信号与系统中的matlab程序

在现行的理工科教学中,matlab的应用已经成为一个重要的内容。尤其在电子类的核心专业课信号与系统中,matlab的作用更加值得教师关注。文章就信号与系统这一课程中牵涉到的一些典型matlab程序,进行了注解和说明。试图在信号与系统和matlab的应用两方面找到了一个更为恰当的结合点,使学生和教师在专业知识和应用性工具方面,得到一个更好的处理方式。

Multiple MIPS 4Kc cores based interrupt controller design and its implementation on HDTV SoC platform

A multiple MIPS 4Kc processor cores based interrupt processing system is introduced. The interrupt controller plays a key role in the high definition television （HDTV） system-on-a-chip （SoC） platform, especially when it is a multiple processor system. Based on a general introduction to the whole HDTV SoC platform, a layered interrupt controller and its implementation are discussed in detail. The proposed scheme was implemented in our FPGA verification board. The results indicate that our scheme is reliable and efficient. Meanwhile, as a functional intellectual property （IP）, the interrupt controller has reusability and expandability with the layered structure.
