C.ai(P.L.*) -- An L* Processor for C.ai

摘要

The results of a preliminary design study for a specialized language processor (P.l) for L* are presented. The objective of the study is to give an example of a specialized processor for C.ai. The L* processor is to run 20-30 simultaneous L* users with very large address spaces at a speed improvement of better than 10 times a typical PDP-10 L* system. Its cost should be low relative to the memory resources of C.ai. The design presented is that of an L* central processor (Pc.L*) with a low-level instruction set (about the level of typical microcode). Pc.L* is time-shared by a mini-computer that sits to the side, so that each L* user sees himself as running on a base L* processor. User contexts are switched by swapping processor status information in Pc.L*. (Author)
