Abstract

This paper presents a novel system architecture applicable to highperformance and flexible transport data processing which includes complex protocol operation and a network control algorithm. We developed a new tightly coupled Field Programmable Gate Army (FPGA) and hIicroProc&ng Unit (MPU) system named Yet Another Re-Definable System (YARDS). It comprises three programmable devices which equate to high flexibility. These devices are the RISC-type MPU with memories, programmable inter-connection devices, and FPGAs. Using these, this system supports various styles Of coupling Ween the FPGAs and the MPU which are suitable for constructing transport data processing. In this paper, two applications of the system in the telecommunications field are given. One is an Operation, Administration, and Management (OAM) cell operations on an Asynchronous Transfer Mode (ATM) network The other is a dynamic recontiguration protocol enables the update or change of the functions of the transport data processing system on-line. This is the first approach applying the FPGAMPU hybrid system to the telecommunications field.
