The Optimization Design of Adder-based Distributed Arithmetic and DCT Processor design

가산기-기반 분산 연산의 최적화 설계 및 이를 이용한 DCT 프로세서 설계

The Process of Inner Product has been widely used in a DSP. But it is difficult to implement by a dedicated hardware because it needs many computation steps for multiplication and addition. To reduce these steps, it is essential to design efficient hardware architecture. This paper proposes the design method of adder-based distributed arithmetic for implementation of DCT module and the automatic design of summation-network which is a core block in the proposed design method. Finally, it shows that the proposed design method is more efficient than a ROM-based distributed arithmetic which is the typical design method.
