SUMMARY OF THESIS The necessary of the topic Many new areas such as computer graphics, artificial intelligence, number analysis, parallel calculating in the petroleum industry, the unmanned equipment, equipment of identifying monitoring mobile targets , require to process very large volumes of data with high speed Most of this problem, the sequential computer does not meet the actual requirements Research on parallel processing systems now focus two main researching directions are as follows: The one is to study multi-processor systems as supercomputers (Suppercomputer) [45], [54], large computer (Mainframe), minicomputer (minicomputer) make versatile: the hardware structure and software function of the computer that must be multi-functional organized are complex Mathematical model is very complex, beyond ordinary calculating structure Therefore, when applied to specialized applications, their processing speed is often slower than the ability of the micro processing; real-time parameter is not controlled correctly Parallel multi-processing system has a big scale together with operating structural software is very complicated Therefore, the computer system has a very expensive price This is a difficult problem to solve specific problems required high speed, low cost consistent with economic conditions in Vietnam The second is to study parallel multi-CPU processing system such as: parallel-specialized processing system for one or one class of specific math, the same function Therefore, manipulation methods,

structure of data group need to be processed; the structure of resulting data are defined before, so it is more easy to decompose functions , easy to select data organization and appropriate processing methods with speed requirements With specific tasks and defined data structures, the optimal processing algorithm can be made, appropriate hardware structure, utilizing system resources reasonably Due to the function of parallel specialized processing systems is limited and explicit, the Monitor program is built in the most optimal, highly scalable and more importantly is to response fast requirements of operational processes in the system Through the above analysis, the thesis selects the second direction that is parallel-specialized multi-CPU processing system In parallel specialized multi-CPU processing system, shared storage space (SSS) is very important: the storage of the database to be processed, the operating program When many reference flows accessed to shared memory at the same time that can lead to conflict, then the system may hang or low access speed, the performance of shared memory is reduced and does not meet the speed requirements of this problem The importance of SSS is the control set of reference flow On that basis, the problem to be solved is to synthetic the structure of adaptive controlling of reference flow to SSS to minimize the probability of conflicts when accessing shared resources, improving computing speed is very important From the above analysis, the research poses the problem for parallelspecialized multi-CPU

Through the analysis and introduction about parallel multi-CPU processing system and parallel- specialized multi-CPU processing system in section (1.4) and (1.5) With parallel - specialized multi-CPU processing system, the performance largely depends on the accessing speed into common resources, but the most importance is SSS because the highest possibility of conflict is here (because the frequency of using SSS is much higher than other resources such as I/O port, peripherals ) One of the tasks of the synthesis stage of the system is to minimize the possibility of conflict in reference to SSS of CPU unit that is a critical task For example, the monitoring system of aircrafts The aircrafts are such as: (i) at different distances (ii) the speed is also very different The parameters must be monitored for an aircraft: (i) distance (ii) azimuth and (iii) height, when the parameters are controlled, we are able to draw the flying orbits Then we can make other decisions (to kill, not

entrance reference registers is unoccupied (P is the conditional probability of entrance register is unoccupied), even when you are Q =1- P To refer successfully, we need 1/E1 test with a conditional probability P (E1 – the performance of entrance reference register is unoccupied) The probability of occupied entrance reference registers is - P to ensure a successful reference, we need 1/Ep test (Ep – The performance of busy entrance reference register) So we turn to the problem of conditional probability, with a relationship: N acc 1  P Q  N acc0 El Ep E The expression of performance is rewritten as follows: E El E p PE p  QEl (2.1) This is a mathematical model to determine the performance of shared memory’s architecture with a buffering as role of queuing at the entrance and exit of the physical memory module To determine this model and appear controlling parameters, we need calculate three components: (i) P – the probability of unoccupied entrance reference register, (ii) Ep

queuing theory model [4], [46] described in Picture 2.2.a, combined with the characteristic of parallel-specialized multi-CPU processing system, can see the architecture of shared memory as a system consisting of k independent queues according to M/D/1/m rule That means: the reference process to the shared memory is the Poission process and Markov distribution (M), the service life of the memory is determined (D); memory space for references is and queue size of each memory module is m - The probability of unoccupied entrance reference register will be determined: m P  PN i  n n0 m  1

22 3.6 Conclusion of Chapter Chapter has solved the following problems: - Develop algorithms, simulation diagram in the Delphi environment - Take out the simulation results showing that in the case of a mathematical model referring to SSS when not using buffering of queue’s size m have lower performance than the case of using the buffering of in/out queue’s size m # - Size of m is an important parameter to optimize the structure of memory according the problem class, parallel multi-CPU processing system will have not only high performance but also high reliability That is the basis for adaptive controlling structure Now size of m will be a function of the reference’s frequency of the system into SSS If you use more structures to detect and determine the frequency of accessing, it will be controlled to change queue’s size of FPGA’s structure for the memory bank to match this frequency Conclusions and recommendations The conclusions: Parallel multi-CPU processing system is increasingly widely applied in many fields, including civil and military With advanced engineering and technology currently, designing studies’ towards of parallel-specialized multi-CPU processing system has highperformance, optimal and flexible structure with class of application problem, is a correct direction The process of researching thesis has contributed new issues as follows: - Have been found and proven mathematical model allowing us to identify the accessing performance of the shared memory of parallelspecialized multi-CPU processing system as a function of memory cycles and indicates the in/out queue’s size m and the other parameters involved - The obtained results allow to calculate the configure of shared memory in parallel multi-CPU processing system It also pointed out that the more the queue m increases, the less E performance is and it is dependent on the number of reference flow that means we can increase the number of CPUs up to multi-processing systems to solve the problem of large numbers such as problems with large databases
