%X Aiming at the problem of poor processing performance of open source of the fifth generation of mobile communications system(5G) under general processor, the characteristics of open source 5G are studied and the architecture of heterogeneous computing acceleration is proposed. This proposed architecture separates the upper layer and the physical layer of the air interface protocol stack, and modularizes physical layer functions of the open source 5G. Utilizing the advantages of general processor on processing upper protocol stack, heterogeneous hardware is introduced to accelerate physical layer function modules, which is demanding for computing resources. The concept of heterogeneous physical layer and the algorithm of adaptive allocation of computing resources are introduced into the architecture. Then, the heterogeneous accelerated open source 5G software platform is implemented for the first time based on OpenAirInterface platform. The actual tests of channel codec and modulation modules show that the proposed heterogeneous acceleration architecture can significantly improve the processing performance of physical layer compared with general purpose processor architecture.
