使用里德-所罗门解码器的例子,我们提供了什么类型的硬件结构需要生成,以实现特定的性能目标的见解。由于存在运行时依赖性,有时不清楚如何重构C代码,以便合成工具可以推断出所需的硬件结构。这样的硬件结构很容易用HDL表示。我们提出了一个实现在Bluespec,一个高层次的HDL,并显示了7.8倍的性能提高,而使用只有0.45倍的面积的基于C的实现。
Using the example of a Reed-Solomon decoder, we provide insights into what type of hardware structures are needed to be generated to achieve specific performance targets. Due to the presence of run-time dependencies, sometimes it is not clear how the C code can be restructured so that a synthesis tool can infer the desired hardware structure. Such hardware structures are easy to express in an HDL. We present an implementation in Bluespec, a high-level HDL, and show a 7.8× improvement in performance while using only 0.45× area of a C-based implementation.
