AN FPGA-BASED SIMULATION AND IMPLEMENTATION OF THE AAL TYPE 2 RECEIVER

This paper describes a hardware implementation of an ATM Adaptation Layer (AAL) type 2 receiver. The simulation performance of the developed prototype is measured with real AAL type 2 encoded material and compared to two software-based AAL type 2 receiver implementations. The advantages and disadvantages of hardware-based and softwarebased simulation approaches in product development and prototyping are discussed. In the beginning the principles of AAL type 2 are presented.
