为降低实现高阶矩阵SVD时的硬件复杂度和计算延时
本文改进了CORDIC迭代结构
设计了一种用于SVD的低硬件复杂度、高速CORDIC计算单元.本文以22矩阵为例
基于XilinxVirtex6硬件平台设计并实现了使用优化后CORDIC计算单元的SVD模块
在19bit位宽下吞吐率达25.9Gbps.对比Xilinx IP core中同类模块
本文设计节省27.6%寄存器
27.7%查找表
实时性提高14%.对高阶矩阵
本文给出资源消耗趋势曲线
可证明优化后CORDIC计算单元能降低16阶矩阵SVD模块约40%的硬件复杂度.
In order to reduce the hardware complexity and the delay of high-order SVD processor
two improved CORDIC modules including Arc Tan and Rotation functions are designed.These two improved CORDIC modules have better performance in terms of register saving and real-time quality.In this paper
a 22SVD module using above-mentioned CORDIC modules with 19bit data width has implemented on XilinxVirtex6 and the throughout reaches 25.9Gbps.Compared with the 2x2SVD module using IP core
it reduced 27.6% registers
27.7% LUTs and improved 14% real-time performance.Moreover
the trend curves of hardware consumption are presented which have testified that these two improved CORDIC modules can reduce 40% hardware complexity of 16-order SVD processor.
