Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] The present invention provides a new method for implementing memory pool management of embedded software. This method can not only make full use of the current advantages of general memory pools such as high efficiency, reliability, and no memory fragmentation, but can also effectively reduce, alleviate, and even Solve the memory waste that may exist in the general memory pool, so that it can better meet the requirements of embedded software development for memory allocation.

[0037] The memory pool management method of the embedded operating system of the present invention comprises the following steps:

[0038] Step 1: Configure the size and quantity of various memory blocks that the user may use, and then allocate a memory pool in the memory resources of the embedded software according to the sum of the size of the memory block used by the user and the siz...

Abstract

A method for distributing internal memory pool of embedded operation system includes distributing internal memory pool formed by internal memory block and head in internal memory source according to size internal number of various internal memory block and size of internal memory head, initializing said internal memory pool to confirm initial address of internal block in various sizes and satisfying internal memory application by combining multiple internal memory block when waste over threshold is existed at minimum single internal memory block satisfying to said internal memory application.

Description

technical field [0001] The invention relates to the field of embedded real-time operating systems, in particular to an implementation method for managing memory with an uncertain size requested by an application by using a memory pool allocated in advance in the embedded system. Background technique [0002] With the wide application of embedded real-time systems in various fields, the development of embedded software has also received more and more attention. On the premise of meeting the real-time requirements of the system, how to improve the speed, reliability and efficiency of memory allocation is a subject that needs to be studied in the embedded software system. The rapidity of memory allocation starts from the real-time requirements of the embedded system, and requires the memory to be as fast as possible during the allocation process. Therefore, in the embedded system, it is impossible to adopt the complex and cumbersome memory allocation strategy in the general ope...
