页导向光学存储器中可实现的高数据传输速率需要能够有效处理数据的逻辑电路的并行接口。光学可编程门阵列是传统 FPGA 的增强版本,利用由 VCSEL 阵列访问的全息存储器来对其逻辑进行编程。 OPGA 模块结合空间复用和移位复用将配置页存储在存储器中,非常紧凑,并且配置时间极短,允许动态重新配置。 OPGA 的重构能力可用于更有效地解决模式识别和数字分类中的问题。
The high data transfer rate achievable in page-oriented optical memories demands for parallel interfaces to logic circuits able to process efficiently the data. The Optically Programmable Gate Array, an enhanced version of a conventional FPGA, utilizes a holographic memory accessed by an array of VCSELs to program its logic. Combining spatial and shift multiplexing to store the configuration pages in the memory, the OPGA module is very compact and has extremely short configuration time allowing for dynamic reconfiguration. The reconfiguration capability of the OPGA can be applied to solve more efficiently problems in pattern recognition and digit classification.
