Embodiment Construction

[0017] The stability, efficiency and reliability of the DSP real-time application system have an inevitable relationship with the system's memory management and the effective allocation and release of memory units. Therefore, when designing a DSP application system, it is necessary to consider the design of the memory buffer pool and adopt the corresponding memory protection mechanism; make the storage resources meet the needs of the system for normal memory allocation; and be able to observe the memory usage and monitor possible abnormalities in the memory usage Circumstances: prevent the memory from crossing the boundary, occupying the operating address space of other programs, causing other programs to operate abnormally, disrupting the normal operation of the system or causing the system to crash.

[0018] In the entire storage unit operation, the method of the present invention uses the memory manager to realize the management of the defined memory segment, and uses the lock ...

Abstract

A method for protecting intenal memory includes using storage supervisor to achieve management, using locker to realize independent operation for storage, defining data structure for information statistics, monitoring utilization ratio of internal memory and mistake that may occure in address release and distribution by increasing heads of address pointer and off-normal detection units.

Description

Technical field [0001] The invention relates to a memory protection method in a DSP (Digital Signal Processing, digital signal processing) embedded application system in the communication field. Background technique [0002] With the rapid development of GSM, 2.5G, 3G and wireless local area network technologies, real-time DSP application systems have been widely used in all aspects of signal processing. The new generation of DSP processors, such as TI’s TMS320C6000 series, has an optimized CPU structure, rich peripheral interfaces, and a multi-stage pipeline mechanism. Its processing capacity can reach 4800 MIPS (million instructions per second) or higher. It is widely used in the field of multi-channel wireless and wired communication. [0003] In the process of realizing the functions of the communication system, due to the needs of data processing, the application and release of the memory unit will inevitably be involved. Due to its real-time, fast processing requirements an...
