Thesis (MScEng)--Stellenbosch University, 2002. / ENGLISH ABSTRACT: This report describes the development of a Java Bytecode Compiler (JBC) for the 8051 micro-controller. Bytecodes are found in the class file generated when a Java source file is compiled with the java compiler (javac). On Java platforms, the Java Virtual Machine (JVM) interprets and executes the bytecodes. Currently existing Java platforms do not support programming the 8051 using Java. As an 8-bit micro-controller with only 64 KB of total memory, the 8051's word size and memory is too limited to implement a NM. Moreover, full applications of the 8051 require that it handles hardware interrupts and access 110 ports and special registers. This thesis proposes a JBC to compile the standard bytecodes found in the class file and generate equivalent assembly code that can run on the 8051. The JBC was tested on the 8051 compatible AT89C52*44 micro-controller with a program that simulates an irrigation controller. The code generated by the JBC executes correctly but is large in size and runs slower than code of a program written in assembly. Conclusions drawn are that the JBC can be used to compile Java programs intended for the 8051 and its family of micro-controllers. In particular, it is especially a good tool for people who prefer Java to other languages. The JBC is suitable for smaller programs that do not have efficiency as a major requirement. / AFRIKAANSE OPSOMMING: Hierdie tesis beskryf die ontwikkeling van 'n Java "Bytecode" samesteller (Java Bytecode Compiler, JBC) vir die 8051 mikro beheerder argitektuur. "Bytecodes" is die produk van die standaard Java samesteller "javac" en word deur 'n platform spesifieke Java Virtuele Masjien gelees en uitgevoer. Geen NM is huidig beskikbaar vir die 8051 argitektuur nie. Die gekose 8-bis 8051 mikro beheerder het 'n beperkte interne geheue van 64kB. Hierdie beperking maak dit nie geskik vir 'n IVM nie. Daar moet ook voorsiening gemaak word om hardeware onderbrekings te hantering en te kan kommunikeer met die poorte en spesiale registers van die mikro beheerder. JBC word ontwikkel wat die standaard "Bytecode" kompileer na geskikte masjien kode wat dan op die mikro beheerder gebruik kan word. Die JBC is ontwikkel en toets en 'n eenvoudige besproeiing program is geskryf om op 'n Atmel AT89C52*44 te loop. Die kode werk goed maar is nog nie geoptimeer nie en loop onnodig stadig. Optimerings metodes word aanbeveel en bespreek. Die gevolgtrekking is dat die huidige JBC kan gebruik word om Java kode te skryfvir die 8051 beheerder. Dit maak die hardeware platform nou beskikbaar aan Java programmeerders. Daar moet wel gelet word dat die JBC op die oomblik net geskik is vir klein programme en waar spoed nie die primêre vereiste is nie.

A transformação entre linguagens, ou entre diferentes formatos de uma mesma linguagem, é um assunto que desperta interesse há vários anos e desta forma alguns trabalhos tem surgido para tentar automatizar o processo de transformação entre notações diferentes. Este trabalho descreve as Gramáticas Transformacionais empregados para descrever as transformag6es necessárias para converter uma notação em uma linguagem fonte (LF) para uma notação equivalente em uma linguagem objeto (LO). Nesta Gramática é embutido o conceito de Gramáticas de Atributos, criando assim as Gramáticas Transformacionais com Atributos (GTAs). Para validação das GTAs é apresentado um protótipo de ferramenta transformacional, que gera um tradutor, de LF para LO, a partir da descrição da gramática da LF e das regras de transformações para a LO. Tanto a LF quanto a LO são gramáticas do tipo LALR(1). Como objetivo de construir a ferramenta mais genérica possível, foram realizados estudos sobre três ferramentas, com as quais as transformações são possíveis. São elas: YACC, SINLEX e GG. É feita uma breve descrição destas três ferramentas e uma comparação com o protótipo implementado. / Languages transformation or transformation among differents formats of the same language is a subject that , has had a lot of interest for t many years. Thus, research has been done aiming to automatize the proccess of transformation from one notation to another. This work describes the use of Transformation Grammars to describe the necessary transformations to convert from a Source Language (SL) notation to an equivalent Object Language (OL). The concept of Attribute Grammars is embbeded to these grammars, defining an Attributed Transformation Grammar (ATG). A transformation tool prototype to evaluate the ATGs is presented. This tool generates a translator from SL to OL using the SL grammar description and the corresponding transformation rules to the OL. Both the SL and OL are LALR(1) grammars. Studies on YACC, SINLEX and GG (tools wich allow transformations) were done trying to reach the most generic tool. A brief descriptions of these tools and a comparision with the prototype is presented.
