具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
在现有的FPGA云产品中，用户侧一般通过云端直接向FPGA内部用户逻辑中的各处理单元发送控制数据，以进行参数配置。但是，由于控制数据分散锁存于FPGA内部的各个寄存器中，在进行FPGA数据迁移时，无法实时获取各寄存器中的控制数据，因此，无法实现FPGA数据的热迁移。
针对现有技术的缺陷，本申请提出了一种基于云的FPGA控制数据的配置方案，其主要原理是：在FPGA内部设置用于向各处理单元配置控制数据的控制模块，当用户向该FPGA配置控制数据时，通过云端将控制数据存储于该FPGA外部的存储模块中，由控制模块从外部存储模块中获取控制数据并配置到各处理单元。采用上述控制数据的配置方式，在进行FPGA数据迁移时，则可以按照普通数据的迁移方式，直接将存储于外部存储模块中的控制数据进行迁移，从而实现FPGA数据的热迁移。一方面，便于系统的运行维护；另一方面，能够避免每次FPGA迁移后对各处理单元的重新配置，以减少了用户侧的工作量，提高用户体验。
