Abstract:

[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 many-core 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.
