AB  - In this paper, we describe a modular approach to the design of an Address 
      Generation Unit (AGU). The approach consists of development of a generic Address 
      Generation Core (AGC) as a basic building block and the construction of an AGU 
      from the AGCs. We illustrate this concept with AGUs capable of handling 2D- and 
      3D-structured data, and as well as their setup for executing 2D and 3D FFT 
      algorithms on a Field Programmable Gate Array (FPGA). The AGUs developed using 
      our proposed method are simple and easily expandable. Furthermore, they can 
      potentially support irregularly structured data which are often generated from 
      the wide variety of pulse sequences in magnetic resonance imaging. Our 
      experimental results show that these AGUs are capable of generating addresses 
      with a user-predefined pattern automatically at the speed of one address per 
      clock cycle and operate at clock rates up to 80 MHz. They can operate 
      concurrently with other processes and thus do not introduce additional operation 
      latencies. Although we focus on applying the developed AGUs to executing 2D and 
      3D FFT, we expect that the modular design method should have much wider 
      applications.
