Processor (computing)In computing and computer science, a processor or processing unit is an electrical component (digital circuit) that performs operations on an external data source, usually memory or some other data stream. It typically takes the form of a microprocessor, which can be implemented on a single metal–oxide–semiconductor integrated circuit chip. In the past, processors were constructed using multiple individual vacuum tubes, multiple individual transistors, or multiple integrated circuits. Today, processors use built-in transistors.
Excavator (microarchitecture)AMD Excavator Family 15h is a microarchitecture developed by AMD to succeed Steamroller Family 15h for use in AMD APU processors and normal CPUs. On October 12, 2011, AMD revealed Excavator to be the code name for the fourth-generation Bulldozer-derived core. The Excavator-based APU for mainstream applications is called Carrizo and was released in 2015. The Carrizo APU is designed to be HSA 1.0 compliant. An Excavator-based APU and CPU variant named Toronto for server and enterprise markets was also produced.
