A reconfigurable system configuration controller and a pipeline scheduling method thereof

Abstract

The invention provides a reconfigurable system configuration controller comprising: a configuration storage module which comprises a configuration packet storage device and a configuration group storage device, wherein the configuration packet storage device is used for storing configuration packets and the configuration group storage device is used for storing configuration groups; a configuration packet analysis module used for analyzing the configuration packets, generating configuration group indexes and configuration group effective flag bits and outputting the same to a configuration group reading module; the configuration group reading module used for reading effective configuration groups from the configuration group storage device according to the configuration group indexes and the configuration group effective flag bits; a configuration group reconfiguration module used for starting or stopping a reconfiguration process and a pipeline execution process of calculating arrays according to whether the configuration groups are in position or not and whether input data are in position or net. The reconfigurable system configuration controller can reduce power consumption of reconfigurable systems and improve the calculating performance of reconfigurable systems.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a reconfigurable system configuration controller and a pipeline scheduling method thereof. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the speed and flexibility of computing technology. Because reconfigurable technology can use software programming to realize the spatial mapping from algorithms to computing engines, the universal integrated circuit can still be used after it is manufactured. With the ability to customize, it can meet the needs of different algorithms in a timely manner, and has been more and more widely used. [0003] In the computing process of the reconfigurable system, the reconfigurable computing array needs to be configured according to the data flow graph. With the increasingly complex application-oriented calculations of reconfigurable systems, the amount of calculat...
