We present an open source stack for the development of custom FPGA boards, primarily but not limited to PCI Express interconnects. Supporting current Linux distributions, the stack consists of a PCI driver, an IP core for a DMA engine, a hardware abstraction library for IO operations, and a buffer management library for efficient handling of data transfers between an application and a FPGA design...
Reconfigurable embedded systems are capable of changing their functionalities by dynamically adding or removing components. This enables hardware/software architectures to adapt to changes in the system environment at run-time which has been proven to be a very useful technique in multimedia applications. This paper proposes a novel methodology to combine hardware and software to a System-on-Programmable-Chip...
The Data Acquisition Backbone Core (DABC) is a new GSI software framework to run data acquisition with distributed event building on high performance Linux clusters. Experimental data input is provided by means of generic Device and Transport interfaces. DABC offers elaborate mechanisms for multiprocessing, buffer management, and dataflow throttling. These are transparently available for all implemented...
Remote controlling of devices or peripherals interfaced with an MCU is essential in couple of applications in Embedded Systems. Web Server is one of the best solutions to do such task if internet is available at such remote locations. The important aspect of this paper is to port an open source Embedded Linux operating system on the FPGA to manage the hardware resources. It is pre-emptible and can...
Along with the rapid development of electronic technology and the constant improvement of user needs, the design of embedded system also faces more challenges. This paper mainly designs an embedded data acquisition system based on FPGA and its structure is as follows. It mainly includes three parts, namely AD, FGPA and embedded platform, FPGA is responsible for collecting, de-noising, accumulating,...
According to the communication and control requirement of multi-channel Control Area Network(CAN) bus by the HLA simulation platform, this paper described a embedded PowerPC system based method of design and implementation of multi-channel CAN communication platform. The corresponding Linux multi-channel CAN device driver has also been developed. This flexible system can connect to different number...
A novel embedded OpenRISC platform was developed with Altera FPGA, its source codes were based on OpenRISC1200 intellectual property (IP) core and uClinux. Five algorithms of video special effects for camera applications were proposed and integrated in the drivers, which included mirror effect, line-scanning effect, diff effect, edge blur effect and noise effect. Moreover, a front-end program interface...
As terminal of through-the wall radar, the main function of display&control system is accomplishing information transfer between the user and the radar: Configure the radar system according to the user, and return detected result in a laconic and effective way finally. Based on all above, the article introduced a new way to construct display&control system, and then relevant software structure...
This paper presents a reconfigurable parallel architecture comprising an FPGA backbone and multiple processing nodes connected in a redundant array architecture and constructed mainly from low-cost commercial components. The reconfigurability of the backbone aids in allowing the system to operate as a fault-tolerant cluster utilising the principle of reliability through redundancy. Although initially...
