Abstract

A system and a method for flexibly interrupting data processing are provided. A register for receiving input data in packets is connected to a time control unit, which is used to count the interval time from packet to packet so as to determine whether to output a first interruption signal according to the result obtained by comparing the time interval with a predetermined threshold time. And, a counting control unit is used to count the number of the packets input in the register, so as to determine whether to input a second interruption signal according to the result obtained by comparing the number of the input packets with a predetermined threshold number. The first and second interruption signals are output to a processing unit, allowing the processing unit to determine whether to temporarily interrupt the input of packets in terms of a built-in program. This thus permits the processing unit to process data input in the register.

System and method for packet data. [Background of the Invention] Currently known data transmission and processing methods, taking the network as an example, are mostly transmitted in packets; usually, when a packet is received, an interrupt signal is issued. The control temporarily stops the current work of the processing unit and starts processing the input packet data. Therefore, the conventional data processing method is to generate an interruption signal for each packet input to notify the processing unit to process the packet. After processing, the processing unit returns to The situation before the interruption is to wait for the next interruption signal to be generated and then process the next packet. This method is relatively fixed and inflexible. If network data transmission is frequent, interruptions will often be generated to cause the processing unit to process the input packet data, and Because there is a delay time regardless of the transmission of the interrupt signal, the conversion of the operation of the processing unit, and the input and output of data, the efficiency of processing data by the processing unit is reduced. [Summary of the Invention] In view of the shortcomings of the above-mentioned conventional technology, the main object of the present invention is to provide a data processing system and method with flexible interruption which can improve data processing efficiency. Another object of the present invention is to provide a data processing system capable of generating an interruption signal flexibly, so that the processing unit can perform the data interruption in a timely and balanced manner regardless of whether the data transmission is frequent or not.
