ABSTRACT:
A data storage mechanism is provided where a plurality of data items are stored in a plurality of register elements. Each registered element is capable of storing at least one data item. The plurality of register elements is arranged to form a sequence of register elements. First data is stored in a first part of the sequence and second data is stored in a second part of the sequence. The first part and the second part are of variable lengths with the sum of the variable lengths being equal to the lengths of the sequence of register elements. Thus, a double-ended queue mechanism is provided which may be used to store data of different type or data which is either scheduled periodically or asynchronously. The mechanism may be used in a USB 2.0 compliant host controller.
