Design And Implementation Of The Software & Hardware Of A Control Board For The Atm Prototype Switch Onboard

The MPC8280 is an advanced integrated communication processor designed for the telecommunication and network markets. With a high-speed embedded PowerPC core and unparalleled integration of networking & communications peripherals, MPC8280 can be used to design communication and network equipments with high comprehensive performance. The switching onboard using Asynchronous Transfer Mode (ATM) is an important research aspect in satellite communication, thus it is of great value to study ATM onboard switch based on MPC8280.Sponsored by the project named"Prototype of ATM Switching onboard with 10Gbps Large Capacity", this dissertation mainly focuses on studying the design and implementation of the software & hardware of a control board for an ATM prototype switch onboard based on MPC8280. First, it introduces the recent status of the study at home and abroad, as well as relevant research background and significance of the topic to be studied. Then it provides an overview of the MPC8280 processor and its development of Linux embedded system. On the analysis of the hardware design scheme for the switch, it explores the design and implementation of the control board, including the modules of the interface & control, serial port, ethernet port, MPC8280 processor and so on. The design of schematic and Print Circuit Board (PCB), and the hardware debugging for the control board platform have also been completed. The interface & control module implements the Universal Test & Operations PHY Interface (UTOPIA) Level 2 and the interrupts controller. It provides many kinds of control signals which the control board needs as well. Using a Field Programmable Gate Array (FPGA) of Xilinx Spartan-IIE, this dissertation also studies the design, simulation and validation of the interface & control module by VHSIC Hardware Description Language (VHDL). It also addresses the improvement of UTOPIA Level 2 interface and its implementation with a FPGA. The test for the functions of the control board mentioned above has shown their correctness. On the basis of the researching on the development of embedded Linux driver program, it addresses the design of driver for the interface & control module and MPC8280 ATM interface. Finally, the summary of whole dissertation is given and the issues to be studied further are also proposed.
