An Area And Energy Efficient Half-Row-Paralleled Layer Ldpc Decoder For The 802.11ad Standard |
Abstract | ||
|---|---|---|
Multi-gigabit LDPC decoders are demanded by standards such as IEEE 802.11ad and IEEE 802.15.3c. In order to achieve high throughput, most published multi-gigabit designs use row-paralleled architecture. In this paper, we proposed a half-row paralleled LDPC decoder with half layer level pipeline and single permutation network for the 802.11ad standard, which reduces the hardware resources almost by half compared to the state-of-the-art row-paralleled LDPC decoder, achieving a good trade-off between energy efficiency and area efficiency. The decoder achieves a throughput of 5.6 Gbps and consumes only 99 mW for the highest coding rate 13/16 at 5 iterations, working at 500 MHz by using 40nm G technology, yielding an energy efficiency of 3.53 pJ/bit/iteration and area efficiency of 35 Gbps/sqmm. |
