A significant amount of processor power is required to handle packet processing in high speed data networks and taking it to the hardware helps processor to save its energy for other processes. In this study, an Offload Engine IP core that provides the hardware acceleration of UDP/IP protocol stack together with a few other network protocols is introduced. Furthermore, the IP core is equipped with PCI Express (PCIe) interface so as to communicate with applications running on a host PC. Consequently, a processor core deals with only the data processing, while the IP core takes care of the packet processing as per the protocol. The design and implementation of the IP core are verified and tested on an FPGA board; its area utilization and supported features are compared against several competitive designs from the literature. According to these results, the IP core is proved to be a useful one for those network applications that require a hardware-accelerated network protocol stack.

To improve data transmission performance of the data acquisition card, a design of high-speed data transmission system is proposed in the thesis. Using FPGA of programmable logic devices, adopting Verilog HDL of hardware description language, the design of modularization and DMA transmission method is implemented in FPGA. Eventually the design implements the data transmission with high-speed through PCI Express interface. Through simulation and verification based on hardware system, this design is proved to be feasible and can satisfy the performance requirements of data transmission in the high-speed data acquisition card applied in high-speed railway communication. The design also has some value of application and reference for a universal data acquisition card.

Open And Distance Learning

<p>We engage with and respond to the debate raised by this theme issue of the International Review of Research in Open and Distance Learning with a particular question in mind: namely, as universities are using new labor displacing technologies to export degrees to meet the international demand for higher education, how is this influencing – negatively and positively – the workers involved? Contemporary transitions in political and economic globalization are being used to press universities into becoming ‘transnational businesses,’ seemingly driven by a primary concern for marketing educational commodities. The neo-liberal politics driving these currents in universities are increasing the multiple online and offline networks. These local/ global meshworks engage the labors of a small but growing percentage of the world’s population (Singh, 2002, pp. 217-230). Writing this paper at Jilin University in China, we find that many of our academic colleagues and students have limited access to a personal desktop computer, the Internet, and email. They must pay for timed access to their email accounts and for downloading attachments. They do not have access to high-speed data networks. A timer indicates how long it will take to open and send emails. Around us, construction workers are building massive facilities to house the burgeoning on-campus student population. Their offline education is being supplemented – but not replaced by ever-advancing online technologies. </p>
