The first time I got in touch with computer was during my childhood years, and I was deeply appealed to this giant “electrical toy”. In the following years, my connections with computer became even stronger. I had attempted to compile some simple programs, for example, the Gluttonous Snake game, during my middle school years, and got many rewards back as I took part in programming contests later on. Entering college, I proactively sat in some computer subjects and fully immersed myself in this fascinating world. Computer architecture, in particular, aroused my interests, for it helps to improve my programming skills and execution efficiency based on a comprehensive
（这个说提升编程能力有点牵强，建议去掉）
understanding of the computer’s inner structure. It was so amazing in my mind, and I cannot stop my pursuit into this area. Now, standing at the crossroad of my life, as a response to my inner passion, I decide to transfer to computer engineering, to realize my ambition of being an outstanding engineer in the field of computer architecture.



At Zhejiang University, one of the top 3 universities in China, I specialized in its Electronic Information Engineering program, the VLSI
（把its去掉，直接讲专业。还有先讲小的，specialized in VLSI track in Electronic Information Engineering）
track. This track has close relevance with computer architecture. For example, I learned how to compose and debug codes, design CPU architecture, and to take into the account of computer structure while working on computer programming. It is also worth mentioning
（and take into account去掉to和the； while改成when）
that most of my academic researches I did at college were relevant to computer architecture. Therefore, I am confident to say that all my previous educational background and research experiences have well prepared me for a master’s degree in computer engineering.



With my career goals clearer, I pushed myself to undertake more advanced theoretical study and research opportunities. From March to
（With my career goals becoming clearer）
May 2016, as a junior college student, I assisted Professor Weiwei Wang in the project of Designing Pipeline RISC CPU, with the goals being designing a data path and a controller for the processor. As part of a team, I was mainly responsible for reducing the effects of

data hazards that were caused by pipelining, to which I contributed a great deal of time and efforts. Finding that the usually employed method, bypass algorithm, was unable to largely reduce the cost, I then searched for a vast ocean of materials before deciding to use Tomasulo, a kind of dynamic scheduling algorithm, to prevent the pause of pipelines to the maximum degree. However, another problem, the mismatching problem between processor and memory, occurred. To solve this problem, I self-learned the page replacement algorithm and added a cache to the system based on the self-adapting page replacement algorithm, which realized the function of detecting the access patterns dynamically and choosing the most suitable replacement algorithm without artificial

intervention. My efforts helped to realize a 30% increase in the cache accuracy performance, an accomplishment that I feel highly proud of. Now, we are sorting our research outcomes, which are expected to be published in a core journal.



After completing that project, I soon got involved in the Summer Research Training Program and worked on a project named Vehicle License Plate Recognition System based on CUDA. As for my part, the most difficult task was to identify the character recognition. To
（去掉to indentify the）
offer satisfactory solutions, I applied Support Vector Machine (SVM) learning algorithm to character recognition process. A twice recognition was also applied to tell apart similar characters such as number “0” and letter “D”. To solve the time cost for training SVM model caused by the Sequential Minimal Optimization (SMO) training algorithm, I creatively brought in the CUDA architecture and planted SMO parallel (P2SMO) algorithm on the platform of CUDA, which helped to increase the efficiency of the SMO algorithm. Moreover, I made modification to the P2SMO by taking into account of the rapid convergence conditions and the changes of kernel function cache table access strategy. Based on these efforts, I achieved a satisfactory result as the parallel algorithm speed realized rapid progress, almost ten times of its equivalent, and the recognition accuracy reaching up to 90.12% in the test. Our research achievements eventually won the Excellent Scientific Research Project Award of Zhejiang University. During the process, I comprehensively employed the knowledge in machine learning, computer architecture, image processing, and became more skilled in realizing the parallel computing of CPU and GPU.  



I believe the best way to understand an industry is to get actual practices. With such determination, I decided to seek first-hand experience in real world. Beginning from the May this year, I obtained a six-month internship at the Distributed Storage Development

Department of Huawei Technologies Co., Ltd, and was selected to join the project of Designing and Implementing Distributed Memory File Caching System. Our research team discovered that there existed a large amount of physical memory that could not be completely

pool and promote the entire execution efficiency. For me, I am mainly responsible for the functions of file storage distribution service, free memory supervision, as well as distribution forecast. I combined both LRU replacement algorithm and global updating for the pheromone module to minimize the system consumption and to maximize the authenticity of the module simultaneously.
After comparing the performance of distributed memory file caching system and the disk read performance via NFS, I found that the former realized a 200% jump in file throughput capacity in the computer cluster connected by Ethernet. From this project, I became aware of the significance of distributed storage in enhancing the overall working efficiency and became more determined to become a proficient in the area of computer architecture. Driven by this ambition, I declined the promising job offer from Huawei and decided to

start another academic pursuit.



I was first attracted to University of California, San Diego by the ranking of your College of Engineering. It is one of the best schools in
（rank，不过不建议一开头就说这个，总感觉不要这么赤裸裸）
computer science, technology, and engineering in the world. With more in-depth research, I find that I can benefit greatly from your
（find-> found）
excellent teaching, multiple research opportunities, and cooperation relations with local enterprises. After enrollment to your Master’s degree in Computer and Science Engineering, I hope to become part of NVSL (The Non-Volatile Systems Laboratory) and focus on the researches on fast non-volatile memories architecture. By attending the weekly seminars and exchanging ideas with intellectual minds in this area, I could better prepare myself to become a specialist in the high-performance storage system design. I firmly believe that under the support of your high-quality education, I will thrive as a computer engineer capable of tackling advanced scientific problems and important societal challenges, which will make my life meaningful and rewarding.

It will be a great honor for me to get admission to the CSE program at UCSD. Upon graduation, I will join an IT company in Silicon Valley, such as Apple or Intel, to specialize in computer architecture design and development. With years of working experiences accumulated,
（with->after）
I, in the long run, aspire to establish my own company to create and produce IT products with competitiveness and influential power. Starting from childhood curiosity, I’ve developed my interest in computer into a practical career aspiration through intensive study and valuable internships. Your education will complement my pursuit and I cannot wait to start next phase of my life at UCSD.
