摘要

提出了一种SVD处理器系统,其中每个处理元素都使用一个简单的CORDIC单元实现。利用CORDIC模块内部的递归循环,使用流水线将两个独立的微旋转复用到单个CORDIC处理器上。这导致了高性能和高效的硬件架构。此外,还提出了一种新的尺度因子校正方法,该方法只需在计算结束时进行一次校正。这也减少了计算时间。最终的结果是基于传统CORDIC方法的SVD架构,它结合了高性能和高硅面积效率。

A floating-point CORDIC based SVD processor
An SVD processor system is presented in which each processing element is implemented using a simple CORDIC unit. The internal recursive loop within the CORDIC module is exploited, with pipelining being used to multiplex the two independent microrotations onto a single CORDIC processor. This leads to a high performance and efficient hardware architecture. In addition, a novel method for scale factor correction is presented which only need be applied once at the end of the computation. This also reduces the computation time. The net result is an SVD architecture based on a conventional CORDIC approach, which combines high performance with high silicon area efficiency.
