The minimum memory self-adaptive mechanism and usage method on the bd-java platform

Abstract

The invention belongs to the technical field of computer software, and provides a self-adaptation mechanism and a usage method of a minimum memory on a BD-java platform. The self-adaptation mechanism comprises the BD-java platform which consists of a BD-java module and a virtual file system. The BD-java module comprises an application cache manager, an audio cache manager and a typeface manager. The BD-java module is connected with the virtual file system. Virtual equipment comprises a temporary audio storage module, a temporary typeface storage module and a temporary decompression zip file storage module. The virtual file system is used for sending the audio, typeface and file cache information which is transmitted from the BD-java module to the corresponding temporary audio storage module, the temporary typeface storage module and the temporary decompression zip file storage module so as to store the temporary information of clients. The self-adaptation mechanism and the usage method of the minimum memory on the BD-java platform have the advantages of complying with memory, performance and BD codes at the same time and being applied to the 256M BD-java platforms.

Description

technical field [0001] The invention belongs to the technical field of computer software, and in particular relates to a minimum memory self-adaptive mechanism on a BD-java platform and a usage method. Background technique [0002] Since the release of BD specification version 1.0 in 2002, all manufacturers have designed hardware performance based on software requirements, resulting in almost all manufacturers producing hardware with higher specifications and higher costs than market expectations. As more manufacturers join in, competition in the Blu-ray player market intensifies, and reducing costs and increasing living space are the goals pursued by all manufacturers. Reducing hardware configuration is an important part of this process. As far as system memory space is concerned, the mainstream trend is still 512M and 384M BD-java platforms, so reducing memory usage can directly reduce costs. However, for different hardware platforms, such as PCs and BD players, hardware ...

AI Technical Summary

Problems solved by technology

However, for different hardware platforms, such as PCs and BD players, hardware performance and memory buffer size vary greatly, resulting in different software requirements, performance and function requirements for different platforms, resulting in differences in BD-Java platforms under different platforms very large, poor compatibility

[0003] The traditional technology generally has the following problems: the hardware platform is very different, and the performance requirements are also different. The design of the BD-Java platform is difficult to achieve in one step. Although there are many ways to reduce memory and various implementation methods, so far there is no A common technology can use both BD specifications, performance and memory can be used

Generally, the method adopted is to reduce functions and sacrifice performance, and cannot flexibly realize dynamic memory allocation and scheduling. However, the Java platform in BD has many functions involved in its specifications, large memory usage, and complex scheduling, making it difficult to maintain Reduce memory for certain performance

[0004] The BD-Java platform currently on the market is difficult to run on the BD player with 256M memory, and its performance is also subject to many restrictions. It is also difficult to simply and directly transplant the BD-Java platform running on the 256M player platform to the computer platform
