近些年出现了不少domain specific accelerator,比如赛灵思(Xilinux)的深度学习FPGA加速卡,谷歌的TPU,这些加速器中必不可少的单元就是systolic array。NVIDIA的volta 架构,被称为第一个以deep learning为核心的架构,就是因为tensor core的加入,而tensor array实际上就是sytolic array。今天我们就来看看这个systolic array。
最近在开发VCK190时,发现Xilinx Versal系列的AI engine(AIE),其实和Systolic Array(SA)有着很相似的地方。Xilinx工程师在研发AIE时,应该是有所借鉴SA的。 Systolic Array最早是H. T. Kung于1982年在论文《W…

Systolic Architectures，特别是它们在domain specific accelerator中的应用，如赛灵思的FPGA和谷歌的TPU中，是近年来的一大焦点。NVIDIA的Volta架构就是通过引入tensor cores，实质上是systolic arrays，推动了这一领域的革新。本文将深入探讨systolic array的概念、原理以及在卷积计算中的应用，以及它在硬件优化中...
Systolic array HLS还提供了一些工具和库,可以帮助用户进行代码生成、仿真和验证。这些工具可以生成可编译的硬件描述语言代码,并使用模拟器或FPGA硬件进行仿真和验证。 总之,Systolic array HLS是一种强大的工具,可以用于设计和实现高性能的Systolic array系统。通过使用Systolic array HLS,用户可以更好地理解和控制并行处理...

The implementation uses a systolic array approach, where linearly connected processing elements compute distinct contributions to the outer product of tiles of the output matrix. The approach used to implement this kernel was presented atFPGA'20[1]. For a general description of the optimization techni...
configurable logic array. The systolic array operates in two phases. In the first phase, a sequence comparison array due to Lopresti [2] is used to compute a matrix of distances which is stored in local RAM. In the sec- ond phase, the stored distances are used by the alignment ...
