摘　　要：采用免费软核LEON2作为数字机顶盒的CPU可以降低产品成本。为了使LEON2软核能更快更好地应用于数字机顶盒,选择先在FPGA开发板上建立基于LEON2处理器的一个原型,通过这个原型对硬件性能进行仿真,并且还可以在线修改程序,这样就很容易验证系统的性能,加速软件开发调试流程。经过在FPGA开发板上的仿真,对基于LEON2的系统测试取得了预期的效果。Selecting free IP core LEON2 for CPU of Digital Set- top Box （STB） can reduce the cost. For LEON2 applied to STB faster and better,firstly prefer to set up a prototype based on LEON2 processor on FPGA, through the prototype to emulate the hardware capability, and to modify program online, afterward validate the system capability easily, and the flow of program exploitation can be accelerated. A prospective effect of test to the system based on LEON2 through the FPGA simulation is gained.
