Abstract

In this brief, we propose a low-area-cost fault-aware high-reliability Polar decoder VLSI architecture, resisting the unexpected faults randomly occurring in the internal storage elements. As for 2048-bit codeword length, our developed triple-mode chip can be well-reconfigured to perform SC decoding and SCL decoding with the list size (L) of 2 or 4. In the ASIC implementation with TSMC 40-nm multi-Vt CMOS technology, the total core area of our work only occupies 0.769 mm2 in chip layout, operating at a maximum frequency of 666.67 MHz. As compared with other state-of-the-arts, only our chip work can support high-reliability capability under 7.4% area overhead only.
重构SC和SCL译码的故障感知高可靠性三模极性译码芯片的低面积成本VLSI架构
在本文中,我们提出了一种低区域成本的故障感知高可靠性Polar解码器VLSI架构,可以抵抗内部存储元件随机发生的意外故障。对于2048位码字长度,我们开发的三模芯片可以很好地重新配置,以执行SC解码和SCL解码,列表大小(L)为2或4。在采用台积电40纳米多vt CMOS技术的ASIC实现中,我们的工作在芯片布局上的总核心面积仅为0.769 mm2,最高工作频率为666.67 MHz。与其他最先进的技术相比,只有我们的芯片工作可以在7.4%的面积开销下支持高可靠性。
