I guess I'd much rather hear what others have to say. On the other hand, I do want to report that it was a privilege to take my turn as your Workshop Chairman, and I wish Gerry and others success in the years ahead with Micro n, as we continue to increase n. As I did at the Workshop itself, I want to again express my thanks to Rich Belgard and Wen-mei Hwu for taking on such a large part of the job. In the case of Rich, it was yet another Micro n that he put his own personal good stamp on. In the case of Wen-mei, it was the kind of thorough first rate job that I have become used to seeing him do. I eagerly look forward to the Micro n Workshop that we convince him to lead as General Chairman. For those of you concerned about such things, we made a bunch of money, enough to subsidize mailing the Proceedings to the SigMI-CRO membership and still report a substantial profit to our co-sponsors, IEEE and ACM. Now, we look forward to Micro 22. Gerry Johnson has carved out an exciting first for us in organizing it in Dublin. The interest in Microprogramming and Microarchitecture in general and the quality of the technical interaction at the Workshop in particular continue to grow. In addition, the wonder of the country , from Galway to Donegal to the Antrim coast, is not to be missed. So, for both professional technical reasons and for personal enrichment reasons, I encourage you to plan on spending part of August in Dublin at Micro 22. Finally, I would urge the subsequent Workshop Chairmen to keep in mind the sentiment of the attendees at Micro 21, as expressed in our much-too-long meeting on Thursday night of the Workshop , that we wish to continue the co-sponsorship of the workshop by both professional societies (IEEE and ACM). As was pointed out so eloquently by me, each society contributes to our professional needs in different and complementary ways, and we are fortunate to be able to enjoy both and not have to choose between the two.","PeriodicalId":138968,"journal":{"name":"ACM Sigmicro Newsletter","volume":"288 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132119659","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 paper clarifies the issue of loading instructions into the instruction queue and evaluates the resulting performance due to different schemes. paths are identified in the complicated UNIX programs so that trace scheduling can be effectively applied. Experimental results are provided for ten UNIX system and CAD programs which all exhibit complicated control structure. This is the first paper to address the issue of applying trace scheduling to complicated programs. The work is critical to adapting trace scheduling to RISC's and other upcoming pipelined, parallel mlcroarchltectures. Research The CMOS 370 has some Control Store on chip and some off. A small on-chip Control Store holds the first two microwords of each microsequence (target of conditional branches). A close look reveals that the two-level Control Store structure can be viewed as a programmer managed target instruction buffer. This structure makes it possible to access one microinstruction from a (mostly off-chip) large Control store every cycle while achieving a short cycle time. Efficient trapping is proposed to support efficient instruction emulation in processors with hardwired control. This makes the issue of instruction set design relatively independent of the implementation (hardwired or microprogrammed). • \"Multiple Instruction Issue and Single-Chip Processors,\" A. Pleszkun and G. Sohi, U. of Wisconsin-Madison. Sometimes issuing multiple instructions is not a win. It would be interesting to experiment on the effect of compilation support (trace scheduling, register allocation, etc.) on the instruction issue rate. Comparing the results presented in this paper and those presented by the VLIW team, compilation support seems to be critical for issuing multiple instructions per cycle. The paper discusses the dilemma due to the interdependence between data routing and code scheduling in ASIC code generation. This issue corresponds closely to the one regarding the code scheduling and register allocation for pipelined and/or wide instruction architectures. The trend is to consider both factors together during code generation. The dynamic reconfigurability is a very interesting feature of the proposed ASIC paradigm. However, the slow prototype makes one wonder if a simple microprocessor can be programmed to achieve the same performance for the target applications. • \"Implementing a Prolog Machine with Multiple Functional Units,\" A. Singhal and Y. Patt, U. C. Berkeley.
