以纯光学蝶互连结构实现的二进制全加器为基础,提出光电混合互连的新构想,即用光电混合的蝶互连网络取代纯光蝶互连网络以实现二进制全加运算。这种改进的蝶互连结构,既发挥了光互连网络在并行运算中的优势,又利用了电互连网络来弥补光互连网络实现上的不足。另外还设计了用以实现“与”、“或”逻辑运算的光电处理电路,给出其实验结果及用此结构实现二进制全加运算的计算机模拟结果。
Based on the binary full adder realized by the pure optical butterfly interconnect structure, a new concept of optoelectronic hybrid interconnection is proposed, that is, the optoelectronic butterfly interconnection network is used to replace the pure optical butterfly interconnection network to realize the binary addition operation. This improved butterfly interconnect structure not only takes advantage of the optical interconnection network in parallel computing, but also utilizes the electrical interconnection network to make up for the shortcomings of the optical interconnection network. In addition, the optoelectronic processing circuit for “AND”, “OR” logic operation is also designed, and the experimental results and the computer simulation result of using this structure to realize the binary addition operation are given.
