Optical Digital Signal Processing: Is That Light at the End of the Performance Tunnel?
Design How-To 2/27/2004 Post a comment
Driven by ever more complex algorithms and more and more channels for the processor to handle, the need for more speed is escalating rapidly. Conventional DSPs are pushing the silicon technology envelope to meet the challenge. The stress of keeping pace with the demands of compute-hungry applications is only getting more severe, however, which has led some engineers and venture capitalists to consider introducing a technological discontinuity. In this case, it is light-wave processing.
Roving eye for Mars forces CCD rethink
News & Analysis 2/2/2004 Post a comment
Behind the spectacular panoramic images beamed back from Mars in recent weeks is a full-custom CCD imaging chip designed to meet the stringent demands and environmental conditions of the Martian surface. The 1,024 x 2,048-pixel chip, which handles imaging for each of the nine cameras on both the Spirit and Opportunity rovers, mandated a rethinking of CCD design.
