| Research Abstract |
In order to support high-level language programming effectively, obviously the language system must be organized as an elaborate tool set, although the exeution speed of the tool cannot be ignored. This is especially important when a low speed tool such as interpreter is used. This situation can be easily changed by the use of hardware technology which has been drastically developed for the past decade. Rather complex algorithm can be easily implemented in a single chip. This research is targeted to seek for systematic approaches to transform software based algorithms into hardwared one. When drastic efficiency should be expected, however ; usual simple minded approach is not so effective ; for example, a microprogram implementation of software algorithm may obtain 10 times performance ; however, when a hardware oriented approach is found, sometimes we obtain more than 100 times performance. In our project, a sillicon compiler is used to design a LSI chip and evaluate its perfoemance. As applications we used two language interpreters : PL/0 and Prolog, and made prototype chip designs for these. As a result, we got several valuable experiences and design measures of VLSI realization of language system, and preparation of more actual design of real chips.
