Desarrollo de una herramienta para la generación de circuitos aritméticos aproximados

Proyecto de Graduación (Licenciatura en Ingeniería en Electrónica) Instituto Tecnológico de Costa Rica. Escuela de Ingeniería Electrónica, 2017.Approximate computing is presented as a new paradigm that among many application layers, allows the design of energy e cient circuits. This taking advantage of that many applications have some tolerance to losses in the precision of their calculations, which allows to vary the structures and in turn the logical behavior of the arithmetic units that perform these computations. This project develops a tool that is capable of generating approximate arithmetic units hardware descriptions proposed in the community, in addition to execute various processes in external simulation and synthesis tools that provide relevant information for the design of a circuit in which is desired to introduce approximations. It is then as this document rst provides the characteristics of structure and logical behavior of the developed arithmetic units, followed by the process of design of the tool that includes the considerations and restrictions taken for the description in hardware, script writing towards external tools and structure programming. Finally, several of the cases are presented for which the tool can be used while checking the correct behavior of the described units

Approximation Opportunities in Edge Computing Hardware : A Systematic Literature Review

With the increasing popularity of the Internet of Things and massive Machine Type Communication technologies, the number of connected devices is rising. However, while enabling valuable effects to our lives, bandwidth and latency constraints challenge Cloud processing of their associated data amounts. A promising solution to these challenges is the combination of Edge and approximate computing techniques that allows for data processing nearer to the user. This paper aims to survey the potential benefits of these paradigms’ intersection. We provide a state-of-the-art review of circuit-level and architecture-level hardware techniques and popular applications. We also outline essential future research directions.publishedVersionPeer reviewe
