The main aim of the TCAM is to perform the search operation using match line (ML). Ternary content addressable memories (TCAMs) are hardware-based parallel lookup tables with bit-level masking capability. They are attractive for applications such as packet forwarding and classification in network routers. Despite the attractive features of TCAMs, high power consumption is one of the most critical challenges faced by TCAM designers. TCAMs are popular because of their searching operation based on the content unlike the RAM cell which does it on the basis of address. The main contribution of this work is testing of ML. The testing of match line was a task which needs to be done to check the searching condition in the TCAM cell. To accomplish this task a new circuitry was added to the existing circuit in order to test the masking condition in a TCAM cell. The work was started from the scratch. First a RAM cell was designed with the goal in mind to be used for the TCAM cell. Various parameters were calculated for the stability of a SRAM cell. The SRAM cell designed was then used in the design of Binary CAMs. After the completion of binary CAM, the cell was modified into the TCAM cell. The additional circuitry added was used to test the working of match line during the search operation of the TCAM cell. Finally, design and testing of a complete TCAM cell is presented.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"45 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133783467","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}

The antenna profile is designed based on microstrip technology using balanced composite right left handed transmission lines (CRLH TL) approach. Conventional LC network representation of the CRLH TL uses cascaded combination of inter digital capacitor (IDC) in series and vias to the ground plane at the stub ends in shunt, whereas in this article the design of full scanning antenna using WBIDC is reported and its performance is compared with conventional IDC based full scanning antenna. Use of WBIDC improves high frequency performance of antenna by reducing undesired resonances at lower frequency end. A simple technique is also used to miniaturize the proposed antenna profile. Dispersion diagram of the balanced CRLH TL based dominant mode leaky wave antenna (LWA) shows the capability of backfire (-90o< e <0o) to broadside (e = 0o) and to endfire (0o< e <90o) scanning. Radiation patterns confirm the full scanability of the antenna and it also shows the designed structure has reduced sidelobes in the endfire radiations. The return loss characteristic of the reported antenna structure shows an increase in the antenna's operational bandwidth. The frequency parameter and performance of the antenna are evaluated by full-wave electromagnetic simulator using Ansoft Designer and these parameters are verified by another full-wave electromagnetic simulator using IE3D.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134301640","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}

Fast spread of wireless data communication systems and the ever increasing demand for faster data rates require quick design, implementation and test of new wireless algorithms for data communications. In this paper we present a novel technique to model the interleaver used in IEEE 802.11a and IEEE 802.11g based WLAN in VHDL using Xilinx ISE. Our proposed technique comprises of finite state machine (FSM) based address generator and FPGA's internal resource based memory. The FSM based approach provides higher operating frequency and better FPGA resource utilization. Use of FPGA's embedded memory offers advantages like reduced access time, lesser occupancy of circuit board and lower power consumption than external memory based techniques. The interleaver memory is modeled using two different types of embedded memory; one with dedicated and the other with distributed memory. Comparative analysis between the two techniques has been made in respect of use of FPGA's internal resources, maximum operating frequency and power consumption. The simulation result obtained using ModelSim XE-III software is also presented.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"193 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121738213","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}
