VLSI Projects

Very large scale integration (VLSI) technology is the enabling technology for a whole host of innovative devices and systems that have changed the way, we live. This integration allows us to build systems with many more transistors on a single IC. The EDA tools and complex hardware devices such as complex programmable logic devices (CPLDs) and field programmable gate arrays (FPGAs) allow to develop special-purpose systems that are more efficient than general-purpose computers. In the 1960s Gordon Moore, an industry pioneer, predicted that the number of transistors that could be manufactured on a chip would grow exponentially. His prediction, now known as Moore’s Law. Moore’s ultimate prediction was that transistor count would double every 18 months. Over the past thirty years, the number of transistors per chip has doubled about once a year. The Intel microprocessors is good example in the growth in complexity of integrated circuits. The Table 1.1 shows the several generations of the microprocessors from the Intel.
