背景技术Background technique
为了提升系统的性能，通过在单一芯片上集成多个处理器核，被证明是行之有效的途径，但随着集成电路工艺的进一步发展，片上系统可集成成百上千的处理器核心，继续通过提升处理器核心数，对系统整体性能的提升已经微不足道。随着片上集成的处理器核心数目的不断提升，存储问题越来越成为制约片上系统整体性能的关键。到深亚微米工艺下，互连线延迟已经超过逻辑门延迟，成为提升系统工作频率的瓶颈。In order to improve the performance of the system, it is proved to be an effective way to integrate multiple processor cores on a single chip. However, with the further development of integrated circuit technology, the system on a chip can integrate hundreds of processor cores. By continuing to increase the number of processor cores, the improvement of the overall performance of the system is negligible. With the continuous improvement of the number of processor cores integrated on a chip, the storage problem has increasingly become the key to restricting the overall performance of the system on a chip. In the deep sub-micron process, the delay of the interconnect line has exceeded the delay of the logic gate, and has become a bottleneck for increasing the operating frequency of the system.
基于簇的NoC(Network on Chip)互连方式，一方面，数据访问延时较大，一般读/写延时高达数十个时钟周期，这与操作级或是数据级运算的1～2个周期相比，延时太大，同时数据访问延迟与通信节点距离有关，较长的通信距离将导致较长的互连线延迟，导致难以满足应用的实时性需求；另一方面，轻核阵列处理器，单个处理单元的电路规模大概在2000个逻辑单元，而4通道的虚通道路由器占用资源大概是处理单元的六倍，导致通信资源远远大于计算资源，资源利用率低下。Cluster-based NoC (Network on Chip) interconnection method, on the one hand, the data access delay is relatively large, and the general read/write delay is as high as dozens of clock cycles, which is different from the operation-level or data-level operations. Compared with the cycle, the delay is too large, and the data access delay is related to the distance of the communication node. A longer communication distance will lead to a longer delay of the interconnection line, making it difficult to meet the real-time requirements of the application; on the other hand, the light-core array For a processor, the circuit size of a single processing unit is about 2,000 logic units, while a 4-channel virtual channel router occupies about six times the resources of a processing unit, resulting in communication resources being far greater than computing resources, and resource utilization is low.
光信号由于其传输延时低、功耗小的特点，适合于远距离通信，可重构阵列处理器簇间通信光互连网络针对簇间通信访问延迟较大的问题，充分考虑处理元簇间访问的并行性，采用波分复用技术，通过四级光交换开关，实现了16个处理元簇的并行访问。Optical signals are suitable for long-distance communication due to their low transmission delay and low power consumption. Reconfigurable array processor inter-cluster communication optical interconnection network Aiming at the problem of large inter-cluster communication access delay, fully consider the processing element cluster The parallelism of inter-access, using wavelength division multiplexing technology, realizes the parallel access of 16 processing element clusters through four-level optical switching switches.
