Abstract
An embedded operating system of smart card and the method for processsing task are disclosed. The method includes: A, initializing the system; B, creating at least one task according to the function set by the system; C, scheduling the pre-execution task according to the priority of the system; D, executing the task and returning the executing result through a data transmission channel. The invention enchances the support of the data channel of the hardware platform, and not only supports the single data channel, ISO7816, of conventional smart cards, but also supports the status of two or more data channels coexisting, in order to make the smart card transmit the information more flexible with higher speed with device terminals. The invention enchances the support of application of smart card, and not only supports the single application on the conventional smart card, but also supports several applications running simultaneity on one card, in order to utilize the smart card with higher efficiency.
