Abstract

The future high-end embedded systems applications are characterized by their computation-intensive workloads, their high-level of parallelism, their large data-set requirements, and their dynamism. Those applications require highly-efficient manycore architectures. In response to this problem, we designed an asymmetric homogeneous with dynamic allocator manycore architecture, called AHDAM chip. AHDAM chip exploits the parallelism on all its granularity levels. It implements multithreading techniques to increase the processors’ utilization. We designed an easy programming model and reused an automatic compilation and application parallelization tool. To study its performance, we used the radio spectrum sensing application from the telecommunication domain. On a simulation framework, we evaluated sequential and parallel versions of the application on 2 platforms: single processor, and AHDAM chip with a variable number of processors. The results show that the application on the AHDAM chip has an execution time 574 times faster than on the single-processor system, while meeting the real-time deadline and occupying 51.92 mm2 at 40 nm technology.
