Advances and Applications of Hardware Specialization Techniques

如果逻辑电路的输入部分或全部是预定的，则可以优化电路以减小逻辑规模并提高最大工作频率。这种技术被称为“硬件专业化”。由于导出的电路依赖于预定的输入数据，因此采用可重配置逻辑器件（例如，FPGA）来实现专用电路。在该项目中，以下三个案例被作为硬件专业化技术的实际例子进行了研究：（1）将控制软件转换为小型和高度响应的控制系统的逻辑电路，（2）通过为每个实例提供不同的指令集，为安全应用程序提供多样化的处理器，以及（3）针对特定的应用程序和数据大小优化计算机集群配置。

If the input of logic circuit is partially or wholly predetermined, the circuit can be optimized to reduce the logic scale and to improve the maximum operational frequency. This technique is called "hardware specialization". Since the derived circuit depends on the predetermined input data, it is reasonable to adopt reconfigurable logic devices (e.g., FPGA) to implement specialized circuit. In this project, the following three cases were examined as practical examples of hardware specialization techniques : (1) conversion of control software into logic circuit for small and highly responsive control systems, (2) diversification of processor for secure applications by giving different instruction sets for each instance, and (3) optimization of computer cluster configurations for a specific set of application and data size.
