The performance of this prototype is compared with that of enhanced architectures configured with special wafer types to accelerate neural network operations. The design emphasizes the synergy between neural processing functions and the 3D WSI architecture and packaging. Detailed microcode emulations are used to access the impact of different algorithms and architecture modifications.

Because GaAs parts do not yield at the high rates of more mature silicon technology devices, it is presently infeasible to build monolithic wafer scale integration (WSI) with GaAs technology. A hybrid wafer scale integration (HWSI) approach has been developed to overcome the limits of monolithic approaches, including the ability to provide for multichip module (MCM) process optimizations serving low IR loss requirements for power delivery, and use of overlay interconnect, first placing the chip into a structure for the most advantageous thermal management.<<ETX>>","PeriodicalId":377227,"journal":{"name":"1993 Proceedings Fifth Annual IEEE International Conference on Wafer Scale Integration","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126039086","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}

It is found that the large physical dimensions of a wafer scale system require that the signal interconnections be treated as transmission lines with finite delays in order to provide an accurate simulation of the signal wave shapes and timing. When clock distributions networks are compared, it is found that for a given power budget a tradeoff between delay and skew can be made. If a total power budget is established for the clock distribution network, then the five methods can be compared as to signal propagation delays and skew.<<ETX>>","PeriodicalId":377227,"journal":{"name":"1993 Proceedings Fifth Annual IEEE International Conference on Wafer Scale Integration","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131064418","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}
