    • A field device, comprising a sensor, and a control/evaluation unit. The control/evaluation unit is implemented on an application-specific integrated circuit—an ASIC—which, in at least a first section and in a second section, is embodied as a dynamically reconfigurable logic chip. In each of the two sections, in each case, a measuring path composed of a plurality of function modules can be configured; wherein the individual sections are spaced apart from one another in such a manner, that a temperature and/or a voltage change in one of the sections has no influence on the other section or the other sections. The control/evaluation unit partially dynamically reconfigures the function modules in the measuring paths as a function of the particular defined safety-critical application, so that the field device fulfills the required safety standard.
    • 包括传感器和控制/评估单元的现场设备。 控制/评估单元在专用集成电路(ASIC)上实现,ASIC至少在第一部分和第二部分被实现为动态可重配置的逻辑芯片。 在这两个部分中的每一个中,在每种情况下,可以配置由多个功能模块组成的测量路径; 其中各个部分以这样的方式彼此间隔开,使得其中一个部分中的温度和/或电压变化对另一部分或其它部分没有影响。 控制/评估单元根据特定的安全关键应用部分动态地重新配置测量路径中的功能模块,从而现场设备满足所需的安全标准。

    • Techniques for remotely programming a field programmable gate array, or FPGA, are described. A field programmable gate array uses operating software which is stored in a memory such as a parallel flash memory. Upon power up or reset of the FPGA, the operating software is converted to serial form and loaded into the FPGA, where it is used to control the operations of the FPGA. When it is desired to update the operating software, an updated operating software package is transferred from a remote location to a terminal associated with the FPGA. The FPGA then retrieves the updated operating software from the terminal over a connection such as a universal serial bus (USB) connection and transfers it to the flash memory, overwriting the previously installed operating software. Upon a subsequent power up or reset of the FPGA, the updated operating software is loaded into the FPGA.
    • 描述用于远程编程现场可编程门阵列或FPGA的技术。 现场可编程门阵列使用存储在诸如并行闪存的存储器中的操作软件。 在FPGA上电或复位时,操作软件将转换为串行形式并加载到FPGA中,用于控制FPGA的操作。 当需要更新操作软件时,更新的操作软件包从远程位置传送到与FPGA相关联的终端。 然后,FPGA通过诸如通用串行总线(USB)连接的连接从终端检索更新的操作软件,并将其传送到闪存,覆盖以前安装的操作软件。 在随后上电或复位FPGA时,更新的操作软件将加载到FPGA中。
