Abstract

A highly fault tolerant transmitter digital block for zigbee physical layer (IEEE 802.15.4) is implemented with bio-inspired embryonic cell array, on commercially available Vertex FPGA. The 2.99K gates e-cell consists of gene memory, 32 bit MIPS based eDNA processor and built-in logic block observer (BILBO). Five e-cells are self organized to perform the transmitter function. When any BILBO detects a fault during operation, the faulty cell is replaced by the unassigned cell after activating the corresponding eDNA. The zigbee transmitter returns to normal operation after 66 cycles, and this on the fly self-cure is applicable to highly mission critical communication at over 200MHz operation.
