Application program calling system and method

Abstract

The invention discloses an application program calling system and method. The system comprises a host end and a chip end, the host end stores a first code of a first type of application program and a second code of a second type of application program, the chip end stores a third code of the second type of application program, the first code is a complete function code of the first type of application program, and the second code is a starting function code of the second type of application program. The third code is a complete function code of the second type of application program; the host end is used for sending a first request which is used for calling a first type of target application programs and comprises a first target code to the chip end, and sending a second request which is used for calling a second type of target application programs and comprises a second target code to the chip end; the chip end is used for responding to the first request and running the first target code; and in response to the second request, determining and running a third target code corresponding to the second target code from the third code. The technical problem of lack of security protection for application codes in related technologies is solved.
