Hydra Operating System 設計에 관한 考察

In the new future, computer system designers are expeted to bring more computer power to more people than is currently feasible. At the same time, it is reasonable for the computer system designers to expect the computer architects to produce hardware structures incorporating system algorithms of greater complexity so that more of the general instructions go to serving the users. In the past. the architect has delivered more computing to the user by constructing bigger and faster central processors, possibly connecting two or three CPUs together. This approach has its limitations, in cost, complexity and reliability. In this paper, we first briefly discuss the hardware environment on which Hydra was implemented, then discuss the philosophy on which the system is based, and finally exhibit the protection mechanism.
