[Objective]With the rapid growth of new high-throughput applications such as cloud computing,the Internet of Things,and artificial intelligence,the main applications of high-performance computing have gradually evolved from traditional scientific and engineering computing to emerging data processing,which brought huge challenges to traditional processors.High-throughput manycore processors are becoming a new type of processor architecture dealing with such applications and therefore an important research direction.[Method]In view of the above problems,this paper analyzes the typical characteristics of high-throughput applications,and discusses the key design of high-throughput many-core processors from the three core aspects of data processing,transmission,and storage.The design includes real-time task dynamic scheduling,high-density on-chip network design and on-chip storage hierarchy optimization,etc.[Results]The experimental results show that the above mechanism can effectively ensure the service quality of tasks,improve the data throughput rates,and simplify the on-chip memory hierarchy.[Conclusion]With the urgent demand for high concurrency and strong real-time processing in the era of Internet of Everything,high-throughput many-core processors are expected to become the main processing engine in future data centers.
