Abstract

This paper presents a LDPC decoder chip supporting all 19 modes in IEEE 802.16e system. An efficient design strategy is proposed to reduce 31.25% decoding latency, and enhance hardware utilization ratio from 50% to 75%. Besides, we propose an early termination scheme that can dynamically adjust the number of iterations. The multi-mode chip can be maximally measured at 83.3 MHz with only 52 mW power consumption. The core area is 4.45 mm2 and the die area is 8.29 mm2.
用于IEEE 802.16e系统的19模8.29mm2 52-mW LDPC解码器芯片
本文提出了一种支持IEEE 802.16e系统全部19种模式的LDPC解码器芯片。提出了一种有效的设计策略,可将解码延迟降低31.25%,并将硬件利用率从50%提高到75%。此外,我们还提出了一种可以动态调整迭代次数的提前终止方案。该多模芯片的最大测量频率为83.3 MHz,功耗仅为52 mW。芯面积4.45 mm2,模面积8.29 mm2。
