工业过程控制是现场可编程门阵列（FPGA）尚未开发的市场。用于工业过程控制的程序传统上以称为继电器梯形逻辑的图形语言编写，并在可编程逻辑控制器（PLC）上实现。将梯形图逻辑映射到典型的FPGA是一个漫长的过程，并且结果很难验证。提出了一种直接实现梯形继电器逻辑的FPGA结构。转换到布尔代数是消除。技术映射简单而直接。布局和布线也比一般的FPGA情况简单得多。该架构可扩展到不同大小和资源的设备。本文介绍了FPGA的体系结构，以及它在高性能工业过程控制中的作用。
Industrial process control is an untapped market for field programmable gate arrays (FPGAs). Programs used for industrial process control are traditionally written in a graphical language called relay ladder logic, and implemented on programmable logic controllers (PLCs). The mapping of ladder logic onto typical FPGAs is a lengthy process, and results are hard to verify. We propose an FPGA architecture implementing relay ladder logic directly. Conversion to Boolean algebra is eliminated. Technology mapping is simple and direct. Placement and routing are also considerably simpler than in the general FPGA case. The architecture scales to devices of differing sizes and resources. This paper describes the FPGA architecture, and its role in high performance industrial process control.
