SpaceCube is a Field Programmable Gate Array (FPGA) based on-board hybrid science data processing system developed at the NASA Goddard Space Flight Center (GSFC). The goal of the SpaceCube program is to provide 10x to 100x improvements in on-board computing power while lowering relative power consumption and cost. The SpaceCube design strategy incorporates commercial rad-tolerant FPGA technolog...

In the last decade, optics has proved a key technology for the transmission and handling of broadband signals in telecommunication networks. Future telecom satellite payloads will have to receive, process, route and re-transmit an increasing number of microwave signals. We have been investigating how the technologies inherited from terrestrial optical communications may bring substantial improv...

This paper addresses key mechanisms for service provisioning in non-geostationary satellite constellations employing intersatellite links (ISLs). To this end, several recent research contributions on ISL routing and signaling, and on satellite diversity and handover are summarized and presented in an integrated manner to show their interplay towards end-to-end service provisioning. The focus wi...

To reduce the transfer load of the digital pulse shape acquisition systems applied to the large area telescope of the 4π-multidetector CHIMERA, we have tested an architecture based on a new sampling ADC-board equipped with two TigerSHARCs, a new generation digital signal processor, and able to perform on-board the Event Parameter computation. In this contribution we present the preliminary resu...

One of these tasks is a process called "transformer" that transforms the Objects defined in Real World coordinates into viewing coordinates (Image Space) according to the viewing position and direction. Objects are represented by planar and convex polygons. In this way the viewing transformation of objects is reduced to the transformation of points, namely the vertices of the polygons. The tran...

This article presents PAPRICA-3, a VLSI-oriented architecture for real-time processing of images and its implementation on HACRE, a high-speed, cascadable, 32-processors VLSI slice. The architecture is based on an array of programmable processing elements with the instruction set tailored to image processing, mathematical morphology, and neural networks emulation. Dedicated hardware features al...

This paper describes a system to teach programming on an interactive electronic whiteboard that combines the merits of classroom lectures using a black/white board and those of computer processing. Using this system, a teacher can write a program on the board, explain it, make the system recognize it and run the program in front of the class while keeping the attention of the students focused o...
