Computer Architecture, broadly, involves optimizing hardware and software for current and future processing systems. Although there are several other top venues to publish Computer Architecture research, including ASPLOS, HPCA, and MICRO, ISCA (the International Symposium on Computer Architecture) is one of the oldest, longest running, and most prestigious venues for publishing Computer Architecture research. Since 1973, except for 1975, ISCA has been organized annually. Accordingly, this year will be the 50th year of ISCA. Thus, we set out to analyze the past 50 years of ISCA to understand who and what has been driving and innovating computing systems in that timeframe. This analysis is intended to be a celebration of the first 50 years of ISCA. Thus, the scope should be viewed accordingly. Although we took care to practice good data collection and sanitation in our analysis (Section 2), given the long time frame and issues with digital records for early years of the conference, there may be some errors and rounding-off artifacts. Please reach out if you have any corrections and we can update our Arxiv draft to reflect this errata. Finally, while the collected data and analysis highlight several interesting trends, akin to the cautionary comment from the ISCA Hall of Fame website ("A real Hall of Fame should be determined by impact, not paper count."), we want to acknowledge that some of our numbers may only reflect a partial narrative. That said, our exercise still highlights several interesting trends that we think will be insightful to the broader community.

翻译：计算机体系结构，广义上涉及为当前及未来处理系统优化硬件与软件。尽管发表计算机体系结构研究的顶级会议还包括ASPLOS、HPCA和MICRO等，但ISCA（国际计算机体系结构研讨会）是该领域历史最悠久、持续最久且最具声望的学术会议之一。自1973年起（除1975年外），ISCA每年举办一届。因此，今年恰逢ISCA成立50周年。我们系统分析了过去50年的ISCA论文，旨在揭示在此时期内推动和革新计算系统的主要参与者与创新方向。本分析旨在庆祝ISCA的前五十年，其研究范围应作相应理解。尽管我们在分析中尽力遵循完整的数据采集与清洗规范（第2节），但考虑到会议早期年份的电子记录存留问题及时间跨度较长，分析中可能存在若干误差与舍入误差。欢迎指正，我们将更新预印本以收录勘误。最后，虽然所收集的数据与分析揭示了若干有趣趋势，但如ISCA名人堂网站的警示所言（“真正的名人堂应由影响力决定，而非论文数量”），我们承认部分量化指标可能仅反映片面叙事。尽管如此，我们的工作仍揭示了若干值得关注的趋势，相信对学界同仁将有所启发。
