This paper introduces a scalable hardware and software platform applicable for demonstrating the benefits of the invasive computing paradigm. The hardware architecture consists of a heterogeneous, tile-based manycore structure while the software architecture comprises a multi-agent management layer underpinned by distributed runtime and OS services. The(More)
Processor architectures with Fine-Grained Reconfigurable Accelerators (FGRAs) allow for a high degree of adaptivity to address varying application requirements. When processing computation intensive kernels, multiple FGRAs may be used to execute a complex function. In order to exploit the adaptivity of a fine-grained reconfigurable fabric, a runtime system(More)
Multi-tasking is one of the main requirements for complex embedded systems to fulfill user expectations (e.g. flexibility of the system), increase the resource utilization, and thus increase the system efficiency. In general, the flexibility and efficiency can be increased by incorporating a fine-grained reconfigurable fabric (e.g. an embedded FPGA) that is(More)
Register allocation is one of the most time-consuming parts of the compilation process. Depending on the quality of the register allocation, a large amount of shuffle code to move values between registers is generated. In this paper, we propose a processor architecture extension to provide register file permutations by which the shuffle code can be(More)
Processors with an embedded runtime reconfigurable fabric have been explored in academia and industry started production of commercial platforms (e.g. Xilinx Zynq-7000). While providing significant performance and efficiency, the comparatively long reconfiguration time limits these advantages when applications request reconfigurations frequently. In(More)
Application-specific accelerators may provide considerable speedup in single-core systems with a runtime-reconfigurable fabric (for simplicity called "fabric" in the following). A reconfigurable core, i.e. processor core pipeline coupled to a fabric, can be integrated along with regular general purpose processor cores (GPPs) into a reconfigurable multi-core(More)
Runtime reconfigurable processors provide a large degree of flexibility that allows them to dynamically adapt to different applications and requirements. They couple a standard processor with a runtime reconfigurable fabric (like an embedded FPGA) to offload computationally intensive kernels. In this paper we present the design and architecture of a(More)
