Research on software-hardware co-design methodology for USB2.0 host controller in SoC system

This paper presents a control flow oriented software/hardware co-design method and procedure,which are based on event management.With this method,the USB2.0 host controller in system-on-chip(SOC) system is designed,and the modules of scheduler unit in hardware are analyzed.The verilog hardware-description language(HDL) in resistor transistor logic(RTL) level of these modules is compiled with synopsis’s design compiler in 0.18μm CMOS technology.Compared with other similar designs,it is shown that this hardware/software co-design method can raise the potential quality and shorten the development duration of SoC chips,especially for protocol application.
