Description

Inter-cluster communication optical interconnection network in reconfigurable array processor

Technical Field

The invention belongs to the technical field of integrated circuit design, and particularly relates to parallel access of communication among processing element clusters formed by 4*4 in a 16-by-16 processor array.

Background

In order to improve the performance of the system, it has proven to be an effective approach to integrate multiple processor cores on a single chip, but as integrated circuit processes further develop, the system on a chip can integrate hundreds or thousands of processor cores, and the overall performance of the system is still significantly improved by increasing the number of processor cores. With the increasing number of processor cores integrated on a chip, memory issues are becoming increasingly critical to the overall performance of the system on a chip. Under deep submicron processes, interconnect delay has exceeded logic gate delay, which becomes a bottleneck to increase the operating frequency of the system.

On one hand, the cluster-based NoC (Network on Chip) interconnection mode has larger data access delay, and the read/write delay is generally up to tens of clock cycles, which is too large compared with 1-2 cycles of operation level or data level operation, meanwhile, the data access delay is related to the distance between communication nodes, and longer communication distance leads to longer interconnection line delay, so that the real-time requirement of application is difficult to meet; on the other hand, in a light core array processor, the circuit scale of a single processing unit is about 2000 logic units, and a 4-channel virtual channel router occupies about six times of the processing unit, so that the communication resource is far greater than the computing resource, and the resource utilization rate is low.

The optical signal is suitable for long-distance communication due to the characteristics of low transmission delay and low power consumption, and the reconfigurable array processor inter-cluster communication optical interconnection network aims at the problem of larger inter-cluster communication access delay, fully considers the parallelism of the inter-cluster access of the processing element, and realizes the parallel access of 16 processing element clusters by adopting a wavelength division multiplexing technology and a four-level optical switch.
