    • A laminated lens package and a method of fabricating the same are disclosed. The laminated lens package includes a first lens layer including a first lens element formed at one surface thereof through a first mold; a second lens layer including a second lens element formed at one surface thereof through a second mold, corresponding to a location of the first lens element; and a polymer layer provided between the first lens layer and the second lens layer. Accordingly, desired refraction can be implemented by controlling a refractive index. Also, since no spacers are used, defects caused by adhesion of an adhesive agent do not occur. Thus, a fabrication process is simplified, so that productivity can be improved and a fabrication cost can be reduced.
    • 公开了层压透镜封装及其制造方法。 层叠透镜封装包括:第一透镜层,包括通过第一模具形成在其一个表面上的第一透镜元件; 第二透镜层,包括对应于第一透镜元件的位置的通过第二模具形成在其一个表面上的第二透镜元件; 以及设置在第一透镜层和第二透镜层之间的聚合物层。 因此,可以通过控制折射率来实现期望的折射。 此外,由于不使用间隔物,不会发生由粘合剂的粘附引起的缺陷。 因此,简化了制造工艺,从而可以提高生产率并且可以降低制造成本。

    • A content addressable merged queue (camQ) architecture for high-speed switch fabrics reduces the memory requirement for crossbar switch input and output queues using memory cells and age tag comparators. CamQ emulates VOQ FIFO for each supporting priority, eliminating HOL blocking. Multiple QoS levels are supported cost effectively at higher traffic bandwidth limits. Content addressable memory (CAM) cells store payload destinations, which can be addressed by cell priorities. Once a priority for QoS is decided, all the cells with the selected priority in the payload can make connection requests to destination ports directly through the CAM structure. An age tag is assigned to incoming cells and fast age tag comparators provide FCFS features by selecting the oldest cell. Small memory sizes prevent the bottlenecking in ingress and egress queues. A CIOQ crossbar has a fast switching speed, emulating a FIFO output queue switch. Age and priority are interleaved to schedule switching.
    • 用于高速交换结构的内容可寻址合并队列(camQ)架构减少了使用存储器单元和年龄标签比较器的交叉开关输入和输出队列的存储器需求。 CamQ模拟每个支持优先级的VOQ FIFO,从而消除了HOL阻塞。 在更高的流量带宽限制下,可以以成本有效的方式支持多个QoS级别。 内容可寻址存储器(CAM)单元存储有效载荷目的地,其可以通过小区优先级来寻址。 一旦确定了QoS的优先级,则有效载荷中具有选定优先级的所有小区可以直接通过CAM结构向目的端口发送连接请求。 年龄标签被分配给传入的单元格,快速年龄标签比较器通过选择最旧的单元格来提供FCFS功能。 小内存大小可防止入口和出口队列中的瓶颈。 CIOQ交叉开关具有快速切换速度,仿真FIFO输出队列开关。 年龄和优先级被交织以调度切换。
