摘要：
When using wideband signals, the Digital Down Conversion (DDC) operation is an important operation. The development of a modern hardware base allows the implementation of DDC devices based on standard processors (CPU) and graphics processing units (GPU). The article discusses an implementation based on Overlap And Save algorithm. Comparison of computational costs and execution speed on CPU and GPU is carried out. The estimation of the maximum number of devices implemented on various models of CPU and GPU has been made.
