This paper describes two humanoid robots developed in the Humanoid Robotics Institute, Waseda University. Hadaly-2 is intended to realize information interaction with humans by integrating environmental recognition with vision, conversation capability (voice recognition, voice synthesis), and gesture behaviors. It also possesses physical interaction(More)
This paper evaluates the performance of job scheduling schemes for pure space sharing among rigid jobs. Conventional job scheduling schemes for the pure space sharing among rigid jobs have been achieved by First Come First Served (FCFS). However, FCFS has a drawback such that it can not utilize processors e ciently. This paper evaluates the performance of(More)
This paper proposes a multi-grain paraUelizing compilation scheme for Fortran programs. The scheme hierarchically exploits parallelism among coarse grain tasks, such as, loops, subroutines or basic blocks, among medium grain tasks like loop iterations and among near fine grain tasks like statements. Parallelism among the coarse grain tasks called the(More)
This paper proposes a compilation scheme for parallel processing of near fine grain tasks, each of which consists of several instructions or a statement, on a multiprocessor system called OSCAR (Optimally Scheduled Advanced Multiprocessor). The scheme allows us to minimize synchronization and data transfer overheads and to optimally use registers of each(More)
In most cases, the scheduling problem for the multiprocessor system is NPor strong NP-hard. For this problem, we have already proposed a practical optimization algorithm DF/IHS (Depth First/Implicit Heuristic Search), which combines the list-scheduling algorithm and the depth-first search, for the minimum parallel processing time multiprocessors scheduling(More)
