Abstract

In this paper, we design IP of ATM AAL layer for B-ISDN. The designed ATM AAL module supports the function for AAL type 0, AAL type 3/4, AAL type 5. The designed IP provides for automatic CRC-32 and CRC-10 for AAL type and AAL type 3/4. Also our IP inserts and extracts the header and trailer for each type automatically. After HDL description, it is verified by the simulation. The designed U is implemented in Xilinx FPGA. Rx AAL module operates at 35MHz and Rx AAL module operates at 50MHz. The designed IP can be applicable in high-speed ATM SAR(Segmentation and Reassembly) chip.
