An effective processing on a digital signal processor with complex arithmetic capability

Digital Signal Processors with complex arithmetic capability (DSP-C) are useful for various applications. In this paper, we propose a method for the effective implementation of specific circuits with real coefficients on DSP-C. First, we show that 2D circuits and transversal circuits with real coefficients can be implemented by complex multiplications. Next, we introduce a new computational mode (advanced mode) and a new multiplier into PSI, a type of DSPC which has been proposed already, in order to process the circuits effectively. The effectiveness of the proposed method is shown by simulation.
