The current focus of the Center is to research and develop handheld smart devices, which include two prospective key technologies:

  • 5G mobile communications technology
  • Heterogeneous multicore mobile computing platform

 

The research content is summarized as follows:

Key technology 1: 5G mobile communications technology

        Owing to the anticipation of the world for 5G mobile communications systems, the International Telecommunication Union Working Party 5D (ITU-R Working Party 5D) of the United Nations began drafting the Framework and Overall Objectives of the Future Development of IMT for 2020 and Beyond” since the 2012 World Telecommunication Development Conference (WTDC). The goal was to outline the 5G market, technologies, applications, and spectral efficiency demands by the time of the WTDC in 2015. To satisfy a data traffic demand 1000 times that of the current demand, the following technological improvements are necessary: improved bandwidth and spectral efficiency (i.e., being “green”), increased network density and transmission speed (i.e., being of “high performance”), and enhanced network intelligence (i.e., being “soft”).Concerning network construction, a method involving the coexistence of small cell and large cell will be adopted. For this method, the 10GHz–60GHz band transmission technology becomes a viable technology for small cells. The academia and the industries also began to research and develop 5G mobile communications systems in 2012. These companies included Qualcomm, Intel, Samsung, Ericsson, Nokia-Siemens Network, NTT DoCoMo, Orange, EU METIS Project, UK 5G Project. The research objectives were also included in China’s863 program. However, regardless of the early efforts made by these companies in the R&D of 5G technologies, no further progress can be made until ITU-R Working Party 5Dannounces the 5G system framework in 2015. Therefore, the Project aims to promptly deploy the necessary human resources to carry out related research work to develop unique technologies so that it will come out on top in the first round of the world’s 5G technology competition; this will enable the 5G technology framework developed by the Center to gain international recognition and allow it to become a part of the5G technology framework to be used.

 

Key technology 2: Heterogeneous multicore mobile computing platforms

        Regarding the computing efficiency of mobile computing platforms in recent years, that of GPUs (i.e., FLOPS/W and FLOPS/mm2) has significantly outperformed that of CPUs. However, CPUs now face various obstacles such as poor parallel processing efficiency, slow two-way heterogeneous core data transmission, and high power consumption and drawing operation load. Traditionally, CPU and GPU cores are increased to improve computing efficiency. Nevertheless, improvements in computing efficiency made using this method are limited; therefore, wafer suppliers began to adopt the perspective of processor design and examined the feasibility of CPU and GPU-based heterogeneous multicore collaborative computing in optimizing wafer efficiency. The design of application processor thus expanded from homogeneous multicore computing to heterogeneous multicore collaborative computing. However, the emergence of heterogeneous multicore collaborative computing presents new technological challenges to vendors in the eco system. To solve these challenges, seven world-class mobile computing companies comprising AMD, ARM, Imagination, MediaTek, Qualcomm, Samsung, and Texas Instruments established the HSA Foundation in 2012. The objective was to develop open standards for the industry to be followed in the development of software and hardware architecture, software development tools, and develop compatible heterogeneous multicore eco systems, which will enable software designers to maximize the advantages of heterogeneous multicore collaborative computing (i.e., high performance and low power consumption), providing additional applications and value innovations.
