Full textToday electronic devices contain more and more features due to emergence of new embedded applications. The interesting point which comes with feature-rich platforms, from hardware designer's point of view, is that lots of features cannot be executed at the same time. The mutually exclusiveness of different features gives the possibility of hardware resource sharing between applications, among other optimization. Designers can implement those using different architectures like CPUs, FPGAs or ASICs. However the higher cost of silicon pushes researchers to find better solutions. Thus, to have a good trade-off between flexibility and performance, Multi-Mode Systems are proposed. This work proposes a new optimization methodology for mutually exclusive applications which contains common logic resources. It takes the advantage of the possibility of resource sharing between applications knowing that resources cannot be used at the same time. A given set of mutually exclusive applications are synthesized and combined in a single multi-mode ASIC called mASIC. This methodology allows to create a multi-mode circuit without changing the hardware description of the input applicationsMASIC generation techniques are also performed to generate a multi standard RF receiver. ZigBee, WiFi and Bluetooth standards are developed separately in the context of the ANR funded project “ASTECAS”. Knowing the fact that they have common resources like adders and multipliers, we used mASIC optimization methodology to share resources between 3 standards

Full textAs feature sizes scale down to nano-design level, electronic devices have become smaller, more performant, less power-onsuming, but also less reliable. Indeed, reliability has arisen as a serious challenge in nowadays’ microelectronics industry and as an important design criterion, along with area, performance and power consumption. For instance, physical defects due to imperfections in the manufacturing process have been observed more frequently, impacting the yield. Besides, nanometric circuits have become more vulnerable during their lifetime to ionizing radiation which causes transient faults. Both manufacturing defects and transient faults contribute to decreasing reliability of integrated circuits. When moving to a new technology node, Field Programmable Gate Arrays (FPGAs) are the first coming into the market, thanks to their low development and Non-Recurring Engineering (NRE) costs and their flexibility to be used for any application. FPGAs have especially attractive characteristics for space and avionic applications, where reconfigurability, high performance and low-power consumption can be fruitfully used to develop innovative systems. However, missions take place in a harsh environment, rich in radiation, which can induce soft errors within electronic devices. This shows the importance of FPGA reliability as a design criterion in safety and critical applications. Most of commercial FPGAs have a mesh architecture and their logic blocks are gathered into clusters. Therefore, this thesis deals with the fault tolerance of basic blocks (clusters and switch boxes) in a mesh of clusters FPGA. These blocks are mainly made up of multiplexers. In order to improve their reliability, it is imperative to be able to assess it first, then select the proper hardening approach according to the available budget. So, this is the main outline in which this thesis is conceived. Its goals are twofold: (a) analyze the fault tolerance of the basic blocks in a mesh of clusters FPGA, and point out the most vulnerable components (b) propose hardening schemes at different granularity levels, depending on the hardening budget. As far as the first goal is concerned, a methodology to evaluate the reliability of the cluster is proposed. This methodology uses an existent analytical method for reliability computation of combinational circuits. The same method is employed to identify the worthiest components to be hardened. Regarding the second goal, hardening techniques are proposed at both multiplexer and transistor levels. At multiplexer level, two hardening solutions are presented. The first solution resorts to spacial redundancy and concerns the logic block structure. A novel Configurable Logic Block (CLB) architecture baptized Butterfly is introduced. It is compared with other hardened CLB architectures in terms of reliability and cost penalties. The second hardening solution is a redundanceless scheme. It is based on a “smart” synthesis that consists in seeking the most reliable design in a given founder library, instead of directly using a redundant solution. Then, at transistor level, new single-ended and dual-rail multiplexer architectures are proposed. They are compared to different other transistor structures, according to suitable design metrics

Full textThis thesis focuses on the design and the validation of an embedded FPGA dedicated to critical applications which require a high level of security and confidentiality. Nowadays FPGAs exhibit many weaknesses toward security: 1- They are not intended to efficiently support alternative styles of circuits such as asynchronous circuits. 2- The place and route flow is not completely manageable by the user in order to target our security goal. 3- They are not protected against side channel attacks such as DP A, EMA or DF A. Ln order to overcome these technological problems, the work presented in this thesis proposes an architecture that supports the programming of different styles of asynchronous circuits. Ln addition, it presents a secure programming system and a design that ensurcs a high-Ievel of security against the attacks mentioned above. Finally, the circuit prototype has been evaluated in order to validate the relevance of the proposed solutions

Full textThe Software Defined Radio (SDR) techniques aim at offering an access to a broad choice of radio communications standards on a flexible hardware (HW) architecture which is necessary in order to answer the diversity of the processing to carry out. The digital communications techniques involve heterogeneous resources needs. The reconfigurability of a heterogeneous HW platform is thus a key features to a successful appearance of SDR systems. The reconfigurability of a SDR system must meet the needs for adaptation of the processing functions to answer the requirements of the contexts switching. Our work is based on the analysis of the baseband processing in the transmitting chains of the 3 standards UMTS, GSM and 802. 11g. We propose an analysis of factorization of the multistandard baseband processing in order to reduce the number of contexts to be managed and we determine the needs for flexibility of SDR applications. In this context, the configuration management of HW platforms clearly appears as the key feature of a SDR system. We propose a Hierarchical and Distributed Configuration Management (“HDCM”) approach in order to meet the needs of managing various types of flexibility of dataflow oriented applications mapped on heterogeneous HW. The implementation of applications on reconfigurable heterogeneous platforms and in particular on configurable logic devices, requires the uses of new design methodologies in order to extract the potential reconfigurability of these reconfigurables devices. We bring in this work various design methodologies that aim at designing partially and dynamically reconfigurable systems on chip and on FPGA

Full textDays after days, new dynamically reconfigurable circuits provides more flexibility and possibilities to implement various algorithms. If progress is significant with regard to the material, an efficient implementation is hard to define according to this new flexibility. It provides to the developers a vast field of solutions meeting their needs. Today, available reconfigurable circuits from the main FPGA companies do not have efficient methods and tools necessary to a good management these components. The goal of this work is to provide tools allowing a complete exploration of the possibilities offered by dynamic reconfiguration for the implementation of an algorithm. We can thus give to the developers an overview of the performances that such or such manner of splitting its application will achieve. The result is then to allow an faster , simpler and less constraining implementation using the dynamic reconfiguration which still appear complex to a beginner in the world of reconfigurable computing

Full textSecurity of digital processing is important in our society. Many applications require high levels of security and/or safety. To meet these requirements, applications often use ASIC components. The main problems of such devices are that they are dedicated to one application and require high production volumes. Another possible approach is to use reconfigurable platforms such as SRAM-based FPGAs. However, the configuration memory of such FPGAs is sensitive to perturbation, thus requiring a specific study. The main goal of this thesis is to characterize the fault injection effects obtained in such devices using lasers and power glitches. In this work, we analyze for a given FPGA the sensitivity of the elements configuring the logic and we identify the main types of modification patterns in interconnections. Fault attack effects have been studied with respect to several parameters: laser spot size or power glitch amplitude, perturbation duration and energy. The determinism of the effects was also analyzed. It was shown for the laser attacks that the shape of sensitive areas depends on the initial bit state and an interpretation was proposed. Based on these characterizations, an AES crypto-processor secured against fault-based attacks was implemented on the FPGA and then attacked. Robustness differences with the ASIC implementation were particularly analyzed and countermeasure improvements were proposed, implemented and validated
