## Body

### Definition and Classification
The ATI Xenos is a **graphics processing unit (GPU) model** developed by **ATI Technologies**. It falls under the broader class of **graphics processing units**, which are specialized electronic circuits designed to accelerate the creation of images and animations. As a GPU, the Xenos acts as a **graphics accelerator** and functions as a **coprocessor**, operating in conjunction with the system's main CPU. It is technically defined as a **vector processor**, meaning it is architected to efficiently handle operations on large arrays of data (vectors) in parallel.

### Application in Xbox 360
The Xenos is the specific GPU used by the **Xbox 360**. In this context, it serves as the central component for graphics rendering within the console's architecture. By utilizing the Xenos, the Xbox 360 is able to offload complex graphical calculations from the main processor, allowing for the generation of rich, high-resolution visual experiences.

### Manufacturer and Development
The chip was manufactured and designed by **ATI Technologies**. Within the industry, ATI is recognized for producing various GPU architectures, including the Radeon series (introduced in 2000). The source material notes that ATI also designed the "Hollywood" chip for the Nintendo Wii, placing the Xenos among the company's significant contributions to gaming hardware.

### Technical Context and Components
As a GPU, the Xenos shares the fundamental characteristics of its hardware class. It is distinct from a "graphics card" (the assembly that includes the chip, memory, and cooling), existing instead as the silicon component itself. While specific internal specs for the Xenos are not detailed in the provided text, GPUs of this class typically comprise:
- **Shader Pipelines:** For processing vertex and pixel shaders.
