FPGAs and JTAG – A Look at Some Developments

Taking a short break from what may be seen as our tendency to concentrate on the “snazziest” looking developments in technology, let’s look at some interesting developments in the world of mid- to lower-range FPGAs. By that we mean devices with 150k or fewer logic elements that are in growing demand for an increasing variety of system uses. Far from the “glue logic” of old, these devices are taking on roles in aerospace and defense and industrial automation as well as wireline and wireless infrastructure. Their roles include a rich variety of I/O processing and translation, packet switching, traffic management, system management and security.
