在DSP技术教学过程中,片上外设往往得不到足够的重视,导致学生修完课程只能基于CPU进行软件代码设计,而对丰富的外设资源无能为力。结合学生的实际能力分析了芯片支持库的优点,这是将芯片支持库引入外设教学的重要原因。以基于MCBSP外设为例,采用芯片支持库对该外设进行操控可让学生对其功能有直观认识,同时给出了基于芯片支持库的完整设计流程,学生很容易将其推广到其他外设的设计中,这也为其今后的开发工作奠定一定的基础。
In the process of teaching DSP technology, on-chip peripherals often do not get enough attention, resulting in students finishing the course can only be based on the CPU for software code design, and the rich peripheral resources can not do anything. The advantages of the chip support library are analyzed in combination with the students’ actual ability, which is an important reason for introducing the chip support library into the peripheral teaching. Taking MCBSP based peripherals as an example, using the chip support library to manipulate this peripheral allows students to have an intuitive understanding of their functions. At the same time, a complete design flow based on the chip support library is given and students can easily generalize it to other Design, which also laid the foundation for its future development work.
