Siva Satyendra is currently working as a Postdoctoral Researcher for the project "Predictive Self-learning Control for Building Facades Using FPGAs (PRÄKLIMA FASSADE)". He has obtained his Ph.D. from the National University of Singapore, Singapore. His doctoral thesis focused on Cross-layer Reliability for Heterogeneous Embedded Systems and spanned from 2015-2019. He completed his masters (M.Tech) from the Indian Institute of Science, Bangalore in 2010-2012 in the specialization Electronics Design Technology. His master's thesis focused on Hardware Accelerator for Support Vector Machines. He has also worked with Intel India, Bangalore during 2012-2014 in the domain of Physical Design. His work at Intel focused on improving reliability during SoC Integration of dense integrated circuits for smartphones/tablets. His research interests include Embedded Systems, Machine Learning, Reconfigurable Computing, Reliability-aware Computing Systems, and System-level Design.

Abstract
Modern embedded systems need to cater for several needs depending upon the application domain in which they are deployed. For example, mixed-critically needs to be considered for real-time and safety-critical systems and energy for battery-operated systems. At the same time, many of these systems demand for their reliability and security as well. With electronic systems being used for increasingly varying type of applications, novel challenges have emerged. For example, with the use of embedded systems in increasingly complex applications that execute tasks with varying priorities, mixed-criticality systems present unique challenges to designing reliable systems. The large design space involved in implementing cross-layer reliability in heterogeneous systems, particularly for mixed-critical systems, poses new research problems. Further, malicious security attacks on these systems pose additional extraordinary challenges in the system design. In this paper, we cover both the industry and academia perspectives of the challenges posed by these emergent aspects of system design towards designing high-performance, energy-efficient, reliable and/or secure embedded systems. We also provide our views on paths forward.

Abstract
Dynamic Partial Reconfiguration (DPR) enables resource sharing in FPGA-based systems. It can also be used for the mitigation of aging-related permanent faults by increasing the number of redundant Partially Reconfigurable Regions (PRRs). Normally, these PRRs are able to host any of the Partially Reconfigurable Modules (PRMs), or tasks, at one particular instance. This kind of system is called homogeneous. However, the FPGA resource constraints limit the amount of homogeneous redundancy that can be used and hence affect the lifetime of the system. This issue can be addressed by utilizing the heterogeneous approach where each PRR now only hosts a subset of the tasks. Further, the deadlines of the applications must also be taken care of in the design phase to decide the mapping and scheduling of tasks to PRRs. To this end, we propose an application-specific multi-objective system-level design methodology to determine the appropriate number of PRRs and the mapping and scheduling of tasks to the PRRs. Specifically, we propose a lifetime-aware scheduling method that maximizes the system's mean time to failure (MTTF) with different tolerances in the makespan specification of an application. We use the scheduler along with an automated floorplanner for design space exploration at design-time to generate a feasible heterogeneous PRR-based system. Our experiments show that the heterogeneous systems can offer more than 2x lifetime improvement over homogeneous ones. It also offers better scaling with increased tolerance in makespan specification.
