Preferably, the compiling master operating system is in image file, and wherein add module and specifically comprise: with module compiles is that task or function join in the image file; Main control processor is specified the part of module in the image file that loads by loading from processor and is specifically comprised: the pointer of main control processor acquisition task or function from the loading code section of image file; Main control processor sends to pointer from processor.
Preferably, main control processor pointer of acquisition task or function from the loading code section of image file specifically comprises: main control processor is according to the pointer of the task of task or function or function name acquisition task or function from the loading code section of image file.
Preferably, main control processor sends to pointer from processor and specifically comprises: main control processor sends to pointer from processor by wakeup message.
Preferably, distribute respective resources specifically to be comprised from processor: main control processor calculates and executes the task or the needed work space of function from processor; Main control processor distributes the memory headroom that equals the work space size that begins from the address of pointer to give from processor.
Preferably, use respective resources loading section module specifically to comprise from processor: from processor loading section module in the memory headroom that the address from pointer begins.
The new multinuclear of this embodiment, the loading management method of multiple operating system be by the following technical solutions:
The method of the unified management loading multi-core different operating system images of this embodiment comprises with lower module:
A, master control CPU management operating system
B, from CPU operating system
The method of the unified management loading multi-core different operating system images of this embodiment may further comprise the steps:
The first step: the operating system of master and slave CPU is compiled in the same image file;
Second step: the master cpu loading of videoing; And
The 3rd step: master cpu is given from CPU and is distributed respective resources and loading from CPU.
This embodiment compared with prior art simplified the management of the system of polycaryon processor, reduced the compiling number of times of reflection, and the reflection that is equivalent to only to compile host CPU gets final product.And simplified the loading flow process, the user need not to consider to load from CPU the problems such as distribution in space again.
This embodiment is applicable to from CPU operating system different with host CPU, and under the simple relatively situation of operating system of CPU.
The realization of whole functional is made up of two parts:
Master and slave CPU operating system will be compiled in the image file.From system is that mode with function occurs.
Start the back host CPU and load earlier, from code segment, extract address pointer then, send to from CPU again, and wake execution up from the CPU entrance function.
Fig. 2 shows the synoptic diagram according to the explanation of image file in the method for the unified management loading multi-core different operating system images of the embodiment of the invention, has illustrated from the position of CPU code segment:
The code segment file that has comprised master and slave CPU in the image file of the method for the unified management loading multi-core different operating system images of this embodiment, in general the operating system call function ratio of host CPU is more, so relative complex, can be shared from a lot of systemic-functions of CPU operating system with host CPU, so simple relatively.Its difference can add in the operating system of host CPU in the mode of a task or function.That is to say in fact and just occur in the mode of a process or task from the relative host CPU of CPU.For example can use a function, realize the circulation of a while (1) { }.
Fig. 3 shows the process flow diagram according to the method for the unified management loading multi-core different operating system images of the embodiment of the invention, and the method for the unified management loading multi-core different operating system images of this embodiment may further comprise the steps:
The first step: system powers on, and host CPU begins to load (label 100) from the default location of this processor regulation, and the position of dissimilar processor defineds is also different.Finish simple initialization (label 400) from CPU this moment, is in waiting status (label 500).
Second step: host CPU loads finishes back (label 200) according to prior agreement, and acquisition is from the code segment pointer (label 300) of CPU entrance function from the code segment of self operating system.This can directly obtain according to function name.And distributed corresponding memory source from CPU.
The 3rd step: this pointer sent to from CPU (label 310) and wake up from CPU by inside story bring into operation.Begin load operating (label 510) from the pointer address that carries from message after CPU receives wakeup message, finish loading (label 600) at last.
This embodiment is because adopt the operating system with master and slave CPU to be compiled in the same image file, master cpu is to distribute respective resources and the loading method from CPU from CPU, so it is comparatively complicated to have overcome the management of polycaryon processor system, the more problem of compiling number of times of reflection, and then reached the management effect of simplifying the polycaryon processor system.
Obviously, those skilled in the art should be understood that, above-mentioned each module of the present invention or each step can realize with the general calculation device, they can concentrate on the single calculation element, perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element, thereby, they can be stored in the memory storage and carry out by calculation element, perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
