A new set of features and functionality is being brought to this successful architecture by two new device families: MAX 9000 and MAX 7000s. In addition to the popular features offered by the existing MAX 7000 devices, the primary enhancements that these two families provide are: In-System Programmability (ISP) and JTAG Boundary-Scan Test capability. MAX 7000s family includes device densities up to 5000 usable gates and are completely pin, function, and programming file compatible with existing MAX 7000 and MAX 7000E devices. MAX 9OOO devices range from 6,000 to 12,000 usable gates and are therefore the highest density Erasable Programmable Logic Devices (EPLDs) offering ISP capability. In addition to ISP and JTAG, MAX 9OOO and MAX 7000s devices include a host of other new features; these will be described in this session as well.","PeriodicalId":177121,"journal":{"name":"Proceedings of WESCON'95","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131657042","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}

This is best demonstrated by the popular 16V8 and 22V10 devices.

VPSK is BPSK modulation with the data encoded prior to transmission by Single Sideband FM-SC. This results in an Wq value that is theoretically better than that for QPSK, even though the occupied bandwidth is oniy 1/5 as large. Eb/n values of 14 dB for 10-6 BER are being obtained in the field at 10 bits/Hz compression.

The area of CAD which studies the design of the hardware and software components of embedded systems is called hardware-software co-design. Embedded computing systems must fresuently meet hard real-time deadlines as well as soft performance goals. Since embedded system designers control what software will be executed on the hardware platform, they have a great deal of freedom to jointly optimize the hardware and software designs to meet performance and cost goals.

This solution provides for clear and reliable transport of information between users. At the center of these systems are embedded processors which allow for access to nearly all SONET network information. Additionally, some processors incorporate communications controllers for transfer of SONET Data Communication Channel (DCC) information as well as a UART for data transfers between the host and target systems. Contained on board with the processor are several firmware routines stored in memory that are executed by the processor when instructed by the host system. Performance monitoring, error detection, and alarm conditions are all reported through embedded processor access. This paper gives a brief SONET overview and discusses embedded processor system components, embedded processor functions, firmware development, and design considerations for embedded SONET system applications. Along with describing these areas, a case study of a SONET evaluation system using a Motorola MC68302 embedded processor is provided.","PeriodicalId":177121,"journal":{"name":"Proceedings of WESCON'95","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121475239","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 combined technology is based on modified Neufuz (‘71, ‘21, ‘31) using recurrent neural networks. The recurrent information of neural net is directly mapped to a new type of fuzzy logic, called “recurrent” fuzzy logic. Recurrency preserves temporal information and yields superior performance for context dependent applications like handwriting, pattem and speech recognition. It also reduces the convergence time to learn fuzzy logic rules and membership functions. We have used recurrent fuzzy logic approach to solve several problems associated with speech recognition. Simulations show good improvements in accuracx speed of learning and speaker variability for isolated word recognition.","PeriodicalId":177121,"journal":{"name":"Proceedings of WESCON'95","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130082204","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}
