상위 레벨 합성을 위한 저 전력 스케줄링 및 자원할당 알고리즘
신무경,인치호,Sin, Mu-Kyoung,Lin, Chi-Ho 한국정보처리학회 2001 정보처리학회논문지 A Vol.8 No.3
본 논문은 상위 레벨 합성 과정에서 DSP와 같은 회로를 대상으로 전력소모를 최소로 하는 스케줄링 및 자원할당 알고리즘을 제안한다. 본 논문에서는 스케줄링 시의 저 전력 설계는 리스트 스케줄링 방법을 이용한다. 그리고 자원공유를 통하여 자원할당 시 입력을 재 사용할 수 있는 가능성을 증가시킨다. 스케줄링 후 자원할당 방법은 두 입력 사이의 평균 해밍 거리와 교환동작을 계산한 결과값을 고려하여 전력 함수를 이용한다. 먼저 두 연산자 사이의 평균 해밍 거리를 계산한 후 입력 값에 대한 교환동작을 구하며, 입력 값의 비트 패턴을 이용하여 전력 값을 구한다. 자원 할당 과정은 제어 단계를 한 단계 씩 증가시키면서 각 제어 단계에서 할당 될 수 있는 모든 경우들에 대하여 평균 해밍 거리가 가장 적고 전력 함수에 의한 전력이 가장 적게 소비되는 연산자를 할당한다. 기존 방법과 비교했을 때 그 수행속도는 사용하는 연산자의 개수와 최다 제어 단계에 따라서 빨라진다. 그리고 소모하는 전력이 6%에서 8%까지 감소효과가 있었다. This paper proposes a low power resource allocation and scheduling algorithm that minimized power consumption such as DSP circuit in high-level synthesis process. In this paper, we have used list-scheduling method for low power design in scheduling step. Also, it increase possibility to reuse input through resource sharing when assign resource. After scheduling, the resources allocation uses the power function in consideration of the result of calculating average hamming distances and switching activity between two input. First, it obtain switching activity about input value after calculate average hamming distances between two operator and find power value make use of bit pattern of the input value. Resource allocation process assign operator to minimize average hamming distance and power dissipation on all occasions which is allocated at each control step according to increase control step. As comparing the existed method, the execution time becomes fast according to number of operator and be most numberous control step. And in case of power that consume, there is decrease effect from 6% to 8% to be small.

To today with the acceleration due to the preference actual condition of high-class energy national income level it is together improving. It follows hereupon and it is convenient and the neat heat source is increasing a tendency where it is. It investigates the government offices building in commerce portion from the research which it sees and from the draft it analyzes a coat dosage. And comparison it analyzes the movable present condition of thread use dosage and the freezer. It presents the improvement direction against enemy conditions heat source equipment selecting. Also, currently it produces the dosage of heat source equipment and application it tries. The result, the various safety rate and the premium rate which it uses universally are considered above thread using. The reappraisal for enemy conditions heat source equipment selecting which it follows hereupon is necessary.

Background and Objectives : Interstitial cells of Cajal(ICC) are the pacemakers in gastrointestinal tract that modulates gastrointestinal motiliey and these cells also transmit neural input from enteric nerves to smooth muscles. Recent work on tissues from patients with motility disorders that suggest that loss or defect in ICC could be related to pathophysiology in human and animal models. Immunolabelling of ICC in intestinal wall is recently developed by using specific marker, anti-c-kit antibody. Immunohistochemistry was done for ICC network in attempt to provide a morphological basis for the mechanism regulating gastrointestinal motility Methods : Cryosection was done, and whole-mount preparations of mouse stomach, gastrointestinal tract were immunolabelled using the anti-c-Kit. Immunolabelled ICC networks were observed under a confocal laser scanning microscopy. Results : According to three dimensional reconstruction study, we found that the c-Kit-positive celluar networks were widely distributed in the gastrointestinal muscle (1) circular muscle layer(IC-IM), (2) myenteric plexus(IC-MY), (3) deep muscular plexus(IC-DMP) in ileum, (4) submucosal plexus(IC-SMP) and longitudinal muscle layer(IC-LM) in colon. Conclusion : The characteristic profiles of ICC celluar networks provide a morphological basis upon the mechanism regulating gastrointestinal motility. Additional studies for the enteric nerves-ICC interaction are need to evaluate the detailed roles of Icc in gastrointestinal tract.
