The synchronous read method of proposition vegetables circulation tracing of safety information system information of the present invention in serial transfer (disk, communication), extensively adopts CRC (CRC).CRC adds a few bit check sign indicating numbers to information code, with code distance and the debugging error correcting capability that increases whole coded system.The theory of CRC is very complicated, the method for calculation check sign indicating number after the existing generator polynomial of an introduction on the general book.Error detecing capability is relevant with generator polynomial, can only memorize mechanically according to the conclusion on the book.The ultimate principle of CRC (CRC) is: after the information code of K position, splice the check code of R position again, whole code length is the N position, and therefore, this coding is (N, K) sign indicating number again.Given (N, K) sign indicating number can prove that having high order power is the polynomial expression G (x) of N-K=R for one.Can generate the check code of K position information according to G (x), and G (x) is called the generator polynomial of this CRC sign indicating number.The concrete generative process of check code is: suppose transmission information with message polynomial C (X) expression, with C (x) the R position that moves to left, then can be expressed as C (x) * 2R, the R position will be vacated in the right of C (x) like this, the position of Here it is check code.Is exactly check code through C (x) * 2R divided by the remainder that generator polynomial G (x) obtains.
Adopt its realization principle of redundancy check algorithm to see Fig. 6, the generation step of CRC sign indicating number: 1) the inferior R+1 bit that converts correspondence for the generator polynomial G of R (x) to of the highest power of x.2) the information code R position that moves to left is quite with corresponding message polynomial C (x) * 2R.3) generator polynomial (binary number) is done mould 2 to information code and is removed, and obtains the remainder of R position.4) remainder is pieced together the position of vacating after information code moves to left, and obtains complete CRC sign indicating number.
The synchronous read method of proposition vegetables circulation tracing of safety information system information of the present invention; The optimum static scheduling algorithm of situation of not considering n=1 is can be through the analysis of task schedulability is carried out in the calculating of resource utilization ratio; Algorithm is simple, effective, is convenient to realize.Any one conclusion all has a model hypothesis, 1) all task requests all are periodic, must in the time limit that limits, accomplish; 2) operation of task is accomplished before must taking place in the next operation of this task, has avoided consideration formation problem like this; Here, we do not do special differentiation to task and operation, because a task requests is exactly an operation.3) all be independently between the task, the request of each task does not rely on the beginning or the completion of other task requests; 4) be constant the working time of each task, and be finger processor is used to handle this task under no interruption situation time the working time of task here; 5) all aperiodicity tasks are all moved under special situation, such as the improper emergent management program of system initialization or system.6) some other hypothesis such as uniprocessor, can be seized scheduling, and the time that task is switched ignores or the like.
Adopt priority algorithm realization principle to see Fig. 7,1) and task Ti (Pi, Ci, Di) model: the cycle is Pi, and be Ci computing time, and time limit Di is the cycle terminal point.Task discharges in cycle starting point, and high-priority task can be seized the execution of low priority task.2) priority method: stationary is distributed.Priority and cycle are inversely proportional to, and the cycle, short more priority was high more.3) schedulability analysis: if task-set satisfies following formula, then this task-set can be dispatched.
Priority algorithm with source synchronous constraint when between real-time task during shared resource, low priority task possibly occur and block the situation that high-priority task is carried out unpredictablely, cries pirority inversion.At this moment the RMS algorithm can not guarantee the scheduling of task-set, must use the inversion time of relevant agreement control priority.Agreement commonly used has top agreement of priority and heap resource protocol, and using these agreements can make the inversion time of priority is at most the execution time of a resource critical section, and deadlock can not take place.
