Currently, the density of transistors that electronic devices now allow is such that the integration of complete digital systems in a single integrated circuit is now possible. With the aim of reducing the period of design and development and enabling the tackling of these kinds of designs possible, these are made up of a base of modules or cores. Given their complexity, these modules often include one or more processors, whereby, in these cases, multi-processor systems are possible.
This level of integration has also been extended to reconfigurable FPGA devices, this alternative being one of the most utilised given the flexibility that it offers. However, the most common use of its capacity for reconfiguration is limited in order to facilitate the prototype phase of the design and, in other cases, to carry out subsequent updates thereof.
Nevertheless, the most recent FPGAs allow part of their configuration to be modified while the rest of the configured circuit continues to operate. This ability, known as dynamic partial reconfiguration, is of particular interest in the design of digital systems involving modules in a single integrated circuit. In these cases, the procedure carried out on the chip can also determine changes of context for the circuits or programmes of the modules and then apply them.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
