Embodiment Construction

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

[0019] In the embodiment of the present invention, after the digital set-top box is started, it redistributes its own system memory, assigns different application programs to different memory areas to run, and establishes address mapping between physical memory and virtual memory when the application program has virtual memory requirements. Make physical memory and virtual memory work together for applications. It effectively manages the system's kernel code, high-speed buffer, virtual disk, and main memory area, facilitates the memory allocation of user applications, avoids memory conflic...

Abstract

The invention is applied to the field of computer software and provides a method, a module and a device for allocating system memory of a digital set top box. The method comprises the following steps of: starting the digital set top box, wherein the digital set top box starts to redivide the memory per se; processing corresponding application programs in different memory areas; and establishing address mapping between physical memory and virtual memory when a user application program needs to be assisted by the virtual memory. In the method, the digital set top box starts to redivide the system memory per se and allocates different application programs to different memory areas for operation. When the application program demands the virtual memory, the physical memory and the virtual memory process the application program together by establishing the address mapping between the physical memory and the virtual memory; the application program of the system memory is effectively managed;the memory allocation of the user application program is facilitated; memory conflict and overflow are avoided; and the system stability and user experience are improved.

Description

technical field [0001] The invention belongs to the field of computer software, and in particular relates to a digital set-top box system memory allocation method, module and device. Background technique [0002] With the continuous development and improvement of information processing technology, the application of digital set-top box system memory is becoming more and more complex and important. [0003] In the prior art, the application of the digital set-top box system memory is very messy: the digital set-top box system memory needs the necessary memory space for the kernel to execute the program; provides buffer space for the image displayed on the TV; provides buffer for the video data in the CPU and hard disk space and so on. Therefore, the prior art often causes memory conflicts and overflows, greatly reducing system stability and user experience. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a digital s...
