Abstrat: This paper mainly discusses the design and implementation of controlling module in 32 bit embedded FPU, and introduces the architecture of controller and feature of the current. The design is implemented by micro program method. In the design, there are many techniques used such as: multi-address entrance. In order to improving the performance of it, the design is implemented by gate level. Finally, it is shown that the controller of the FPU is much suitable for embedded application due to its small area and hign speed from its layout.
