摘要
交换器是PCI Express中出现的全新的控制单元,可以使PCI Express数据包从任何设备路由到其他设备.根据PCI Express1.0a规范对PCI Express交换器的交换应用逻辑模块进行设计,其由路由模块、TC/VC映射模块和仲裁三个模块组成.此模块可以与开关核一同构成交换器.各模块运用硬件描述语言Verilog HDL实现,并用ModelSim进行仿真得出了仿真波形,验证了设计的正确性.
Switch is a new control unit in PCI Express which can route PCI Express packets from any device to any other device. In this paper, switch application logic module of PCI Express switch is designed according to the PCI Express base specification, revision 1.0a. It is composed of route, TC/VC mapping and arbitration. This module can compose switch together with three instance of SW core. The module is described with Verilog HDL and simulated by modelsim. The results validate its correctness.
