Task time twoport register is also connected with the tasks carrying CPU, to obtain the task time in assignment instructions；
Task status reads register and is connected with the task status twoport register, to read task status；
Task time distribution register is connected with the task time twoport register, to read task time；
Task triggering starts register and the task status reading register and is connected to obtain task status, also with it is described
Task time distribution register connects to obtain task time；
The tasks carrying CPU starts register triggering to perform task according to the task triggering being attached thereto；
The task action result that the task data register obtains it from the tasks carrying CPU, sends to communication
Interface CPU is exported.
Realizing a technical scheme of above-mentioned purpose is：A kind of real-time control method of portable main website is provided, it includes：
The assignment instructions received are sent to task data register by communication interface CPU；
Tasks carrying CPU is read after assignment instructions from task data register, and it is double that task status is sent into task status
Mouth register, will also be sent to task time twoport register task time；
Task status is read after the task status that register reads task status twoport register, and output task status is taken office
Business triggering starts register；
Task time distribution register was read after the task time of task time twoport register, and output task time takes office
Business triggering starts register；
Task triggering starts register root according to the task status and task time received, is performed to trigger tasks carrying CPU
Task, tasks carrying CPU, which exports task action result, gives task data register, and then is delivered to by task data register logical
Communication interface CPU is exported.
The real-time control system and method for a kind of portable main website provided as a result of the present invention, the shape of tasks carrying
State, time and trigger event cached according to twoport in parameter parallel work-flow, realize the distribution of portable main station system task
Stablize relatively, with efficiency high, the advantage that performance is good, cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The real-time control system that a kind of portable main website is given in Fig. 1, figure is refer to, including：Task status reads and posted
Storage, task status twoport register, task time distribution register, task time twoport register, task triggering startup are posted
Storage, tasks carrying CPU, task data register and communication interface CPU.
Wherein, communication interface CPU, task data register, tasks carrying CPU are sequentially connected；Via tasks carrying CPU's
One output end is sequentially connected task time twoport register, task status and reads register；Via the another of tasks carrying CPU
Individual output end is sequentially connected task time twoport register, task time distribution register；Task status reads register and appointed
Business time distribution register starts register via task triggering respectively and takes back tasks carrying CPU.
In the real-time control method of the portable main website provided based on said system, the present invention, communication interface CPU will be received
Assignment instructions be sent to task data register；
Task status is sent to task status twoport by tasks carrying CPU after task data register reading assignment instructions
Register, will also be sent to task time twoport register task time；
Task status reads the task status that register reads task status twoport register, task time distribution register
Read the task time of task time twoport register；
Task status reads register and exports task status to task triggering startup register, task time distribution register
Task time is exported to task triggering startup register；
Task triggering starts register triggering tasks carrying CPU and performs task, and tasks carrying CPU is defeated by task action result
Go out to give task data register, and communication interface CPU outputs are delivered to by task data register.
The present invention operation principle be：Using the operation principle of parallel processing timing, there is provided a kind of reality of portable main website
When control system and method, realize stablizing relatively for portable main station system task distribution, with efficiency high, performance is good, into
This low advantage.
The present invention is described in detail above in association with accompanying drawing embodiment, those skilled in the art can be according to upper
