Performance of the DCT can be improved by executing these repeated operations in parallel. However, memory operations to access the required data limit performance improvements of the parallelization. In this paper, we parallelize the DCT by using the ASIP developed in our previous work and propose an efficient memory data reorganization scheme to achieve further performance improvements of DCT parallelization.","PeriodicalId":360207,"journal":{"name":"2014 International Conference on Electronics, Information and Communications (ICEIC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130655609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the use of different compilers may result in large different performance values even if a target machine is the same. So, the compiler selection in the system development is very important. In this paper, we compare the performances of two popular compilers, GCC and LLVM in perspective of the code size and the dynamic instruction count for the EISC embedded processor. Our comparison shows that LLVM is good at optimizing calculation intensive benchmarks, and GCC performs register allocation and jump optimization better. Overall, the GCC compiler shows better performance in most EEMBC benchmarks about 18% on average in terms of dynamic instruction. Also, the compiled code size by GCC is smaller than that of LLVM by 4% on average.","PeriodicalId":360207,"journal":{"name":"2014 International Conference on Electronics, Information and Communications (ICEIC)","volume":"434 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116009605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When navigators sail to the sea, they usually go together as a convoy to avoid the problem of natural causes and human factors such as occasionally severe weather conditions and piracy. In essence, the navigators need to communicate with each other in their convoy. To evaluate the system functionality, network simulators are commonly chosen method. However, simulations contain assumptions that are not necessarily justified.
