Tile Based Deferred Rendering (TBDR) architecture

All PowerVR GPUs are based on our unique Tile Based Deferred Rendering (TBDR) architecture; the only true deferred rendering GPU architecture in the world. TBDR combines two complementary architectural features to provide the very highest levels of efficiency and performance.

Tile-Based Rendering

The PowerVR architecture splits the screen into a number of ‘tiles’, which are then processed individually (in parallel to other tiles). Since the GPU only needs to work on a subset of the complete scene data at any given time, this data (such as colour and depth buffers) is small enough to be stored in internal GPU memory, significantly reducing the required number of accesses to system level memory. This results in lower energy and bandwidth consumption and also higher performance.

Deferred Rendering

PowerVR deferred rendering uses a unique, patented method of Hidden Surface Removal which defers all texturing and shading operations until the visibility of each pixel in the tile is known – only the pixels that will actually be seen by the end user consume processing resources. This means that unnecessary processing of hidden pixels is eliminated, which further ensures the lowest possible bandwidth usage and number of processing cycles per frame, resulting in the highest performance levels and the lowest power consumption.

Virtualization and Security

GPU virtualization is now a must-have for a range of next-generation applications, from automotive, to consumer electronics, to the IoT. GPUs that implement hardware virtualization can provide isolation between the various applications/OSs for increased security, as well as maximum utilisation of the underlying GPU hardware. PowerVR GPUs, from Series6XT onwards, support hardware virtualization and in Series8XT its capabilities have been further enhanced.

PVR3C Compression

PowerVR GPUs feature PVR3C Triple Compression, a suite of three compression technologies to ensure the most efficient use of memory bandwidth. Image compression (PVRIC), texture compression (PVRTC, ASTC) and geometry compression (PVRGC) can significantly reduce system-level memory accesses required by the GPU. Benefits of reduced memory bandwidth consumption include lower power consumption, better overall system efficiency and reduced system-level memory costs.

PVRIC4

Available in future PowerVR GPUs, PVRIC4 implements a dual-pipeline architecture that simultaneously passes data through lossless and visually lossless compression pipelines and automatically chooses between them to deliver a guaranteed minimum 50% reduction in memory footprint and at least a 50% reduction in system bandwidth. This enables SoC manufactures to reduce costs and optimise power consumption.

Texture

Enabling the compression of textures can significantly reduce application file size and download times; it also dramatically improves runtime performance and power consumption by keeping bandwidth usage to an absolute minimum. PowerVR GPUs provide support for a number of industry-standard texture compression formats.
Geometry icon

Geometry

To manage the increasing geometry complexity of 3D scenes, PowerVR GPUs can include PVRGC (PowerVR Geometry Compression) . PVRGC minimises memory usage by automatically compressing the intermediate geometry parameter data that is written to memory as part of the tiling process. The data is then automatically decompressed as it is read back into the GPU later in the pipeline.
