sub-function怎么读

demands of aftermarket parts' collaborative system are analyzed as a sub-function configured on the platform alone.

售后配件协同系统作为配置在此平台上的一个子功能单独出来进行了配件协同管理系统的需求分析，在需求部分给出了售后配件管理系统分模块业务协作示意图及用例模型。

Then through the CCS to debug DSP software development testing, sub-function to calculate the time occupied by image processing. Finally, the future of the system and the image processing system based on DSP development of summary and outlook.

然后通过DSP开发软件CCS进行调试测试，再分函数计算程序运行所占用的时间。最后，对本系统以及今后基于DSP的图像处理系统的发展作了总结与展望。

Thirdly, according to the actual transport needs of Solid State Disk, we focused on the use of FPGA to achieve the ATA protocol, and introduce the logic realization and process of the general framework and specific sub-function modules.

然后，论文结合固态硬盘的实际传输需求，重点研究了用FPGA来实现ATA协议的方法，并详细介绍了FPGA内部的总体功能框架及各个子功能模块的逻辑实现方法和流程。
