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.
