ATM AAL-2 chip design for video applications over ATM network

We have designed and implemented two ASICs for the functions of the ATM Adaptation Layer (AAL) type 2 protocol. The SAR-T chip is for the transmitter with 8-bit pipeline operation; and the SAR-R chips is for the receiver with 8-bit or 16-bit operation. The speed of both chips can be up to 160 Mbps. The SAR-T and SAR-R chips not only connect a buffer and the DS3 framer (PLPP) in an ATM network, they also accept the data from a microcontroller for the message synchronization.
