Abstract: A data processing system is provided, and pertains to the data processing field. The system includes N cascaded processing groups, including A soft processing groups and B hard processing groups, where A+B=N. Each soft processing group includes a first delay unit, an input interface, a processor, an output interface, and a second delay unit; the first delay unit is hardwired to both the input interface and the second delay unit; the processor is electrically connected to both the input interface and the output interface; and the second delay unit is hardwired to the output interface. Each hard processing group includes a third delay unit and a hardware unit; and the third delay unit is hardwired to the hardware unit. The present invention can improve data processing efficiency.
