A 2260 GOPS High-Performance and High-Precision Sub-pixel Motion Estimator-Interpolator for Real-Time 8K UHDTV for HEVC Coding in Next Generation Wireless Multimedia Applications

We present the design and evaluation of a high-performance network-on-chip (NoC) focused on telecommunication and multimedia applications that tolerate latency and bandwidth variations. The design is based on a connectionless strategy in which flits from different communication flows are interleaved in the same communication channel. Each flit carries routing information that is used by routers to perform arbitration and scheduling of the corresponding output ports in order to balance channel utilization. In order to compare our approach with others, we introduce an analytic model for the worst-case latency (WCL) of our NoC and recall those of related approaches. Analytic comparisons and experimental data show that our approach keeps average WCL lower for variable-bit-rate multimedia applications than a network based on resource reservation. For these applications, the overall throughput is larger than that of networks that perform resource reservation. A case study based on the proposed NoC shows that the average latency was 28% lower than the WCL expected for the experiment. Indeed, hard real-time flows designed considering the absolute WCL of the network will always meet the requirements of the associated hard real-time tasks, so no deadline can be lost due to network contention.

It is very important to detect the accurate rotor position of switched reluctance motor (SRM) for a high-performance switched reluctance motor drive. And, there are two main factors to influence SRMs rotor position detection, which are the accuracy of the position signal and the controllers real-time response. It cant meet the accuracy requirements to detect shaft position information by opto-couplers, so absolute encoder is used to produce the high-precision rotor position signal. Moreover, the all-digital controller based on DSP and CPLD achieves the real-time detection and applications of high-precision rotor position signal on SRM, with their strong ability on data processing and hardware logic describing. Due to adopting high-precision rotor position detection and control, it carries out successfully and improves the system performance. The experimental results show that the design is reliable and effective, which has great significance for the establishment and realization of high-performance SRM drive.
