Programmable optically reconfigurable gate array and its writer

最近，光学可重构门阵列（ORGAs），它包括一个门阵列VLSI，全息存储器，和激光阵列，已经开发出实现巨大的虚拟门数，大大超过目前可用的VLSI。通过利用全息存储器的大存储容量，可以生产具有超过1万亿门数的超大规模集成电路。然而，与目前的现场可编程门阵列（FPGA）相比，传统的ORGAs有一个重要的缺点：它们不能在制造后重新编程。为了重新编程ORGA，全息存储器必须从其ORGA包中拆卸，然后使用全息存储器写入器在ORGA包外部重新编程。然后，必须使用高精度技术将其实现到ORGA封装上，而这些技术超出了手动组装所能提供的。因此，为了改善此缺点，本研究展示了世界上第一个可程式化的无拆解ORGA架构及其写入器系统。

Recently, optically reconfigurable gate arrays (ORGAs), which consist of a gate array VLSI, a holographic memory, and a laser array, have been developed to achieve huge virtual gate counts that vastly surpass those of currently available VLSIs. By exploiting the large storage capacity of a holographic memory, a VLSI with more than 1 tera-gate count will be producible. However, compared with current field programmable gate arrays (FPGAs), conventional ORGAs have one important shortcoming : they cannot be reprogrammed after fabrication. To reprogram ORGAs, a holographic memory must be disassembled from its ORGA package, then reprogrammed outside of the ORGA package using a holographic memory writer. It must then be implemented onto the ORGA package with high precision techniques beyond that which can be provided by manual assembly. Therefore, to improve that shortcoming, this research has demonstrated the world's first programmable ORGA architecture with no disassembly and its writer system.
