Wikipedia
Excavator

Excavators (Hydraulic Excavators) are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which uses winches and steel ropes to accomplish the movements.

Excavator (microarchitecture)

AMD Excavator Family 15h is a microarchitecture developed by AMD to succeed Steamroller Family 15h for use in AMD APU processors. 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 will also be available.

Excavator has been confirmed to be AMD's final revision of the 'Bulldozer' family, with two new microarchitectures replacing Excavator a year later. The next generation sister architectures will be the x86-64 Zen and AArch64 K12 architectures.
