Zikang Song, Haibin Wu, Dongrui Fan · 2024
Multiple-Input Multiple-Output (MIMO) technol-ogy is extensively used in various communication scenarios, posing challenges to the flexibility and real-time performance of its hardware solutions. In this paper, we propose a reconfigurable dataflow baseband processor which can flexibly deploy and efficiently execute operators extracted from MIMO communication system using dataflow graphs. Experimental results demonstrate that the proposed design offers high flexibility and strong real-time performance. Additionally, it achieves 2.38×and 1.80× improvement in energy efficiency compared to similar reconfig-urable architecture and ASIC, respectively, with an antenna size of 128×8.
