Development and Integration of Graphical User Interface (GUI) with JUNGO Device Drivers for PCI Express Interface

Abstract

High-bandwidth Video Bus is a video interface protocol defined for high bandwidth, low latency, and uncompressed digital video transmission in avionics systems. This protocol is used for interfacing aircraft system(s) into the cockpit display. Current day technology realizes the systems or Line Replaceable Units (LRU) using Field-Programmable Gate Array (FPGA) based Intellectual Property (IP) Cores for communication between two systems. However, these communication protocols are realized using FPGA and as part of development, the Peripheral Component Interconnect (PCI) express based FPGA embedded modules are used for realization. These embedded modules will be interfaced to the host computers to transmit the data as similar to the communication on aircraft for real LRU. Hence host computers need to be integrated with required GUI application which shall communicate with PCI express bus connecting the FPGA based embedded module. This paper describes the development of the GUI application program for PCI express data simulator using device drivers generated by JUNGO (WinDriver) tool for memory read/write transaction(s). The paper also presents the integration, testing and data transfer for discrete and continuous data over PCI express from the host machine to the embedded FPGA-based module.
