Embodiment Construction

[0011] The core of the present invention is to utilize the virtual memory mechanism of the modern operating system. Traditional operating systems such as DOS do not have a virtual memory mechanism, and all processes share a unified memory space. The operating system directly allocates memory according to process requirements, which will lead to many problems such as data insecurity, system instability, low memory usage efficiency, and insufficient space. Modern operating systems such as Windows, Linux, and MacOS have adopted virtual memory mechanisms. In the virtual memory mode, the operating system allocates memory in two steps: the first step is to allocate memory address space, which can be relatively large, but does not actually allocate memory; the second step is to submit memory requests, and allocate memory according to actual needs, not A full allocation of the previously requested memory address space is required. Through the virtual memory mechanism, the memory addr...

Abstract

The invention provides a multi-path data quick processing method. The invention discloses a multi-channel data processing method. Allocating a relatively large memory address space to each path of data to be used as a cache; initially, only a small part is requested to be actually allocated, and when a certain path of data cannot be processed in time due to network jitter or short time, the allocated memory cache is exhausted and more memory is needed, more physical memory requests are submitted to the operating system, so that on-demand expansion is realized. And when a certain path of allocated memory is more and the required memory is not more after the data is processed in time, the more allocated physical memory can be released.

Description

technical field [0001] The invention belongs to the field of computer information processing and relates to a fast processing method for multi-channel data. Background technique [0002] When a large amount of computer data is transmitted and processed, due to the inconsistency of information input, processing, and output, it is necessary to establish a cache for the input data. The existing method of establishing a cache is to directly allocate a large block of memory, which is not a big problem when there is only one way of data. When multiple channels of data are input at the same time and a cache needs to be established, if the caches are managed separately, the memory demand may be too large. If the caches are managed together, the multiple channels of data are easily interleaved, which greatly increases the management complexity and reduces the processing efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a multi-channe...
