High-efficiency Codec Groups Included in the UniPhier Architecture
UniPhier's Low-power Technology
Low-power architecture
Multi-processor architecture
- Parallel processing optimized for media processing
- Multi-processor (IPP/DPP/CPU) parallel processing
⇒ Media processing at low clock frequencies
Stream DMA
- Hardware support for bit-string processing unique to streaming
applications; direct transfer of audio/visual streams to the UniPhier processor
⇒ Reduced CPU processing load and SDRAM access
Low-power display control
- LCD backlight control
- Screen effects using built-in memory and reduced external memory access
Low-power circuit technology
Aggressive gated clock control and block-specific power supply separation control
Board potential control,etc.
UniPhier as the Ideal Real-time Processing Platform
Assuring audio/video performance during convergent processing
- The UniPhier processor's virtual multi-processor architecture guarantees the performance of individual tasks during convergent processing.
- The memory control block guarantees individual data transfers for multiple DMA masters.
Reducing the CPU's processing load by masking real-time processing
- Real-time processing is masked to the UniPhier processor, freeing real-time processing from the operating system.
⇒ This approach assures audio/video and communications performance while reducing the processing load on the CPU.
Example: Audio/video stream multiplexing and separation, audio/video protocol processing, audio/video synchronization, etc.
UniPhier Secure Architecture
The UniPhier's secure hardware architecture and software control provide processing that is flexible, robust, and secure.
⇒ UniPhier delivers the safety and peace of mind for which digital appliances are known.
