| 摘要: |
| 在简要介绍多普勒波束锐化(DBS)成像原理和TMS320C6201芯片特点的基础上，着重讨论了DBS成像算法基于DSP的实现。在实现过程中充分考虑了通用DSP完成非线性运算、除法运算耗时大以及存贮I/O操作耗时不能忽略等特点。最后分析了算法性能并给出了实验结果。 |

| Abstract: |
| This paper presents the principle of doppler beam sharpening(DBS) imaging and the characteristic of TMS320C6201. Then, the implementation of DBS imaging algorithm based on general DSP is described in detail, in which the characteristic of general DSP and the effect of memory I/O operation are taken into account. In the end the performances are analyzed and experiment results presented. |
