Microprocessors are the engines that drive the modern world. For decades this space has been dominated by large manufacturers, such as Intel and AMD, which design and fabricate a range of stand-alone processors. However the proliferation of small computing devices such as cellphones, laptop computers, and internet-enabled appliances has opened a significant new niche the Application Specific Standard Product ASSP microprocessor. These processors usually start out as soft-cores that are parameterized at design time to realize exclusively the specific needs of the application. The microprocessor is a small part of a working system and requires peripherals such as DRAM controllers and communication sub-systems to properly carry out its function. Therefore, creating a full system requires significant top-level integration.
