Abstract

There is currently great interest in using systems of FPGAs for logic emulators, custom computing devices, and software accelerators. An important step in making these technologies more generally useful is to develop completely automatic mapping tools from high-level specifications to FPGA programming files. We examine one step in this automatic mapping process, the selection of FPGA pins to use for routing inter-FPGA signals. We present an algorithm that greatly increases mapping speed while also improving mapping quality.<>
多fpga系统的引脚分配
目前有很大的兴趣使用fpga系统的逻辑模拟器,自定义计算设备,和软件加速器。使这些技术更普遍有用的一个重要步骤是开发从高级规范到FPGA编程文件的全自动映射工具。我们研究了自动映射过程中的一个步骤,即选择用于路由FPGA间信号的FPGA引脚。我们提出了一种算法,大大提高了映射速度,同时也提高了映射质量。
