PowerVR
PowerVR is a family of graphics processing units (GPUs) originally developed by Imagination Technologies. Here is a detailed overview:
History
- Origin: The PowerVR technology was initially developed in the early 1990s by VideoLogic, a company founded by Sir Hossein Yassaie, who later founded Imagination Technologies in 1992.
- Acquisition: Imagination Technologies acquired the PowerVR technology in 1997 when it purchased VideoLogic's graphics division.
- Evolution: Over the years, PowerVR GPUs have evolved significantly, moving from simple 2D graphics acceleration to complex 3D rendering capabilities used in various applications, including mobile devices, gaming consoles, and automotive systems.
Technology
PowerVR GPUs are known for their:
- Tiled Rendering: PowerVR uses a technique called tile-based rendering, which divides the screen into smaller areas or tiles for more efficient memory usage and power consumption.
- Deferred Rendering: This approach allows for the rendering of complex scenes by first rendering geometric elements, then applying shading and lighting effects in a separate pass, reducing overdraw.
- Power Efficiency: PowerVR GPUs are designed with a focus on power efficiency, making them particularly suitable for battery-powered devices like smartphones and tablets.
Applications
- Mobile Devices: PowerVR GPUs are found in numerous mobile devices, notably in Apple's A-series chips used in iPhones and iPads until the A10 Fusion chip.
- Automotive: PowerVR technology is used in automotive infotainment systems, offering high-quality graphics while maintaining energy efficiency.
- Embedded Systems: They are also used in various embedded systems requiring high graphical performance in a low power envelope.
Notable Features
- Scalability: The architecture of PowerVR GPUs allows for scalable performance, suitable for a range of devices from entry-level smartphones to high-end gaming devices.
- API Support: PowerVR supports multiple graphics APIs like OpenGL ES, Vulkan, and DirectX, providing flexibility for developers.
Recent Developments
- Acquisition by Canyon Bridge: In 2017, Imagination Technologies was acquired by Canyon Bridge, a private equity fund, which was a move to ensure the continued development of PowerVR technology amidst financial difficulties.
- New GPUs: Recent releases include the PowerVR Series9XTP for high-performance applications and the Series8XEP for entry-level and mid-range devices.
