Rendering hair and fur needs computer graphics muscle
News & Analysis  
7/24/2002   Post a comment
Before they became a checklist item for SoC designs, RAMDACs would convert digital RGB values to a value that lit a CRT phosphor dot - and the rendering engine came up with each RGB value was equivalent to a time-share on a Cray supercomputer. The times have changed, says this computer graphics authority, all the work is done by a single chip - cheap enough to power a kid's gaming machine. Here's how it works. . . using hair and fur as an example.

Real data cuts timing mumbo-jumbo for cascaded PLL designs
News & Analysis  
7/10/2002   Post a comment
PLLs provide the designer with the luxury of re-timing late or early clocks, eliminating the propagation delays that occur when clocks are transported over long distances. But typically there is noise and degradation - jitter - with each PLL in the chain, says this Cypress clocking expert. Here is an excellent example of timing budget measurements that can reduce the impact of noise in your system.
