This module is part of a set of programmable modules, sharing a common communication strategy, that can be combined to realise an Integrated Circuit capable of handling complex video algorithms. The inputs to the module are first selected via a switch matrix and then stored in a two-port dynamic RAM to increase scheduling flexibility. Logic and Arithmetic operations are then performed using an ALU preceded by a set of barrel-shifters. A flexible instruction set is offered by the former, including data-dependent instructions. All sub-blocks are fully programmable using a central program-memory which is loaded via a serial interface. Extensive pipelining and an execution rate of one instruction per clock cycle contribute to a high processing throughput. Parameterized layout generators are used to facilitate ease of modification.","PeriodicalId":187183,"journal":{"name":"ESSCIRC '89: Proceedings of the 15th European Solid-State Circuits Conference","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121884098","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 main feature of the single drivers is a control unit which stabilizes the quiescent current in the output stage at 20mA, while the peak output current is 180mA (T1). The circuit can also be logically configurated to deliver 6 Vpp into a differential load of 60¿ with a quiescent current of 7mA and a data rate of 2.048 Mb/s (CEPT application).

Compared to CMOS, bipolar technology offers better analog features, e.g. offset voltage as well as unique speed advantages. ECL processors, for example, operate at clock rates over 100MHz whereas CMOS processors operate typically at 30MHz. Thus bipolar and CMOS devices form an ideal combination. The only drawback is the higher cost of their fabrication on the same chip. BiCMOS processes are more costly than CMOS processes due to additional masks, processing steps and reduced yield. However, this cost factor is less severe today than in earlier years because of the convergence of bipolar and CMOS technologies. This report describes BiCMOS techniques for high-speed/ high-density circuits for digital as well as analog functions. First the features of MOS and bipolar devices are compared. The different aspects of designing a BiCMOS process are described next. Finally the advantages of the BiCMOS technology for systems applications are demonstrated.","PeriodicalId":187183,"journal":{"name":"ESSCIRC '89: Proceedings of the 15th European Solid-State Circuits Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122071175","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}
