Intel graphics and media control benefits

Each BSD allows a set of commands to decode one video stream.Д«roadwell's updates (when compared to Haswell) are summarized in the slide below. In order to tackle these aspects and build on consumer feedback, Intel made major updates to the media block / Quick Sync engine late last year.Д«roadwell was also the first microarchitecture to support two BSDs (bit stream decoder) in the GT3 variants. Haswell added JPEG / MJPEG decode to the MFX, a dedicated VQE (video quality engine) for low power video processing and a faster media sampler.ДЄround the time Broadwell was introduced, we had the major transitions taking place in the video codec front - HEVC adoption was picking up, and VP8 / VP9 was also gaining support. Motion compensation, intra prediction, forward quantization and entropy coding were done in hardware in the MFX (multi-format codec engine). Usage of the EU array enabled tuning of the algorithms. The second generation engine in Ivy Bridge moved to a hybrid hardware / software solution with rate control, motion estimation and intra estimation as well as mode decision happening in the programmable EU array. Quick Sync has evolved through the last five years, starting with limited hardware acceleration and usage of the programmable EU array in Sandy Bridge.

In advance of our full Skylake architecture analysis (coming soon), I wanted to get a head start and explain the media side (including Quick Sync and the image processing pipeline) of Skylake in a separate piece. Skylake marks the introduction of the Gen9 Intel HD Graphics technology.

At IDF in San Francisco last week, Intel provided us with lots of insights into Skylake, the microarchitecture behind the 6th generation Core series processors.
