A Compatible Variables Scheduling Algorithm for Register Allocation in Microprogram

이상정,임인칠,Lee, Sang-Jeong,Lim, In-Chil The Institute of Electronics and Information Engin 1987 전자공학회논문지 Vol.24 No.2

This paper proposes a compatible variables scheduling algorithm, which is the process to pack variables into same register without modifying program semantics, for efficient register allocation of microprogram. The algorithm constructs T-V matrix, obtains incompatible variable set and scheduling priority, and schedules compatible groups. By this algorithm, the number of compatible groups can be minimized. The algorithm was implemented with C language on VAX-11/780 computer. By applying the algorithm to practical microprograms, the effectiveness of the algorithm is verified.

디자인보호법의 발전방향에 관한 소고

이상정 ( Lee Sang Jeong ) 한국지식재산연구원 2005 지식재산논단 Vol.2 No.2

This is the study about how to revise our current design act. Our current design act consists of the substantial examination system(SES) and non-substantial examination system(NSES). From 1998 we have a dual system. We introduced the NSES for the short-term life cycled products. The rights conferred through SES and NSES are same: monopolistic right. So many designs without qualification have exclusive rights. Those are hindering the development of design industry. It must be changed. This paper propose the abolishment of dual system. But it does not mean to turn back to the pre-1998 system. It is out of date and inefficient for all designs to be examined substantially to be registered. Even though all designs should be registered to gain the design right, it need not be examined whether it fulfills the substantial requirement. If only formal and procedural requirements are fulfilled, it could be registered. But before the right-h이der enforce the right it must be undergone substantial examination. So substantial examination is pre-requite for the enforcement. It must be based on the request of right holder. The time of the request for the examination must be limited like patent law. The nature of right from registration is monopolistic and the right has a block effect. This paper opposed the two-tier system: opposition to the adoption of unregistered design right system(UDRS). The major problem is the uncertainty. As [Australian Law Reform Report] says a manufacturer may be uncertain whether his or her product is so similar that it will be taken to be a copy. And in a sense we have already UDRS. It is in the Unfair Competition Law and Copyright Law. Not common-place design is protected from so-called dead copy by Unfair Competition Law, and copyright law protect some designs from copying. So there is no need to introduce the UDRS into the Design Protection Act itself.

값 예측 오류를 위한 순차적이고 선택적인 복구 방식

이상정(Sang-Jeong Lee),전병찬(Byung-Chan Jeon) 한국정보과학회 2004 정보과학회논문지 : 시스템 및 이론 Vol.31 No.1·2

고성능 슈퍼스칼라 프로세서에서 값 예측(value prediction) 방식은 명령의 결과 값을 미리 예측하고, 이 후 데이타 종속 관계가 있는 명령들에게 값을 조기에 공급함으로써 이들 명령들을 모험적으로 실행하여 성능을 향상시키는 방식이다. 값 예측으로 성능을 향상시키기 위해서는 예측 실패 시에 효율적으로 복구하는 과정이 필수적이다. 본 논문에서는 값 예측 실패 시에 잘못 예측된 값을 사용하여 모험적으로 수행된 명령들만을 순차적으로 취소하고 복구한 후에 재이슈하는 값 예측 실패 복구 메커니즘(value misprediction recovery mechanism)을 제안한다. 제안된 복구 방식은 한번에 모든 종속명령들을 검색하지 않음으로써 파이프라인을 정지시키지 않는다. 즉, 파이프라인이 진행되는 순서에 따라 순차적으로 값 예측이 틀린 종속명령만을 선택적으로 취소하고 재이슈하여 불필요한 취소와 재이슈를 줄임으로써 값 예측 실패 시에 손실을 줄인다. Value prediction is a technique to obtain performance gains by supplying earlier source values of its data dependent instructions using predicted value of a instruction. To fully exploit the potential of value speculation, however, the efficient recovery mechanism is necessary in case of value misprediction. In this paper, we propose a sequential and selective recovery mechanism for value misprediction. It searches data dependency chain of the mispredicted instruction sequentially without pipeline stalls and adverse impact on clock cycle time. In our scheme, only the dependent instructions on the predicted instruction is selectively squashed and reissued in case of value misprediction.

In order to identify dynamic behavior of complex structure as nuclear reactor, vibration analysis is mostly conducted as using finite element method (FEM). If the structure is complicated, high computational cost and time is demanded at vibration analysis using FEM. After model reduction is fulfilled with using dynamic substructuring method, it is objective to decrease the computational cost and time at vibration analysis of complex structures in this study. With applying selecting method of mater degree of freedom (MDOF) whose validity was identified in previous study, accuracy of vibration analysis is guaranteed. We apply the method to APR 1400 nuclear reactor internals which are one of complex structures. Because the result of application shows that vibration analysis data from dynamic substructuring method are well matched with original method, we confirm the effect of Vibration analysis using dynamic substructuring method.

본 논문에서는 멀티코아 프로세서 상에서 프로세서와 메모리를 집중적으로 사용하는 다양한 워크로드들에 대한 온도특성을 연구한다. 일반적으로 프로세서의 온도관리를 위한 측정 지표로 평균온도와 온도범위 보다는 온도변화의 정도가 더 중요하다. 따라서 본 논문에서는 프로그램 실행 중에 온도변화를 분석하고, 워크로드의 온도변화의 정도를 정량화하는 측정 지표를 제안한다. 제안된 온도변화 측정 지표를 사용하여 인텔 Core 2 Duo 프로세서 상의 SPEC CPU2006 벤치마크들에 대해 쿨링 조건 및 클럭 주파수를 변경해 가며 온도변화를 분석한다. 분석 결과, 각 벤치마크 프로그램에 따라 서로 다른 유형의 온도 변화를 보였다. 이러한 온도변화는 쿨링 조건과 동작 클럭 주파수 및 멀티프로그래밍 워크로드에 영향을 받았다. 또한 코아들 사이의 공간적 위치에 따라서도 다른 온도 변화 특성을 보였다. 본 논문에서 제안된 온도변화 측정 지표와 연구 분석된 결과들은 향후 멀티코아 온도관리를 위한 연구에 활용하면 효과적인 온도관리가 기대된다. This paper studies thermal characteristics of a mix of CPU-intensive and memory-intensive application workloads on a multi-core processor. Especially, we focus on thermal variations during program execution because thermal variations are more critical than average temperatures and their ranges for thermal management. New metrics are proposed to quantify such thermal variations for a workload. We study the thermal variations using SPEC CPU2006 benchmarks with varying cooling conditions and frequencies on an Intel Core 2 Duo processor. The results show that applications have distinct thermal variations characteristics. Such variations are affected by cooling conditions,operating frequencies and multiprogramming workload. Also, there are distinct spatial thermal variations between cores. Our new metrics and their results from this study provide useful insight for future research on multi-core thermal management.

퍼블리시티권에 관한 소고

이상정 ( Sang Jeong Lee ) 아세아여성법학연구소 2001 아세아여성법학 Vol.4 No.-

The Right of Publicity prevents the unauthorized commercial use of an individual`s name, likeness, or other recognizable aspects of one`s persona. It gives an individual the exclusive right to license the use of their identity for commercial promotion. In the United States, the Right of Publicity is first recognized in Haelan Case and now largely protected by state common or statutory law. In Korea the Right of Publicity is recognized and mainly protected through the law of tort competition law and Copyright law may apply to the infringement of the Right Publicity. This Paper compose of 5 chapter : 1) Introduction, 2) The Right, 3) The subject and object of the right, 4) Remedies, 5) Conclusion. This paper contains; (1) whether the Right of Publicity is assignable and descendible(inheritable). (2) who has the Right of Publicity: Does only famous person have the Right of Publicity? (3) the scope of the Right of Publicity; Is {Lim, Ggug-Jeong court of Korea} and {Vanna Wbite court of US} right? (4) whether Injunctive Relief is available in Korea Legal System. As to topic (1) I think it`s not assignable but descendible. So general succession is admitted, but singular succession is not permitted. As to topic (2) I think that every (natural and legal) person who has the power to attract the public has the Right of Publicity. As to topic (3) I do not agree with 2 decisions. Both of them go too far. As to topic (4) I think that injunctive relief is available in Korea. As conclusion I suggest it`s more preferable to legislate on the Right of Publicity.

제조물책임법과 개발위험의 항변

  More than 5 years have passed since our Product Liability Act was enforced. The enactment of Product Liability Act means that the liability system based on the negligence shift to the liability system based on the defect. So many consumer supposed that there was the drastic change in the area of PL. But in reality there is little change. It"s because design defects and warning defects are primarily based on the negligence of producer. And even in the area of manufacturing defects there is little change. Before the enforcement of new act the producer was apt to be liable to the defects he made regardless of his fault or negligence. And Presumption of negligence was applied in many cases.<BR>  One of the consumer"s disappointments is the adoption of the "Development Risk" defense(the state-of-the-art defense). It"s prescribed in the § 4① ⅱ of our act. That is as follows:<BR>  Article 4 (Exemptions) ① In cases where Article 3 applies. the manufacturer. etc. shall not be liable as a result of Article 3 if he proves;<BR>  (1.)<BR>  2. that the state of scientific or technical knowledge at the time when the manufacturer, etc. delivered the product was not such as to enable the existence of the defect in the product to be discovered:<BR>  But I think that the adoption of the "Development Risk" defense is not adequate even though many industrial nations accept the state-of-the-art defense.<BR>  First of all It"s nearly impossible to find out "the state of scientific or technical knowledge at the time when the manufacturer. etc. delivered the product". Because Scientific knowability refers not to what in fact was known at the time. but to what could have been known at the time.<BR>  And the adoption of the "Development Risk" defense means that the human is the means of the development of science or technology. So "Development Risk" defense in our act must be deleted. But for the compromise of innovation and safety. this paper proposed. the compensation may be reduced when the producer observed carefully. warned the hazards and recalled them after delivering the products.<BR>  This paper ends with the phrases which were appeared in the "Beshada v. Johns-Manville Products Corp" judgement :<BR>  The concept of knowability is complicated further by the fact---that the level of investment in safety research by manufacturers is one determinant of the state-of-the-art at any given time.<BR>  By imposing on manufacturers the costs of failure to discover hazards, we create an incentive for them to invest more actively in safety research.
