- Scalable Resolution : Supports multiple resolution levels from a single compressed stream
- Region-of-Interest Coding : Enables selective quality enhancement for critical image areas
- Low Latency : <50ms encoding latency suitable for interactive applications
Limitations:
- Computational Complexity : Higher processing requirements than simpler codecs (MPEG, H.264)
- Power Consumption : Typical 1.5W power dissipation may require thermal management
- Cost Considerations : Premium pricing compared to consumer-grade compression solutions
- Limited Ecosystem : Fewer software tools and development resources than mainstream codecs
## 2. Design Considerations
### Common Design Pitfalls and Solutions
Power Management Issues
- *Pitfall*: Inadequate decoupling leading to voltage droops during high computational loads
- *Solution*: Implement multi-stage decoupling with 100nF, 10μF, and 100μF capacitors placed within 2cm of power pins
Clock Distribution Problems
- *Pitfall*: Clock jitter exceeding 100ps causing synchronization errors
- *Solution*: Use low-jitter clock sources (<50ps) with proper termination and isolated clock trees
Thermal Management
- *Pitfall*: Overheating during sustained full-load operation
- *Solution*: Incorporate thermal vias, adequate copper pours, and consider active cooling for enclosed environments
### Compatibility Issues
Memory Interface
- Incompatible with DDR3/DDR4 memory; requires specific SDRAM types (256Mb-1Gb)
- Limited to 32-bit memory bus width; cannot utilize wider memory architectures
Host Interface
- Parallel host interface may require level shifting when connecting to modern 1.8V/1.2V processors
- Limited to 16-bit data bus; may create bottlenecks in high-throughput systems
Video Interface Compatibility
- Requires external components for HDMI/DVI compatibility
- Limited native support for modern serial interfaces (MIPI, LVDS)
### PCB Layout Recommendations
Power Distribution
- Use separate power planes for analog (3.3V) and digital (1.8V) supplies
- Implement star-point grounding with separate analog and digital ground planes
- Place bulk capacitors (100μF) near power entry points and distributed decoupling near IC
Signal Integrity
- Route critical clocks as differential pairs with controlled impedance (100Ω)
