基于Microblaze处理器的浮点内积运算设计

Design of floating-point inner product based Microblaze processor

浮点内积运算在信号处理与图像处理中有着广泛的应用,本文利用软核处理器灵活性和可扩展性的特点,介绍了基于Microblaze处理器的浮点内积运算结构,设计采用IEEE-754双精度浮点数,通过对DSA电路改进设计出了适合于内积运算的累加电路结构。通过EDK设计平台,在SOPC系统中把内积运算单元通过FSL总线挂载到Microblaze软核处理器上,实现了硬件单元的调用。

floating-point inner product is widely applied in signal processing and image processing,this paper introduces architecture for floating-point inner product,this design is fully used of the flexible and scalability in software processor,this paper also introduces one reduction circuit which applies in floating-point inner product through improving DSA circuit.At last,we connect this computing unit to processor through FSL bus,and realize the soft-core processor called the hardware unit.
