    • PROBLEM TO BE SOLVED: To resolve conflicts of a crossbar circuit.SOLUTION: The crossbar circuit has an array of data input routes 12 and data output routes 50, and at each intersection, a crossbar cell 20 including a configuration storage circuit programmable to store a routing value, a transmission circuit, and an arbitration circuit is provided. The arbitration circuit is operated in combination with the arbitration circuit of other crossbar cells associated with the same data output route to selectively modify a voltage on a plurality of bit lines in order to apply an adaptive priority scheme. When there are a plurality of transmission requests in the same data output route, the configuration storage circuit of the only crossbar cell associated with the same data output route has a routing value programmed to a first value, and conflicts among the plurality of transmission requests are resolved according to the adaptive priority scheme. Further, each crossbar cell includes a priority storage circuit.
    • 解决问题:解决交叉开关电路的冲突。 解决方案:交叉开关电路具有数据输入路径12和数据输出路径50的阵列,并且在每个交点处,包括可编程以存储路由值的配置存储电路的交叉开关单元20,发送电路和仲裁 提供电路。 仲裁电路与与相同数据输出路由相关联的其他交叉电池单元的仲裁电路组合操作,以选择性地修改多个位线上的电压,以便应用自适应优先级方案。 当在相同的数据输出路由中存在多个发送请求时,与相同的数据输出路由相关联的唯一交叉开关单元的配置存储电路具有被编程为第一值的路由值,并且多个发送请求之间的冲突是 根据自适应优先方案解决。 此外,每个交叉开关单元包括优先级存储电路。 版权所有(C)2012,JPO&INPIT
