Gerenciamento de tags na arquitetura ChipCflow - uma máquina a fluxo de dados dinâmica

Abstract

The alternative architectures and softwares researches have been growing in the last years. These researches are happening due to the advance of hardware technology and such advances must be complemented by improvements on design methodologies, test and verification techniques in order to use technology effectively. Many of the alternative architectures and softwares, in general, explore the parallelism of applications, differently to von Neumann model. Among high performance alternative architectures, there is the Dataflow Architecture. In this kind of architecture, the execution of programs is determined by data availability, thus the parallelism is intrinsic in these systems. The dataflow architectures become again a highlighted research area due to hardware advances, in particular, the advances of Reconfigurable Computing and FPGAs (Field-Programmable Gate Arrays). ChipCflow project is a tool for execution of algorithms using dynamic dataflow graph in FPGA. The main goal in this module of the ChipCflow project is to define the tagged-token format, the iterative operators that will manipulate the tags of tokens and to implement them.
