Тhe article presents a Radiation tolerant heterogeneous Multi-core ASIC MC-30SF6 as the SoC (Systemon-Chip) for the onboard "intelligent" signals and images processing systems. MC-30SF6 based on a CMOS 180nm Radiation tolerant library and consists of the five ELVEES IPcores for the processing and compression data with extra performance more than 9 GFLOPs. The SoC design and architecture support fault tolerance against SEU errors. SoC has built-in multichannel multiprotocol SpaceFibre/GigaSpaceWire (SpaceWire-RUS standard)/SpaceWire embedded networking subsystem. The networking subsystem provides multiple ports for high-rate interconnection with combination of SpaceWire/GigaSpaceWire/SpaceFibre links. SoC support four ports GigaSpaceWire/two ports SpaceWire switch. Input and processed data streams transmitted via 1.25 Gbps two multiprotocol SpaceFibre/GigaSpaceWire and four GigaSpaceWire links. Two SpaceWire links (ECSS-Е-50-12С) provide data transfer bandwidth from 2 up to 400 Mbps. The MC-30SF6 embedded networking subsystem on the base SpaceWire/GigaSpaceWire/SpaceFibre provide a balance between ASIC throughput and SoC performance especially for the multifunctional micro and nanosatellites systems.Index Terms -Radiation tolerant heterogeneous Multicore ASIC, multiprotocol SpaceFibre/GigaSpaceWire based links
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
