description: Soft errors are expecting to be accelerated with the shrinking of feature sizes due to low operating voltages and high circuit density. However, soft error rates per single-bit is expectedly reduced with technology scaling. With tight requirements for the area and energy consumption, using a low complexity and high coding rate error correction code (ECC) to handle soft errors in on-chip communication is necessary. In this work, we use Parity Product Code (PPC) and propose several supporting mechanisms to detect and correct soft errors. First, PPC can work as a parity check to detect single event upset (SEU) inside each flit. Then, to reduce the needed retransmission, a Razor flip-flop with parity check (RFF-w-P) is proposed to work with PPC. Since PPC can act like forward error correction (FEC), we also present a selective transmission in bit-indexes by using  a transposable FIFO. Therefore, the proposed mechanism not  only guarantee single error detection/correction but also provide 2+ error correction as FEC. The proposed work also reduce the area cost of FIFO in comparison to traditional coding methods and adapt too multiple error rates.
