Abstract

A data processing system and its data transmission method includes creating the first data packet by the production module and transmitting it to the consumption module, executing the first or the second operation by the consumption module according to the first data packet, copying the first data indicated by the first data packet to generate the second data packet, and data processing the second data indicated by the second data packet, where the first and the second data have the same content and store different blocks in memory, and the second operation includes data processing by the first data, reducing the reference number of a corresponding data packet in the first and the second data packets by the consumption module after data processing is completed, and releasing the block of the first or the second data indicated by the corresponding data packet in memory when the reference number is zero. The application can release the occupied storage space in the memory in real time.

Description

Data processing system and data transmission method thereof Technical Field The present disclosure relates to data processing systems, and more particularly, to a data processing system and a data transmission method capable of releasing occupied memory space in a memory in real time. Background Data processing systems in the prior art often transmit data between modules in packets (packets) and use the packets after direct reference or copy of the data is determined by the module receiving the packets. However, in practical applications, the data dependency and processing timing between the modules are limited, and the above mechanism may cause the blocks storing data in the memory to be unable to be released at appropriate time points, or occupy additional memory space due to unnecessary data replication, thereby reducing system performance. Disclosure of Invention In some embodiments, one of the purposes of the present disclosure, but not limited to, is to provide a data processing system and a data transmission method capable of releasing occupied memory space in a memory in real time, so as to solve the problems of the prior art. In some implementations, a data processing system includes a memory and at least one processor. At least one processor runs a production module and a consumption module. The production module establishes a first data packet and transmits the first data packet to the consumption module.
