Dynamic reconfiguration supporting method, dynamic reconfiguration supporting apparatus, and dynamic reconfiguration system
View Patent ↗A dynamic reconfiguration supporting method that generates a driver function to cause a dynamic reconfiguration circuit to execute a program of an application described in a predetermined language, includes acquiring a configuration defining file representing a configuration of a cluster of the dynamic reconfiguration circuit in execution of the process of the application, generating an address map representing an address of a processing element (to be referred to as “PE” hereinafter) in the cluster on the basis of the configuration defining file acquired by the acquiring operation, generating a driver function that associates the function and an address of the PE which executes the function with reference to the address map, when a PE which executes a function described in the application is allocated from the PE, and creating a driver function file that stores the driver function.
1. A dynamic reconfiguration supporting method that generates a driver function to cause a dynamic reconfiguration circuit to execute a program of an application described in a predetermined language, comprising:
acquiring a configuration defining file representing a configuration of a cluster of the dynamic reconfiguration circuit in execution of the process of the application;
generating an address map representing an address of a processing element in the cluster on the basis of the configuration defining file;
generating a driver function that associates the function and the address of the processing element which executes the function with reference to the address map, when a processing element which executes a function described in the application is allocated from the processing element; and
creating a driver function file that stores the driver function, further comprising:
storing the driver function file and an execution code that executes the process of the application in a predetermined memory; and
replacing the address of a processing element of the execution code executed by the dynamic reconfiguration circuit with an address of a processing element of the dynamic reconfiguration circuit with reference to the driver function file stored in the predetermined memory.
2. A dynamic reconfiguration supporting system that supports execution of a process of an application described in a predetermined language, a circuit configuration of a dynamic reconfiguration circuit including a cluster having a processing element being able to be changed, comprising:
a dynamic reconfiguration supporting apparatus that includes
an acquirer that acquires a configuration defining file representing a configuration of a cluster of the dynamic reconfiguration circuit in execution of the process of the application,
an address map generator that generates an address map representing an address of a processing element in the cluster on the basis of the configuration defining file,
a driver function generator that, when a processing element which executes a function described in the application is allocated from the processing element, generates a driver function that associates the function and an address of the processing element which executes the function with reference to the address map, and
a driver function file creator that creates a driver function file contains the driver function;
a storage that stores an execution code to execute the process of the application and the driver function file;
an executor that reads the execution code from the storage to execute the execution code when the execution unit accepts an execution designation of the application; and
a replacer that replaces an address of a processing element of the execution code with an address of a processing element of the dynamic reconfiguration circuit with reference to the driver function file stored in the storage in execution of the execution code by the executor.
