Paper Abstract

This paper describes a new address generation unit (AGU) architecture for video signal processing. The proposed AGU has several sophisticated addressing modes obtained by analyzing many video signal processing algorithms, and can generate image memory addresses needed in video signal processing. This AGU's architecture was employed in a DSP being developed at present. In this paper, first of all, the architecture of the DSP and the role of the AGU are presented. Furthermore, the details of this AGU, such as the control method, addressing modes, and operations of the AGU in some typical applications are described.
