Abstract:
1. An apparatus for generating pointers for transfer of structured data in an asynchronous transfer mode (ATM) adaptation layer Type 1 (AAL1), comprising: a next-cycle boundary generating means for generating a next-cycle boundary value, using a pointer value and a “Pointer_P” value in order to store a sequence of ATM cells; a modulo calculating means for calculating a modulo obtained by dividing the next-cycle boundary value received from the next-cycle boundary generating means by an externally-received block size value; a current-cycle boundary generating means for generating a current-cycle boundary value, using the next-cycle boundary value received from the next-cycle boundary generating means, the modulo received from the modulo calculating means, and the block size value; a pointer calculating means for generating a pointer value for determination of structure boundaries and a “Pointer_P” value, to be supplied to the next-cycle boundary generating means, based on the current-cycle boundary value received from the current-cycle boundary generating means; and a control signal generating means for receiving a sequence number signal and a start signal and generating enable signals and control signals to be provided to the next-cycle boundary generating means and the current-cycle boundary generating means.
