Abstract

Once attached to a slot of a personal digital assistant PDA, a card module CM executes an application-specific program and transmits a result obtained thereby to the personal digital assistant PDA. The thus received execution result is outputted from an output part. Accordingly, the output part can be provided for shared use among several card modules CM for output of the execution result.

Claims

1. A module attachable to data terminal equipment, said module comprising:

a first storage operable to store an application-specific program;

a first processing unit operable to execute the application-specific program stored in said first storage;

a first data transmission path operable to transfer an execution result from said first processing unit; and

a first communications controller operable to communicate control information for controlling a capacity of said first data transmission path with the data terminal equipment;

wherein

said first communications controller is operable to determine the capacity of said first data transmission path based on the control information transmitted from the data terminal equipment, and then to transfer, to the data terminal equipment, the execution result by said first processing unit based on the capacity determined thereby.

2. The module according to claim 1, wherein the capacity of said first data transmission path is one selected from a group including a bit width, a frequency bandwidth, and a data rate of said first data transmission path.

3. The module according to claim 1, wherein the capacity of said first data transmission path is a number or length of packets transferred therethrough.
