Nowadays, System-on-Chips contain many different blocks, such as digital, analog and radio RF blocks. Many problems of the design and integration of such a systems come from the power-performance-area equlibrium, and the most valuable part of this equation in recent years became a power. Driven by the rapid growth of the consumer electronics market, the need to reduce the power consumption has never been so critical. In that context, our research project focuses on the innovative architectures with ultra wide performance, ultra low power consumption and high reliability incorporating the following technologies and approaches : spinotronics, fully-depleted silicon on insulator (FD-SOI) and asynchronous communication.
Spintronics studies the spin of the electrons and its practical use in a new electronic components, which generally combine magnetic materials together with semiconductors or insulators. These components can be used for the variety of applications : logic, memory, FPGA. Research teams of SPINTEC laboratory work on the development of these components and their integration in innovative hybrid semiconductor/magnetic architectures. FD-SOI technology, developed and provided by STMicroelectronics, has the objective to serve a wide spectrum of products for military, industry and consumer applications. It brings a significant improvement in terms of performance and power saving, complemented by an excellent responsiveness to power management design techniques for energy efficiency optimization.
The asynchronous design technique makes asynchronous circuits an increasingly practical alternative to the conventional approaches. It is a promising technique for the applications with low power consumption, higher operating speed and robustness toward variations in supply voltage, temperature and fabrication process parameters, less emission of electromagnetic noise, better modularity, no clock distribution and clock skew problems.
The talk will concentrate on the basics of these technologies and briefly introduce the goals and some advances of our project.
