摘要: 本论文主要针对离散弦转换之超大型积体电路阵列设计提出一个有系统的
设计方法,此方法分别从演算法、硬体架构及实现方式等三方面加以分析
考量,采取回旋列式演算法、心脉式阵列架构与以记忆体为结构基础之实
现。利用此项方法所设计的阵列,比传统利用乘法器之心脉式阵列及近年
来流行的分散式算术为基础之阵列更能节省硬体成本。此外,本论文亦推
导了一个针对多维离散哈特利转换的新列式,利用此列式可以避免以传统
方法设计所带来的额外代价。
This dissertation presents a systematic approach to design VLSI
arrays for the discrete sinusoidal transforms. Considering from
the aspects of algorithm, architecture, and implementation, the
presented approach adopts the cyclic convolution formulation,
systolic array realization, and memory-based implementation.
Using the presented approach can yield VLSI array designs which
are more efficient in hardware than the conventional systolic
arrays based on multipliers and the distributed arithmetic
architectures. In addition, in this dissertation, we also
develop a new formulation for the multi-dimensional discrete
Hartley transform such that we can avoid the undesirable
overhead in the hardware designs resulted from the conventional
design approach.
