反-逆混洗光电混合循环排序网

Comega Optoelectronic Sorting Network with Recirculating Architecture

提出了一种新型光电混合循环排序网络。排序网的互连级采用自由空间光学反－逆混洗（Ｃｏｍｅｇａ）互连，比较交换节点列阵采用硅互补金属－氧化物－半导体－自由光效应器件（ＣＭＯＳ－ＳＥＥＤ）光电混合集成电路来实现。由于反－逆混洗多级网络各互连级完全相同，该排序网络通过采用循环结构大大地简化系统所需的硬件。通过采用并行比较交换节点进一步提高了排序网络中比较操作的速度。

A novel optoelectronic sorting network with recirculating architecture is presented. The link stage is implemented by optical Comega interconnect, and the array of compare and exchange(C&E) nodes is implemented by CMOS SEED hybrid integrated circuit. Basing on the fact that all link stages in Comega multistage network have the same pattern, the hardware complexity of the system is greatly reduced by introducing recirculating architecture. In addition, the comparing speed is raised by using parallel C&E nodes.
