Abstract
- A novel direct digital frequency synthesis (DDFS) architecture based on the differential CORDIC (DCORDIC) algorithm is presented. The architecture allows digit-level pipelining in the CORDIC angle path by implementing a two-dimensional systolic array. Unlike other DDFS architectures, it incorporates the phase accumulator in the digit-level pipelining framework so that a bottleneck-free datapath throughout the whole system is achieved in a scalable manner. A generic environment that generates fully synthesizable Verilog codes that implement the proposed architecture is created and the physical attributes of the resulting system are discussed.
