Problems solved by technology

When a task terminates, the vxworks operating system sets the state machine of the task to the dead state, but does not release the memory space occupied by the corresponding TCB, resulting in a waste of memory space
In addition, the vxworks operating system does not provide monitoring means for these tasks that have terminated but still occupy TCB memory space

Embodiment Construction

[0026] Hereinafter, the device and method for monitoring terminated tasks in the vxworks operating system of the present invention will be described in detail with reference to accompanying drawings 1-4.

[0027] As shown in FIG. 1 , it is a schematic structural diagram of a device for monitoring terminated tasks in the vxworks operating system of the present invention. The monitoring device includes a message receiving unit and a storage unit. Wherein, the message receiving unit is used to receive the messages of other tasks in the system, and sends the received messages to the storage unit; the storage unit contains the terminated task linked list, which is used to add the terminated TCB information, and according to the The terminated TCB information notifies the system to release the memory occupied by the TCB.

[0028] In addition, the monitoring device may further include an analysis unit for analyzing the message sent by the message receiving unit, identifying the mess...

Abstract

The invention provides a device for detecting the stopped mission of vxworks operating system and a relative method. The device comprises a message receiver and a memory unit, wherein the message receiver can receive the messages of other missions in the receive system and send the received message to the memory unit, the memory unit can add the stopped TCB message and inform the system to release the memory occupied by the TCB according to the stopped TCB message. The inventive device and method can release the memory waste occupied by stopped TCB.

Description

technical field [0001] The invention relates to the field of computer operating systems, in particular to a device and method for monitoring terminated tasks in the vxworks operating system. Background technique [0002] As a kind of operating system with good real-time performance, vxworks operating system is widely used in a large number of embedded systems. [0003] In the vxworks operating system, the smallest unit that can be scheduled is called a task. With the development of network technology and multimedia technology, embedded systems are designed more and more complex. In the software implementation of embedded systems based on the vxworks operating system, designers often generate a large number of tasks in the operating system. The vxworks operating system only provides simple task monitoring methods, but these methods cannot meet the user's more needs for real-time monitoring of various tasks in the system. [0004] The vxworks operating system manages and co...
