Data caching method and device

Abstract

The invention provides a data caching method and device, which are applied to the Internet of Vision. The method includes: the Internet of Vision terminal applies for a set number of memory blocks as a memory pool for data caching by calling the preset memory application function in the operating system; the Internet of Vision terminal receives the Internet of Vision server based on the Internet of Vision protocol, According to the data packet issued by the downlink communication link configured for the Internet-of-TV terminal; the Internet-of-TV terminal allocates the target memory block required by the data packet from the memory pool, and caches the data packet in the in the target memory block. The present invention can only call the memory application function in the operating system once initially to apply for a larger memory as a memory pool, and directly allocate memory blocks from the memory pool during subsequent data caching, so there is no need to call dynamically and frequently The operating system can avoid segment faults in the memory application function when it is called frequently, and improve the stability of the system.

Description

technical field [0001] The invention relates to the technical field of Internet of Things, in particular to a data caching method and a data caching device. Background technique [0002] With the rapid development of network technology, two-way communications such as video conferencing, video teaching, and videophone are widely used in users' life, work, and study. During the communication process, the terminals of the communication parties can transmit data to each other. After receiving the data, the terminal first caches the data and performs corresponding processing, and then decodes and displays the data. [0003] In the prior art, each time the terminal receives data, it calls the operating system to apply for memory of the size required by the data. Therefore, the operating system needs to be called frequently, and frequent calls will cause errors in the system, thereby reducing the stability of the system. Contents of the invention [0004] In view of the above p...
