Data Communication

SDLC Protocol Controller	The controller that handles SDLC protocol which is a subset of HDLC protocol. It interfaces with the host using generic bus and several interrupt lines. The core is also available with AMBA® APB interface.
HDLC Protocol Controller	A hardware implementation of two full-duplex HDLC channels. It integrates SDLC with the hardware support for LAPB/LAPD protocols (auto I and S frame handling). It interfaces with the microprocessor through a generic bus.
HDLC Connectivity Platform	The HDLC Connectivity Platform is an integrated solution that significantly shortens the time necessary for development of an 8-bit SoC enhanced with advanced data communication capabilities.

These cores have been successfully prototyped in Altera Flex chips and/or Xilinx Virtex.
