The motivating application is the localization and control of epileptic seizures where hitherto published results shown the effectiveness of exploiting Generalized Partial Directed Coherence to quantify and analyse connectivity and interaction of brain structures. To speed up GPDC computations we develop first, a parallelizing strategy leading to the high performance scalable architecture and second, a low-complexity fixed-point reciprocal square root module. We show that a real-time computation is feasible at a speed of 0.027ms for 16 channels and 1.637ms for 128 channels. Furthermore, the implementation results on Xilinx 7A35T, KC705, VC707, KU115 show that the power requirements are quite modest and allow for the embedded application of the engine.","PeriodicalId":215448,"journal":{"name":"2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124899904","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}

Especially, the 10G transmitter designs of the office equipment (OLT), the terminals and the network units (ONTs and ONUs) become quite demanding because of the real-time requirements for preparing a frame. The current paper introduces a three layer architecture, scalable with respect to the bandwidth and suitable to realize the transmitter of the XG-PON OLT/ONT/ONU elements. The architecture's upper layer decides what data packets will be transmitted. The second layer's microsequencer commands the lowest layer's modules, which produce and locally store all the data packets to be transmitted. The three layer approach allows the architecture to be configured and organized as either an OLT transmitter or an ONU/ONT transmitter; and to be scalable and perform the functions of the OLT at 10 Gbps and those of an ONU/ONT at 2.5 Gbps. The implementation of a XG-PON ONU transmitter on Xilinx Virtex7 verifies the approach.","PeriodicalId":215448,"journal":{"name":"2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123569276","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}

Bus topologies and Networks-on-Chip (NoCs) are the main approaches used to implement on-chip communication. The interconnect fabric enables resource sharing by Time and/or Space Division Multiple Access (T/SDMA) techniques. Code Division Multiple Access (CDMA) has been proposed to enable resource sharing in on-chip interconnects where each data bit is spread by a unique orthogonal spreading code of length N. Unlike T/SDMA, in wireless CDMA, the communication channel capacity can be increased by overcoming the Multiple Access Interference (MAI) problem. In response, we present two overload CDMA interconnect (OCI) bus architectures, namely TDMA-OCI (T-OCI) and Parallel-OCI (P-OCI) to increase the classical CDMA interconnect capacity. We implement and validate the T-OCI and P-OCI bus topologies on the Xilinx Artix-7 AC701 kit. We compare the basic SDMA, TDMA, and CDMA buses and evaluate the OCI buses in terms of the resource utilization and bus bandwidth. The results show that the T-OCI achieve 100% higher bus capacity, 31% less resource utilization compared to the conventional CDMA bus topology. The P-OCI bus provides N times higher bus bandwidth compared to the T-OCI bus at the expense of increased resource utilization.","PeriodicalId":215448,"journal":{"name":"2015 IEEE International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130507666","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}

Using this technique, we will show how the offset is reduced due to the nonlinearities of the integrator circuit and of the multiplying core, principally.
