Problems solved by technology

However, most of the existing dynamic reconfigurable systems adopt bus-based or fast single link (Fast Simplex Link, FSL) interconnection mode. Although the functions of the reconfigurable processing unit can be dynamically configured, the interface communication bandwidth is limited and the system structure is fixed. constant
It is the mismatch between the interface design method and the data flow computing characteristics, the mismatch between the fixed system structure and the data flow computing mode, which cannot meet the processing requirements of various data flow computing modes, so that the performance of data flow-driven applications cannot be effectively obtained. promotion

Abstract

The invention relates to the technical field of reconfigurable circuits and systems, and discloses a dynamic reconfigurable system adaptable to a plurality of dataflow computation modes and an operating method. The dynamic reconfigurable system comprises an embedded microprocessor, a configuration controller, a multi-port memory controller and a plurality of reconfigurable processing units. A dataflow communication interface and a control interface, which can be separated, are adopted for each reconfigurable processing unit, so that the embedded microprocessor can be used for dynamically configuring the functions and interconnection structure of each reconfigurable processing unit to be adapted to the dataflow computation modes. Compared with the conventional system with a bus and a fast simplex link (FSL) structure, the system has the advantages that the resource reconfigurability of a field programmable gate array (FPGA) is fully utilized, and functions and structures, which are matched with the dataflow computation modes, are configured during operation to improve a communication bandwidth and the processing performance of dataflow driving application; and moreover, the system is high in structural adaptability and expansibility, and the invention is significant for a dataflow processing-oriented dynamic reconfigurable system.

Description

technical field [0001] The invention relates to the technical field of reconfigurable circuits and systems, in particular to a dynamic reconfigurable system and an operation method that can adapt to various data flow computing modes. Background technique [0002] Since the field programmable gate array (Field Programmable Gate Array, FPGA)-based dynamic reconfigurable system was proposed, it has shown good performance in data flow-driven applications such as data encryption / decryption processing, multimedia processing, and digital signal processing. computing performance and reconfigurable flexibility. The data stream processing module in the above applications is usually implemented by using three basic data stream computing modes: Fork-Join, Pipeline and Feedback Loop, or a combination of the above data stream computing modes. [0003] In recent years, with the continuous expansion of the FPGA scale, the dynamic reconfigurable system can accommodate multiple coarse-graine...
