Military appetite dwarfs data dumps News & Analysis 7/17/2000 Post a comment Over the past five years, there has been an unprecedented advancement in computing, especially in hardware size and speed. For example, in high-speed computing, a cost/performance goal of 200 billion operations per second per million dollars has been reached.
Optical computing remains in shadow News & Analysis 7/17/2000 Post a comment A close relationship between light propagation and processes involved in communications became evident in the 1950s and was described in several publications. These publications demonstrated how communications theory, mainly Fourier analysis, could be applied to optics.
Computers will be more than 1s & 0s News & Analysis 7/17/2000 Post a comment Over the last 40 years work in Maryland's Microsystems Laboratory has been directed toward developing hardware for new classes of computers. The classes can be broken into four basic types: number based, group theory based, wave based and biologically based.
MEMS enhance optical switching News & Analysis 7/17/2000 Post a comment Paralleling the exponential growth in computing muscle is an explosion in demand for communications bandwidth. Faster, cheaper access to ever-increasing volumes of data will be a major force in shaping the way we use computer technology and the way in which that technology evolves. Optical-fiber links are a key element of this bandwidth explosion.
Future of computer design lies beyond CPU News & Analysis 7/17/2000 Post a comment It is now possible to put the computational power of former supercomputers on a tiny chip of silicon and embed that system in virtually any household product. In that sense, the future of computing has already arrived.
Boston pays the price of technical success News & Analysis 7/11/2000 Post a comment Lee Merrill, a Boston-area high-tech recruiter, used to drive from Beverly to Waltham in about half an hour. But now that the region has grown along routes 128 and 495, his 30-minute jaunt often becomes a 90-minute crush of frustration.
Pay heed to fast clock edge issues News & Analysis 7/11/2000 Post a comment Faster edge rates mean designers must be more aware of such factors as termination, routing, skew adjust, component placement and zero-delay clock buffering. Addressing those issues properly helps ensure that system integrity is not compromised because of edge or wavefront propagation aberrations.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
