| Abstract: | The IF signal solution scheme of software defined radio which based on DDC and DSP was briefed. The circuit construction of data transferring between DDC and DSP which was realized with FIFO was expounded in detail. The data transfer-ring mode,FIFO′S writing reading timing, and the set of DSP EMIF were analyzed.The problems need to be attended in the design were pointed out according to the hardware feature. |
