From equations to hardware.
Advances in VLSI technology make it possible to realize systems of very high complexity in a small volume of hardware using integration. In many application fields, it is necessary to implement certain algorithms, or even complete information processing systems, directly in silicon. Application domains which are likely to benefit are in the fields of signal processing and scientific computing, with applications to telecommunications, medical imaging, speech processing, image analysis and compression, radar and sonar, etc.
The design of an application specific architecture is a long and difficult task, which spans many different steps, ranging from functional specification, simulation, to chip partitioning design and assembly, making use of different techniques and tools.
The main goal of the design process can be started simply: to try to obtain a VLSI system which meets the performance and specification requirements of the project, at as low a cost as possible. To reach this, several major goals must be reached:
- The system must be safe and reliable. This means that the functional behavior of the system should be correct, and if possible, proved to be correct.
- The design time should be as short as possible. Indeed, the cost of the total system depends heavily on this parameter, not only because manpower is costly, but also since short time-to-market is a crucial factor of success especially when the technology is changing so fast.
- The system must be efficient, i.e. optimal in hardware cost and speed. In fact, the goal is most often to reach a system which just meets some given speed requirement, while minimizing real-estate in term of silicon.
