虚拟硬件是一种通过使用扩展的现场可编程栅极阵列（FPGA）技术实现带有小型真实硬件的大型数字电路的技术。 FPGA芯片内提供了几个配置RAM模块，并且可以通过更换活动模块来快速更改门阵列的配置。用于配置的数据将从芯片备份RAM传输到未使用的配置RAM模块。一种称为WASMII的新型计算机制，该机制是直接执行目标数据流图的，它是根据虚拟硬件提出的。 WASMII芯片由虚拟硬件的FPGA组成，以及以数据驱动方式替换配置RAM模块的其他机制。配置数据由以静态调度预处理器预先分配的顺序预加载。通过连接许多WASMII芯片，可以很容易地构建高度平行系统。<< etx >>
Virtual hardware is a technique to realize a large digital circuit with a small real hardware by using an extended Field Programmable Gate Array (FPGA) technology. Several configuration RAM modules are provided inside the FPGA chip, and the configuration of the gate array can be rapidly changed by replacing the active module. Data for configuration are transferred from an off-chip backup RAM to an unused configuration RAM module. A novel computation mechanism called the WASMII, which executes a target data flow graph directly, is proposed on the basis of the virtual hardware. A WASMII chip consists of the FPGA for virtual hardware and the additional mechanism to replace configuration RAM modules in the data driven manner. Configuration data are preloaded by the order which is assigned in advance with a static scheduling preprocessor. By connecting a number of WASMII chips, a highly parallel system can be easily constructed.<<ETX>>
