Otherwise, any encountered compilation and simulation obstacles might hinder his/her synthesis project. Finally the observation is made that the synthesis engineer must also rely on his/her digital background to order to write VHDL models that will synthesize into optimum hardware.","PeriodicalId":307095,"journal":{"name":"Proceedings of Eighth International Application Specific Integrated Circuits Conference","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122446443","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 parameters for system performance evaluation are noise, resolution, and modulation transfer function. Currently, to develop a digital signal processing ASIC is still a major effort in the CCD camera development.
