An access network controller SLEIGH : On SoC technology

In this paper, an access network controller for ADSL (Asymmetric Digital Subscriber Line) access is described. It consists of a Vr4120 MPU core, a system controller, an Ethernet controller, an ATM (Asynchronous Transfer Mode) cell processor, a USB (Universal Serial Interface) controller and other blocks. This controller, along with ADSL PHY devices, can provide a total solution for ADSL modem and ADSL router.
