According to the current state of the midpoint under different types of vector action, a self-adaptive distribution factor method is proposed, which can self-adjust according to the potential difference of the midpoint, and the expected effect is obtained in the simulation.","PeriodicalId":127121,"journal":{"name":"2018 IEEE 2nd International Conference on Circuits, System and Simulation (ICCSS)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116576027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to suppress the non-linearity caused by inter-stage gain error due to insufficient amplifier gain, a new dithering technique is employed on the residual transfer function. In addition, the comparators in all stages are trimmed digitally to minimize their offset and further improve the linearity. The measured signal-to-noise ratio (SNR) and spurious free dynamic range (SFDR) are 67 dB and 88 dB after calibration at 350 MHz input signal.

This article innovatively applies it to the train ticket market, and introduces such a mechanism at the interface of the ticketing system to prevent the system from being attacked. Based on the background of China's internet train ticketing system, this paper analyzes the internal and external attacks on the system, designs an algorithm based on proof-of-work, and expands according to the geographical location, credit rating, and system load based on different problems. However, there is a big difference in CPU performance between different computer devices, leading to the difficulty for some users with insufficient computing power to buy tickets. The time difference in accessing the memory has the same algorithm complexity. Therefore, the algorithm that was previously limited to the CPU needs to be adjusted to Memory-bound algorithms. The results show that the application of memory-bound proof-of-work algorithm in the ticket purchasing market can better balance the difficulty of buying tickets and resist external attacks, so as to satisfy most people's ticket requirements and ease the pressure of Spring Festival travel.","PeriodicalId":127121,"journal":{"name":"2018 IEEE 2nd International Conference on Circuits, System and Simulation (ICCSS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114443393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we analyze three different schemes used for the multicast queues and design a queue manager for CIOQ switches, which can support independent management of multicast queues. The queue manager designed separates unicast queues and multicast queues, thus can provide different QoS (quality of service) for these two queues, and then allocate bandwidth more flexibly. In addition, we use link list instead of independent FIFO in the design in order to save resources. Moreover, the throughput of the system will be improved due to the controlled traffic. The whole design is realized with Verilog HDL, simulated with Modelsim SE 10.2c in Xilinx xc6vlx240t FPGA.
