Abstract Advances in electromyographic (EMG) sensor technology and machine learning algorithms have led to an increased research effort into high density EMG-based pattern recognition methods for prosthesis control. With the goal set on an autonomous multi-movement prosthesis capable of performing training and classification of an amputee’s EMG signals, the focus of this paper lies in the acceleration of the embedded signal processing chain. We present two Xilinx Zynq-based architectures for acc...

Many modern compute nodes are heterogeneous multi-cores that integrate several CPU cores with fixed function or reconfigurable hardware cores. Such systems need to adapt task scheduling and mapping to optimise for performance and energy under varying workloads and, increasingly important, for thermal and fault management and are thus relevant targets for self-aware computing. In this chapter, we take up the generic reference architecture for designing self-aware and self-expressive computing sys...

Due to the continuously shrinking device structures and increasing densities of FPGAs, thermal aspects have become the new focus for many research projects over the last years. Most researchers rely on temperature simulations to evaluate their novel thermal management techniques. However, these temperature simulations require a high computational effort if a detailed thermal model is used and their accuracies are often unclear.In contrast to simulations, the use of synthetic heat sources allows ...

Self-aware computing is a paradigm for structuring and simplifying the design and operation of computing systems that face unprecedented levels of system dynamics and thus require novel forms of adaptivity. The generality of the paradigm makes it applicable to many types of computing systems and, previously, researchers started to introduce concepts of self-awareness to multicore architectures. In our work we build on a recent reference architectural framework as a model for self-aware computing...

Run-time reconfiguration has the potential to allow reuse of resources and the reduce cost of FPGA-based systems. To compute feasible placement locations for PR modules in such systems, multiple constraints have to be evaluated. This includes unused area, placement of heterogeneous resources and communication requirements of the PR module. To improve resource utilization, both polyomino shaped PR modules and PR modules with layout variants have been suggested. In order to compute placement locat...

Run-time reconfiguration provides an opportunity to increase performance, reduce cost and improve energy efficiency in FPGA-based systems. However, run-time reconfigurable systems are more complex to implement than static only systems. This increases time to market, and introduces run-time overhead into the system. Our research aims to raise the abstraction level to develop run-time reconfigurable systems. We present operating system extensions which enable seamless integration of run-time recon...

The ReconOS operating system for reconfigurable computing offers a unified multithreaded programming model and OS services for threads executing in software and threads mapped to reconfigurable hardware. The OS interface lets hardware threads interact with software threads using well-known mechanisms such as semaphores, mutexes, condition variables, and message queues. By semantically integrating hardware accelerators into a standard OS environment, ReconOS allows for rapid design-space explorat...

A heterogeneous system with soft CPU tailored to the individual threads of the application, while still software based, offers the potential for improved performance and resource utilization over a homogeneous system. In this paper we present a method to automatically create a heterogeneous multi-core system from a multithreaded software application. The resulting system consists of processing elements based on customized MIPS soft CPUs coupled with their respective programs. Using instruction s...

Due to the continuously shrinking device structures and increasing densities of FPGAs, thermal aspects have become the new focus for many research projects over the last years. Most researchers rely on temperature simulations to evaluate their novel thermal management techniques. However, the accuracy of the simulations is to some extent questionable and they require a high computational effort if a detailed thermal model is used. For experimental evaluation of real-world temperature management ...
