Problems solved by technology

However, its real-time tasks adopt static priority, and the system interrupt response time slice is also fixed, which affects the real-time performance of the system to a certain extent.
[0006] These current operating systems all have a common problem in terms of system resource allocation: system resource allocation is based on the process that requires the use of resources, requiring the operating system to pay a lot of calculations to determine the resource allocation plan, which restricts the overall efficiency of the operating system improvement

Abstract

A resource management device of embedded real time operation system consists of core host, internal memory supervisor, file supervisor, device supervisor, network communication unit and application module. It is featured as using message mode to call system function between each unit and supervisor to carry out distribution and management on information resource i.e. confirming task property by initializing task and carrying out management and distribution treatment separately according to custom task or no custom task then carrying out dispatch operation.

Description

Technical field: [0001] The present invention relates to a system device for implementing system resource management applied to information appliances, in particular to an embedded real-time operating system resource management device for completing system resource allocation and management by means of a computer operating system kernel host technical background: [0002] At present, there are several mature embedded real-time operating system products in the world. However, most of these dedicated operating systems are commercial products, and one of their common features is that they are expensive, and because their respective source codes are not disclosed, their compatibility and openness are affected. This closedness also leads to a big problem in the important performance of commercial embedded systems in supporting various specific applications. It is difficult to modify its functions according to the requirements of specific applications, which leads to the inadequac...
