The article presents architecture and main features of 90 nm CMOS radiation tolerant MCDE50F ASIC as multiprocessor heterogeneous SoC (System-on-Chip) which contains MIPS64 RISC core, graphic processing unit (GPU) and application-specific computer vision Elcore50 DSP. High-speed data input/output is performed by multiprotocol SpaceFibre/GigaSpaceWire/ SpaceWire ports combined with built-in multichannel SpaceFibre/GigaSpaceWire/SpaceWire based switch. MCDE50F ASIC is intended for space “intelligent” surveillance system applications, which require high computational performance in signal and image processing, including computer vision functions support, and high-speed deliverance of massive data arrays. An example of onboard data processing system structure based on MCDE50F ASIC is presented. Performance characteristics of MCDE50F ASIC implementing OpenVX standard functions are also given.

AbstractUltracompact and low-power-consumption optical switches are desired for high-performance telecommunication networks and data centers. Here, we demonstrate an on-chip power-efficient 2 × 2 thermo-optic switch unit by using a suspended photonic crystal nanobeam structure. A submilliwatt switching power of 0.15 mW is obtained with a tuning efficiency of 7.71 nm/mW in a compact footprint of 60 μm × 16 μm. The bandwidth of the switch is properly designed for a four-level pulse amplitude modulation signal with a 124 Gb/s raw data rate. To the best of our knowledge, the proposed switch is the most power-efficient resonator-based thermo-optic switch unit with the highest tuning efficiency and data ever reported.

Data Acquisition And Processing

This electronic Logging while drilling (LWD) is a new sort of well drilling technology developed in recent years. As to the traditional cable borehole survey, the LWD method has many advantages because of its higher accuracy, higher geologic strata resolution capacity, much less time and cost. To meet the current logging technology needs, A data acquisition and processing system for logging while drilling is designed．It minutely introduces the collection system structure, acquisition Program, the digital design of LWD and discusses the design and the implementation of each functional module．The system which designed on the basis of the high precise DSP and FPGA implements signal pretreatment, high speed A/D control and digitalization of the phase sensitive demodulation etc, optimizes the acquisition and processing system and supplies a new way for the development of logging while drilling．Experimental results show that system performance has attained the design requirement.
