Portable compact device
First Claim
1. A portable compact device for use with an external device supplying input data having a data structure consisting of said input data and associated indicating data which indicates the data type and stored address for the input data comprising:
- interface means for providing an interface between an external device and the portable compact device;
data memory means for storing the input data received by said interface means at an address corresponding to the indicating data;
processing means coupled to the data memory means for receiving and sending the data between said interface means and said data memory means, the processing means including;
control means for processing data stored in the data memory means in accordance with the indicating data and determining whether the data structure in the data memory means allows for the processing of the input data by the control means; and
initializing means for establishing an initialized data structure in the data memory means when the control means determines that the data structure does not allow for the processing of the input data, the initialized data structure corresponding to an indicating data which indicates the data type and stored address which allows for the processing of the data stored in the data memory means.

Abstract
A portable compact device for use with an external device. The portable compact device includes an interface circuit for providing an interface between an external device and the portable compact device. A data memory circuit stores data received by the interface circuit. A control circuit coupled to the data memory circuit processes data stored in the data memory circuit in accordance with a stored data structure. A data modifying circuit is coupled to the data memory circuit for modifying the stored data. A data structure initializing circuit insures that the structure of the stored data in the data memory circuit allows the control circuit to process the stored data.
