摘要:
Provided is a low density parity check decoder, which includes a bit node calculating unit configured to calculate a bit node, a check node calculating unit configured to calculate a check node, a control unit configured to control calculation of the bit node and the check node, and a storage unit configured to store calculation values of the bit node or the check node, wherein the control unit calculates the bit node or the check node so that the node calculations are overlapped, by using an address offset value of the storage unit, thereby reducing a decoding time.
摘要(中):
提供了一种低密度奇偶校验解码器,其包括:被配置为计算比特节点的比特节点计算单元,被配置为计算校验节点的校验节点计算单元,被配置为控制比特节点和校验节点的计算的控制单元 以及存储单元,其被配置为存储所述比特节点或所述校验节点的计算值,其中,所述控制单元通过使用所述存储单元的地址偏移值来计算所述比特节点或所述校验节点,使得所述节点计算重叠, 从而减少了解码时间。
