System for controlling data storage

Abstract

A storage-control system of data is prepared as carrying out signal interaction with two storage-control modules by a nonvolatile storage, carrying out signal interaction with two processor systems by two said storage-control modules for carrying out data read-write operation on nonvolatile storage according to operation command of processor systems, carrying out signal interaction with two storage-control modules by arbitration module for obtaining operation state of storage-control module and for controlling write operation of two storage-control modules on nonvolatile storage.

Description

technical field [0001] The invention relates to electronic information storage and processing technology, in particular to a data storage control system for a dual-processor system. Background technique [0002] With the rapid development of electronic information technology, the processing speed of the processor in the electronic system is getting faster and faster, but the volume is getting smaller and smaller. Therefore, many electronic systems currently include two sets of processor systems, which include two sets of processors. The system is also called a dual-processor system. Dual-processor systems have been applied in many electronic information processing fields. For example, dual-processor systems are used in dual-mode mobile phones in the field of mobile communication terminals. [0003] In a dual-processor system, especially when the two processors need to work independently and cooperate with each other, the currently used program storage method is that the two...

Problems solved by technology

[0005] First, this technical solution is not enough for the resource utilization and flexibility of the dual-processor system. The storage space of the two processor systems needs to use different sizes of memory according to their respective needs, and each memory must have surplus storage space, which results in a waste of storage space

[0006] Second, using this structure is not conducive to the sharing of storage resources, and also causes waste of resources and manpower

When two sets of processor systems have the same function calls, this structure can only put the same function functions into their respective memories for calling, which not only causes waste of hardware resources, but also increases the workload of users

[0007] Third, when the two sets of processor systems need some shared information, they cannot be read directly, but can only be transmitted through other communication methods, such as through a dedicated communication interface, which not only reduces the processing speed of the entire application system, but also It also increases the workload of users to write code and increases the probability of error

Therefore, this kind of dual-port RAM is not for the purpose of storing information. After the system is powered off, all information in the dual-port RAM will be lost, so it is impossible to share a storage resource in a dual-processor system.
