提出一种用于由双通道路由器组成的片上网络系统的网络接口。该网络接口符合AMBA总线协议,能根据IP核的通信请求,自动选取通信方式,向IP核隐藏通信细节,充分利用双通道路由器中控制包通道与数据包通道分离的特点,方便系统编程。使用SMIC0.13gm工艺综合后,该网络接151的面积仅为0.3mm^2。
An efficient design of Network Interface(NI) is proposed for the Networks-on-Chip(NoC) with two-channel routers. It is compatible of the AMBA protocol, and can choose the communication type according to the request of IP cores. It hides the communication detail to the IP core, for the sake of simplification of the software, and it can take full advantage of the two-channel router which has separate data packet channel and control packet channel. The area of the NI after synthesis is only 0.3 mm^2 in SMIC 0.13μm technology.
