Verifying serial buses and components in embedded designs

Embedded systems typically involve a number of serial communications links running between microcontrollers, peripheral chips and the outside world. Before working firmware is completed, designers often need to confirm that a peripheral chip is working as expected. One efficient way to do this is by correlating inputs or outputs with serial bus data being sent between the chip in question …

HD aggregation & packet services accelerate video switch/router bandwidth

Video switching has encountered two technology trends that together are changing tasks in the professional studio radically. Native signals used in video editing evolved from analog to SD(standard definition) digital, then quickly to HD (high definition) and several higher-ban ***a***dwidth standards. At the same time, video aggregation that once was characterized by point-to-point dedicated digital streams is poised to …
