Understanding PowerVR Series5XT: PowerVR’s market leading fillrate efficiency

   

It’s easy to talk about a lot of architectural benefits and features, but ultimately the proof is in actual measurable recognisable efficiency benefits. It’s for this reason that our design teams make use of hundreds of focus tests to ensure that the hardware is able to sustain peak throughput performance in a wide range of […]

Understanding PowerVR Series5XT: YUV colour space conversions and the 2D core

       

Simple 2D operations continue to be very common in embedded systems. But as modern embedded GPUs increasingly become GFLOPS monsters to handle advanced functionality such as complex 3D graphics and compute, they become increasingly less efficient at handling simple 2D data movement operations. Data handling with PowerVR’s dedicated 2D core Staying true to the concept […]

The emergence of HEVC and 10-bit colour formats

      

In case you haven’t seen the latest headlines, Imagination recently announced PowerVR D5500, the world’s first multi-standard 10-bit video decoder that is able to handle the H.265 (HEVC) standard at 4K (Ultra HD) resolution. H.265, which was officially ratified earlier this year, aims to provide roughly double the data compression of the H.264 standard currently […]

Understanding PowerVR Series5XT: PVRTC, PVRTC2 and texture compression

          

One of the biggest contributors to bandwidth in mobile graphics is the bandwidth linked to texture mapping. This is especially true with increasing screen resolutions, as ever-higher resolution textures are required to maintain image quality, and thus ever more data is being read by the GPU. Reducing texture bandwidth and power with PVRTC and PVRTC2 Imagination recognised […]
