摘要

离散哈特利变换(DHT)是一种仅使用实值将时域数据转换为频域数据的变换。DHT可用于VLSI应用中数据的高度模块化和并行处理。我们提出了一种计算长度为2N的DHT的新算法，其中N=3和4。我们实现了乘法器，作为传统DHT中使用的简单乘法的改进。本文从时延和面积两个方面对传统的DHT算法和所提出的DHT算法进行了比较。

VHDL implementation of Discrete Hartley Transform using Urdhwa multiplier

Discrete Hartley Transform (DHT) is one of the transform used for converting data in time domain into frequency domain using only real values. DHT can be used for highly modular and parallel processing of data in VLSI applications. We have proposed a new algorithm for calculating DHT of length 2N, where N=3 and 4. We have implemented multiplier as an improvement in place of simple multiplication used in conventional DHT. This paper gives a comparison between conventional DHT algorithm and proposed DHT algorithm in terms of delays and area.
