    • In a data processing apparatus that switches between a secure mode and a normal mode during execution, the secure mode allowing access to secure resources to be protected, the normal mode not allowing access to the secure resources, when the secure resources increase in the secure mode, the load on a protection mechanism for protecting the resources becomes large. Thus, there is a demand for data processing apparatuses that are able to reduce secure resources.The present invention relates to a data processing apparatus that stores therein a secure program including one or more processing procedures which use secure resources and a call instruction for calling a normal program to be executed in a normal mode. While executing the secure program, the data processing apparatus calls the normal program with the call instruction and operates according to the called normal program.
    • 在执行期间在安全模式和正常模式之间切换的数据处理装置中,当安全模式下的安全资源增加时,安全模式允许访问保护资源以被保护,正常模式不允许访问安全资源 用于保护资源的保护机制的负担变大。 因此,需要能够减少安全资源的数据处理装置。 数据处理装置本发明涉及一种数据处理装置,其中存储有一个或多个使用安全资源的处理过程的安全程序和用于调用在正常模式下执行的正常程序的呼叫指令。 在执行安全程序时,数据处理装置利用呼叫指令调用正常程序,并根据所调用的正常程序进行操作。
