[en] A CONTENT ADDRESSABLE MEMORY BASED ARCHITECTURE TO SUPPORT A PROLOG VIRTUAL MACHINE / [pt] UMA ARQUITETURA BASEADA EM MEMÓRIA ASSOCIATIVA PARA SUPORTE A UMA MÁQUINA VIRTUAL PROLOG

MALENA OSORIO HOR-MEYLL 12 November 2009 (has links)
[pt] As arquiteturas convencionais de computadores, baseadas no modelo de Von Neumann, não implementam eficientemente a linguagem Prolog, fundamentada em mecanismos de unificação e retrocesso automático. Este trabalho propõe a arquitetura de um acelerador, baseado a uma máquina virtual Prolog (PLM) desenvolvida na COPPE/UFRJ. A arquitetura proposta aumenta a eficiência da máquina virtual explorando o paralelismo da memória associativa na realização do mecanismo de retrocesso. O impacto no desempenho da máquina virtual decorrente da nova arquitetura foi avaliado por simulação utilizando programas clássicos encontrados na literatura. / [en] Conventional computer architectures based on Von Neumann’s model do not efficiently implement the Prolog language, founded on unification and automatic backtracking mechanisms. This work presents the architecture of a content addressable memory accelerator to be connected to a Prolog Virtual machine (PLM) developed at COPPE/UFRJ. The presented architecture increases the virtual machine’s efficiency by exploring the content addressable memory’s parallelism to implement the backtracking mechanism. The impact on the virtual machine’s performance due to the new architecture was evaluated by simulation, using classical programs found on the literature.
