation is more suitable in the hardware implement. The new algorithm com pares with the software way Can reduce operation time. perimental result to indicate, the new methods design performance, especially the high speed characteristic, coding. Uses this algorithm build the decoding system exrotary transformer decoding system has the good can adapt under the high speed high accuracy decoding.
