Transputer-like multicore parallel processing on the array of ARM Cortex-M0 microprocessors

Small ARM Cortex-M0 PC boards MARY linkable to form an array network for parallel processing were applied to realtime multi-tasking DSP. Multiple MARY boards coordinate the multi-tasking DSP process via four directional communication ports of (N, S, W, E) without using the shared memory like the Transputer (developed in 1980´s) works. The validity of the Transputer concept applied to a low-end embedded microprocessors was studied in the context of DSP.
