Flash control system based on address remapping

Abstract

The application discloses a Flash control system based on address remapping, relates to the technical field of embedded system storage management, and is used for solving the technical problems that the prior art has high delay and excessively high CPU load, drags the debugging process, and cannot meet the debugging demand of large programs; the Flash control system based on address remapping comprises an arbitrator, an address remapping table module, a space detection module and an external bus interface; the arbitrator is used for deciding the usage right of a non-Flash storage area in the Flash control system; the address remapping table module is used for saving the mapping relationship between a Flash storage area and the non-Flash storage area in the Flash control system in real time in a debugging mode; the space detection module is used for detecting the size of the unused space of the non-Flash storage area in real time in the debugging mode; and the external bus interface is used for selecting different interfaces to access the storage according to the address mapping relationship.
