The execution process of a program can be seen as a continuous function call. When a function is executed, the program will return to the next instruction (followed by the call instruction) of the calling instruction for further execution. A
Complete parsing of heap and stack in C ++
Memory Allocation:
Heap: the operating system has a linked list that records the idle memory address. When the system receives a program application, it traverses the linked list to find the heap node with
An improved method for processing uC/OS-II Task Stack
Abstract:In the μC/OS-II kernel, different tasks use independent stack space, the size of the stack is defined by the maximum stack depth required by each task, this method may cause a waste of

1. Introduction (Why use stacks?) )In general, it is important to decide how to store data in such a way that data is automatically given in a specified order when it is retrieved. Stacks and queues are a common data structure for retrieving data.
