VXE VIDEO ENCODER IP CORE FAMILY
Imagination Technologies’ POWERVR™ VXE Video Encoder IP cores are multi-standard SD and HD video encoders. The cores encode video from raw image data, producing a compliant bit stream at the elementary stream or NAL unit level; generate stream headers; and perform algorithmic functions such as entropy encoding, scan, transform, motion estimation and compensation, and deblocking.
- Programmable stream header processing via internal micro-controller including sequence, picture and slice header generation
- Basic unit and picture level rate control
- Multiple slices per frame (H.264 & MPEG-4)
- Programmable search range
- Dedicated hardware encoding
- Integer ME, sub-pel ME, intra search
- Transform/inverse transform
- Quantisation/inverse quantisation
- AC & DC prediction/inverse AC & DC prediction
- M-JPEG/JPEG features:
- All processing in core, host only needs to perform stream coding
- Two quantization tables
- Unlimited picture size
- Automatic hardware power management

- Wide range of video standards supported
- Low power consumption
- High quality compression
- Low host CPU-processing requirement
- Silicon efficient area
