Klessydra-T: Designing Vector Coprocessors for Multi-Threaded Edge-Computing Cores
share
Convolutional computation kernels are fundamental to today's edge computing applications. Interleaved-Multi-Threading (IMT) processor cores are an interesting approach to pursue the highest energy efficiency and lowest hardware cost in edge computing systems, yet they need hardware acceleration schemes to deal with heavy computational workloads like convolutional algorithms. Following a vector approach to accelerate convolutions, this study explores possible alternatives to implement vector coprocessing units in IMT cores, showing the application-dependence of the optimal balance among the hardware architecture parameters.
