Coarse Grained Reconfigurable Arrays (CGRAs) or Architectures are a concept for hardware accelerators based on the idea of distributing workload over Processing Elements. These processors exploit instruction level parallelism, while being energy efficient due to their simplistic internal structure. However, the incorporation into a complete computing system raises severe challenges at the hardware and software level. This article evaluates a CGRA integrated into a control engineering environment targeting a Xilinx Zynq System on Chip (SoC) in detail. Besides the actual application execution performance, the practicability of the configuration toolchain is validated. Challenges of the real-world integration are discussed and practical insights are highlighted.

UltraSynth:将CGRA集成到控制工程环境中的见解

粗粒度可重配置阵列(CGRA)或体系结构是基于在处理元素上分配工作负载的思想的硬件加速器的概念。这些处理器利用指令级并行性,同时由于其内部结构简单而具有高能效。但是,将其集成到完整的计算系统中在硬件和软件级别提出了严峻的挑战。本文详细评估了集成到针对Xilinx Zynq片上系统(SoC)的控制工程环境中的CGRA。除了实际的应用程序执行性能,还验证了配置工具链的实用性。讨论了实际集成中的挑战,并强调了实际见解。
