Embodiment Construction

[0034] The present invention is a method for realizing static library function identification in embedded software decompilation. figure 1 As shown, the specific implementation process of the present invention is explained.

[0035] 1) Function module identification:

[0036] Determine the corresponding device module according to the function module to be mapped. Because all pre-compiled device modules are stored in the device module library as files, the function module identification is to find the file name of the device module. Such as figure 2 As shown, the application described in the call graph is taken as an example, figure 2 F1, F2, F3, and F4 in the table represent the function names of the application, and the number on the arrow represents the communication volume between the two functions connected by the arrow. The information stored in the device module library of this application is as follows:

[0037] Function name

Device module name

Device module file name...

Abstract

The invention discloses a program mapping method based on reconfigurable devices of call graphs. In combination with the characteristics of a reconfigurable-device networking system, every function on a program call graph is mapped into the reconfigurable devices, and function call is transformed into the call for reconfigurable-device modules so as to achieve application mapping. The method optimizes application mapping according to traffic information, thereby helping reduce application traffic among the reconfigurable devices and improving the operating efficiency of applications; the method adopts an efficient method for calculating mapping position, thereby raising mapping speed; and the method can map different types of applications and is proved to have good practicability through repeated tests.

Description

Technical field [0001] The present invention relates to the technical field of reconfigurable devices and application program mapping technology, in particular to a method for program mapping on reconfigurable devices based on call graphs. Background technique [0002] One of the outstanding achievements of mankind in the 20th century, computer technology brought human society into the information age. With the continuous deepening of information technology and the development of semiconductor technology, the integration of chips continues to increase. In order to improve the application flexibility of chips, reconfigurable devices have appeared. [0003] A reconfigurable device is a type of computer chip. The difference between the reconfigurable device and the general chip is that the digital circuit inside the reconfigurable device can be reconfigured and decided after leaving the factory, or it can be reconfigured after a configuration, while the general computer chip has been...
