应用NiosII嵌入式软核处理器所具有的可自定义指令的特点,本文提出了一种具有常规DSP功能的NiosII系统SOPC解决方案。用户可通过Matlab和DSP Builder或VHDL语言来设计复数乘法器、整数乘法器、浮点乘法器等硬件模块,再将它们定制为相应的指令,从而实现软件的灵活性和硬件高速性的结合。
Application NiosII embedded soft-core processor has the characteristics of customizable instructions, this paper presents a conventional DSP functions NiosII system SOPC solution. Users can design complex multipliers, integer multipliers, floating-point multipliers and other hardware modules through Matlab and DSP Builder or VHDL language, and then customize them to the corresponding instructions in order to achieve the combination of software flexibility and hardware speed.
